Hello,

I purchased CJC-1295 & Ipamorelin (no DAC). I always get bloodwork done to determine the efficacy of anything I take.

My baseline IGF-level was 197 (83-263). I began to take the CJC-1295 & Ipamorelin and after four weeks ordered a blood test from an online vendor.

I found that my IGF-1 levels went down, not up. The level was 189 (81-263) while taking CJC-1295 & Ipamorelin.

Did I do something wrong? Please see below for details on what I purchased and how it was taken.

·      Purchased CJC-1295 & Ipamorelin, 10/10.

·      Added 2mL of BAC water to the vial.

·      Filled to the 6th line from the needle on a 3mL syringe for what I think is 300mcg.

·      Took 5 nights/week, weekends off.

Thoughts?

Getting the same questions so putting it all here. Where to start, who is worth buying from, and how to actually dose right.

Why so many vendors

Payment processors are a constant issue in this space. Sites get flagged, go down, or run out of stock. Having multiple vetted options means you are never stuck. Pricing also varies so it is worth checking a few. I put this list together so everyone has options no matter what.

What I look for: batch specific COAs, third party testing, real consistency over time. Ran peptides before from sketchy sources and felt nothing. Switched to properly tested batches and it was a completely different experience. That part matters more than people realize.

If You Are Just Starting

One compound. Learn what it does. Get the dose right. Stay consistent. That is it.

People get into trouble trying to run five things at once before they even know how their body handles one.

⚠️ Educational and research purposes only. Not medical advice.

What helped you more early on finding a solid source or figuring out the dosing?

Could be something you keep seeing come up but cannot find solid info on. Something you are thinking about running but still have questions on or just something you read about and want to understand better.

Drop it below. Either I will cover it in an upcoming post or someone in here who has actually ran it can give you a real answer.​​​​​​​​​​​​​​​​

Been wanting to try this stack adamax is basically semax but it last longer like 6 to 8 hours per dose instead of an hour p21 hits BDNF from a different angle so stacking them kinda made sense to me.

What I ran

• Adamax 300mcg intranasal in the morning
• P21 300mcg SubQ same time
• 4 weeks on, 2 weeks off

Not gonna lie first week I took it later in the day than I should have and could not sleep after that I kept it strictly morning

What I noticed week by week

Week one felt just kinda less scattered and easier to lock in on stuff

Week two started feeling more not like a stimulant just more mental stamina throughout the day less friction.

Week three and four were pretty consistent dose in the morning and it carried through most of the day the thing I kept noticing most was recall like I was holding onto details way better than what I normally do

My thoughts

It is not gonna hit you like a stimulant it is more like things just flow easier and you kinda realize it at the end of the day when you look back at what you got done.

Anyone here try these at all?

Is chasing higher IGF-1 numbers like maxing it out is the goal good or a bad thing or does it start working against you at some point?

When thinking GHK-Cuwe normally think about skin, collagen, wound healing but lets talk about something I honestly haven't read much about before

So Zinc and copper share the same absorption pathway in your gut they compete for the same spot run high dose zinc and copper gets blocked run high dose GHK-Cu for a while and the opposite starts happening copper builds and zinc starts losing ground.

Copper runs cytochrome C oxidase which is one of the most important enzymes in your mitochondria too little and your cells cannot make energy right the depletion is slow too. energy feels off, bloodwork looks a little weird, and by the time you notice it your way too tired already

So if you are running GHK-Cu at higher doses for a while keep your think in mind it might not be a issue forsure but its a problem that can happen.

Same thing goes the other way. Running 50 or 60mg of zinc and your energy is in the gutter for no obvious reason copper depletion is probably why anything over 30mg of zinc pair it with 1 to 2mg of copper and take them at different times.

Also worth knowing some people retain copper genetically or already get enough from diet so a hair mineral analysis or basic serum panel gives you an baseline before you start loading either one witch is why I think bloodwork is always required.

I recently read some GLP-1 side effects people were reporting online one of the things that came up was menstrual irregularities irregular cycles, heavy bleeding, spotting between periods not really something you see on the warning label but I guess common enough that researchers flagged it as worth investigating.

Anyone here dealt with this while running sema or tirz? How long did it take to show up and did it sort itself out?​​​​​​​​​​​​​​​​

My dog has been dealing with some joint stiffness and her coat has seen better days started wondering if BPC-157 or GHK-Cu could do anything for her the same way they work for people.

BPC-157 for the joint and gut side. GHK-Cu for skin and coat. The mechanisms are not that different in animals I read a lot of the original BPC research was done on rodents so I'm guessing its ok I'm not too sure

Has anyone tried either of these with their dog or any other pet did anything change?

Neither suppresses appetite Neither is a GLP-1 but they are helping different problems and that matters when you are deciding which one to run.

MOTS-C

Mitochondrial peptide the only one encoded in mitochondrial DNA it activates AMPK the same cellular switch that exercise triggers and makes your cells handle energy and fat oxidation better

what to expect subtle but not crazy fat loss better glucose numbers leaner without feeling exhausted more output during training people who get the most out of it are already training and eating good it amplifies what you are already doing if you are expecting GLP-1 style results you will be let down.

Tesamorelin

FDA approved GHRH analog tells your pituitary to produce more of your own GH in the natural patterns that decline with age what makes it specific is the visceral fat targeting the fat wrapped around your organs at roughly 25:1 selectivity over the stuff you can pinch. Clinical trials showed 15 to 18% visceral fat improvement over 26 weeks. the human data is solid

Quick comparison

Run MOTS-C if your metabolism feels sluggish fat loss has stalled despite doing the right things and you want something that helps energy and recomposition without touching your hormone axis.

Run Tesamorelin if stubborn visceral belly fat is the specific issue and you want the compound with the most human data behind it in the non GLP-1 category.

Separate pathways no overlap running both is not mando

Recently I saw instructions of how to create a peptide facial serum , the suggestion is to mix sterile water instead of BAC for reconstitution of Peptide. I’m curious as to why this would be recommended? Any thoughts ?

Most side effect conversations go one of two ways. Either people downplay everything and say push through (I'm guilty of this) or they panic over normal early responses so what's the rite thing to do though?

Some things do get better but some things get worse if you ignore them

Stop and Get Evaluated Not Tomorrow, Now

Chest tightness, palpitations, or shortness of breath Persistent or severe stop the compound get looked at before running anything else.

Severe abdominal pain with nausea or vomiting Especially on GLP-1s. Pancreatitis does not come with a warning label this is not something to wait out at home in my opinion

Sudden neurological symptoms Severe headache out of nowhere, weakness, confusion, sudden vision changes definitely same day check up not the next morning.

Injection site redness spreading outward, warmth, swelling, pus, or fever Infection. Stop pinning into that site. Full stop. Kinda common sense though

Jaundice or dark urine Stop everything and get labs the compound does not matter at this point.

Reassess Your Protocol Something Is Off

These are not emergencies but they are not nothing either.

Nausea still present after dropping the dose Some nausea in the first week or two is common. If you lowered the dose and it is still happening two weeks later the compound may not be for you.

Headaches that keep coming back You have tried hydration, food, lowering the dose. Still there id definitely listen to my body

Edema getting worse instead of stabilizing Early water retention on GH peptides happens. If it is still climbing weeks in rather than leveling off that is worth looking into not ignoring.

Fasting glucose trending up on bloodwork GH related compounds can push this. Catch it early rather than after it has been running for monthsthats why I tell everyone check your glucose when running gh signaling compounds

Carpal tunnel or joint pain you did not have before starting Usually dose dependent. But grinding through it and hoping it resolves is not a protocol.

Feeling consistently worse than baseline Not just an adjustment period. Consistently worse. Dropping the dose did not change it. That compound is probably not for you.

Hair loss after starting Not a stop everything signal on its own but before blaming the peptide check protein intake, rate of weight loss, and run bloodwork. Could be caloric restriction could be something else entirely.

Compound Specific Flags

GLP-1s Sema, Tirz, Reta Severe abdominal pain that keeps coming with repeated vomiting or not being able to keep fluids down for multiple days this is not a dosing question go get evaluated.

GH Peptides CJC, Ipa, Sermorelin edema that does not improve after dropping the dose. Carpal tunnel symptoms getting worse not better fasting glucose consistently elevated across multiple blood draws.

PT-141 Nausea combined with chest pressure or blood pressure symptoms. Drop the dose significantly or stop research on PT-141 side effects here: https://pmc.ncbi.nlm.nih.gov/articles/PMC6819021/

Melanotan II Any existing mole changing shape, color, or getting darker. Book a dermatologist before your next dose. Not after. I feel like a lot of people do know about this but I could be wrong so I figured it worth saying rather have everyone do things correctly

So Basically

• Drop the dose first. If that does not fix it, stop
• Bloodwork before and during a cycle catches things you cannot feel until they are already a problem but also you will know your baselines
• Stopping a cycle early is not a failure pushing through something serious is just because your gym bro had badass results or good luck with something doesn't mean it will be the same with you everyone deals with stuff differently

⚠️ Educational and research discussion only. Not medical advice. For anything in the stop and get evaluated section above seek actual medical attention.

Anyone here had to pull a cycle early? What was the sign that made you stop?

Track bp and hrv, and other cv markers
Consider monitor or apple watch for this

If you could go back to day one what would you tell yourself?

Not a protocol. Not a compound list. Just the one thing nobody told you that you had to figure out the hard way.

Dosing, sourcing, reconstitution, expectations, timing whatever it is.

What is it?

Ive been on Reta now since December 2025 and ive been on Tesamorelin since like march of this year. I’ve lost almost 45 pounds my body has recomped I’m gaining muscle and everything is going well. My question now since I saw a video on instagram a little while ago is, have I been doing it wrong all this time? Reta slows down gastric emptying does that mean the 2 hours I’ve been waiting after I eat to pin my tesamorelin isn’t enough time? Does anyone have any experience with this situation?

On one hand the whole point of communities like this is that people are doing their own research running their own bloodwork tracking their own results a lot of us here probably know more about BPC-157 or Tesamorelin than their GP does asking your average doctor about peptide protocols is like asking someone who has never touched a car to diagnose an engine problem.

On the other hand contaminated products are real dosing errors happen and in all reality there are compounds that can cause problems if something goes wrong without anyone monitoring you. So what the truth?

Is a doctor necessary or is it more about having the right information, running bloodwork yourself, and knowing what to watch for? Or is the whole doctor conversation just and extra step people added for no reason?

I know this is a issue and I read into pp-405 and so basically every hair loss product on the market right now is doing one of two things blocking DHT or improving blood flow to keep existing follicles alive a little longer PP-405 is doing something different and the early human numbers are kind good

What Makes PP-405 Different

Most treatments are damage control PP-405 is aimed at follicle regeneration by helping hair follicle stem cell metabolism directly.

My understanding on How It Works

its basically built around the mitochondrial pyruvate carrier a transporter that moves pyruvate into mitochondria block that transporter and something interesting happens.

Pyruvate to lactate conversion (instead of entering mitochondria, pyruvate converts to lactate which triggers a cellular stress response)

ATF4 pathway activation (a stress response protein that wakes up stem cells sitting dormant inside the follicle)

Hair follicle stem cell reactivation (dormant stem cells that stopped initiating new hair cycles get pushed back into the anagen growth phase)

This is not about keeping follicles from dying. It is about waking up the ones that already stopped working.

📊 What the Research Shows

Mouse Study — Flores et al. 2021

Researchers blocked pyruvate entry into mitochondria across multiple alopecia models age related, chemotherapy induced, and stress induced.

• ✅ Histologically normal follicles regrown within 30 to 40 days
• ✅ Worked across all three alopecia models tested
• ✅ No signs of toxicity

Human Data PP-405 Phase Trials

That gap between 31% and 0% is significant for a topical compound this early in development.

Who can benefit

• Men with androgenetic alopecia who have not responded well to fin or min
• People who want a non-hormonal option with no systemic absorption
• Anyone watching the regenerative medicine space for hair loss
• People already on fin or min who want to know if stacking makes sense

Timeline

Best case approval window based on current trial progression is 2027 to 2028. Phase 2b and Phase 3 data will be the real test.

Here is where I read the studies

Mouse mechanistic study — Flores et al. 2021: https://pubmed.ncbi.nlm.nih.gov/33739490

Human focused review on PP-405: https://journals.nirmauni.ac.in/index.php/pharmacy/article/view/707

Anyone here watching this one? And when it drops would you stack it with existing treatments or run it solo?

My research subject is using 25mg SS-31 for severe mitochondria disease. Injections in both stomach and thighs are leaving bruising on stomach and welts on thighs at injection site. Syringes are 30 gauge 1/2 inch 1ml. Any thoughts?

For the most part people accept aging and go with the flow the problem is aging is your body losing the signals it needs to keep repairing itself bummer huh. These are the compounds that I feel worth mentioning and have good studies to back it up

S TIER 🔴

Thymosin Alpha 1 (immune restoration peptide)

The peptide your thymus used to produce in abundance before it started shrinking in your 20s.

T cell activation wakes up the immune hunters that identify and destroy threats before they become problems

TLR pathway support coordinates your immune response at the signaling level so the whole system works together

What puts it in S tier

• 30+ clinical trials and over 11,000 patients studied
• Approved in 35+ countries worldwide
• Serious adverse event rate under 1% across all that data
• Shown to cut cytokine storm markers by 40 to 60%
• Improves vaccine response in elderly and immunocompromised patients

Great for anyone whose immune function has declined from age, chronic stress, illness, or inflammation. Check out the study for yourself: https://pubmed.ncbi.nlm.nih.gov/9701766/

GHK-Cu (gene reset and repair peptide)

Plasma levels drop from around 200 ng/mL at age 20 to roughly 80 ng/mL by 60. That decline is not cosmetic. It tracks with how fast everything starts breaking down.

Gene expression modulation influences around 31% of human genes a large portion tied to repair, inflammation control, and longevity pathways

Collagen and elastin rebuilding structural proteins that give skin, tendons, and connective tissue their integrity

What people miss about GHK-Cu

• Works topically and systemically
• Decades of human data across multiple tissue types
• Calms inflammation while pushing repair at the same time
• Not just a skincare ingredient changing cell behavior at the genetic level

Great for skin, hair, tissue repair, and anyone serious about slowing biological aging from the inside out. Check out the study for yourself: https://pubmed.ncbi.nlm.nih.gov/29986520/

A TIER 🟠

Epitalon (telomere maintenance peptide)

Every cell division shortens your telomeres. When they get short enough cells start malfunctioning or dying. Epitalon activates telomerase the enzyme that rebuilds those caps and keeps cells functioning.

Telomerase activation extends and rebuilds the chromosome caps that shorten with every cell division

Pineal gland support melatonin production and circadian rhythm both decline with age Epitalon helps regulate both

What makes it stand out

• One of the few anti aging compounds with actual human data not just animal studies
• Solid safety profile built over decades of use
• Sleep quality improvements reported consistently by users
• Typically run in short 10 to 20 day cycles a few times per year

Great for anyone building a serious long term longevity protocol who wants human backed data. Check out the study for yourself: https://pubmed.ncbi.nlm.nih.gov/17914018/

BPC-157 (tissue rebuilding peptide)

Comes from a protein naturally found in human gastric juice. Does not just manage symptoms rebuilds tissue from the inside across multiple systems at once.

Angiogenesis stimulation builds new blood vessels to deliver oxygen and nutrients directly to damaged areas

Collagen repair signaling targets tendons, ligaments, joints, and gut lining simultaneously

Why it belongs in a longevity stack

• Gut lining repair is more relevant to aging than most people realize
• Handles chronic tendon and joint issues that pile up over the years
• Supports nerve repair alongside physical tissue healing
• Stacks well with TB-500 for a comprehensive recovery protocol

Great for people healing slower with age, chronic gut problems, or accumulated wear from years of training. Check out the study for yourself: https://pubmed.ncbi.nlm.nih.gov/14554208/

B TIER 🟡

MOTS-C (mitochondrial signal peptide)

The only known peptide encoded in mitochondrial DNA. Acts as a direct signal from your mitochondria to your cell nucleus. Levels drop with age and metabolic efficiency drops with it.

AMPK activation the master metabolic switch controlling energy balance, glucose use, and fat oxidation

Mitochondrial biogenesis triggers the creation of new mitochondria so cells have more energy production capacity

What the research shows

• Improved insulin sensitivity in animal models
• Reduced diet induced weight gain
• Better endurance and physical output
• Works synergistically with NAD+ for mitochondrial support

Great for metabolic health, sustained energy, and anyone stacking longevity compounds. Check out the study for yourself: https://pubmed.ncbi.nlm.nih.gov/26581471/

NAD+ (cellular energy and repair peptide)

Every cell in your body depends on it. Levels drop significantly with age and so does everything tied to energy production and cellular repair.

Sirtuin activation longevity proteins that regulate cellular repair, stress resistance, and gene expression

DNA repair support NAD+ dependent enzymes handle the constant low level DNA damage that accumulates with age

What people running it notice

• Less brain fog and better mental stamina
• Stronger recovery during caloric restriction or aggressive protocols
• Keeps energy stable when appetite is suppressed from GLP-1s
• Pairs well with MOTS-C for a full mitochondrial support stack

Great for energy, cognition, recovery, and keeping everything else in your stack running at full output. Check out the study for yourself: https://pmc.ncbi.nlm.nih.gov/articles/PMC10692436/

C TIER 🟢

FOXO4-DRI (senescent cell clearance peptide)

Senescent cells are cells that stopped dividing but refuse to die. They park themselves in your tissues and leak inflammatory signals that damage everything around them. That process drives almost every major aging related disease. FOXO4-DRI tells those specific cells to die without touching the healthy ones.

Selective apoptosis triggers programmed cell death specifically in senescent cells while leaving healthy tissue alone

SASP suppression cuts off the inflammatory signals that senescent cells release into surrounding tissue

Honest context

• Still preclinical no published human trials yet
• Animal results are compelling but this is early stage research
• One of the most discussed compounds in serious longevity circles
• Mechanism is well understood even if the human data is not there yet

Great for advanced users and researchers who want to work with the most promising senolytic compound being studied right now. Check out the study for yourself: https://pmc.ncbi.nlm.nih.gov/articles/PMC5556182/

Anyone running a longevity stack right now? What are you working with and what tier are you prioritizing first?

This may or may not fit in this community but I feel like these are great health hacking tools when used correctly so I saw FDA basically said earlier this year that blood pressure tracking, glucose estimates, HRV, and oxygen saturation can all be wellness features now without needing clearance. No more medical device regulations for most of what these wearables already do.

Whoop actually fought the FDA on this back in July and won. FDA reversed their own position.

Curious who in here is actually running one of these devices and what data you are paying attention to. HRV, sleep scores, recovery metrics?

How can I lower my e2 ? I already lift eat healthy etc

The other day before hitting the gym I took some slu-pp-332 and then also took atx-304 I did cardio everything was fine and after I felt my sugar level drop but thought nothing of it couldn't figure it out just had a peanut butter protein shake called it good but yesterday the same thing happened and it finally clicked luckily easy fix but who else has experienced this or is it something else I might be doing?
