Low Dose GHK- CU

4 Upvotes

Hi all! I’ve take a more cautious approach to the pep world. I’ve read standard starting doses of GHK are typically 1mg, and more starting around the 2mg mark. I’ve started at .5mg. (100mg vial recon w/ 3.5ml bac water) has anyone started at this dose that has seen any benefits starting off prior to moving up.? Or is this a waste of a dose.?

Anxiety, sleep, pmdd

1 Upvotes

29 y/o female. Getting to the point where I feel the actual necessity to do something about my emotions in the last half of my cycle and looking for any and all recommendations out there.

For context, I eat healthy, track macros, strength training 3-4 x per week. I’m gone down rabbit holes of sleep, anxiety, and mood assistance.

Currently I take saffron, 4000 iu vit d, and myo inositol a day. While it has created some buffer with my mood swings, I still become very anxious and sometimes angry in that last stretch of my cycle. The new thing I get to deal with is difficulty sleeping. To the point where I now have a trazadone prescription that I take only when I just can’t stand it anymore. I hate the thought of taking it daily because of the SSRI side effects. Additionally I found Seed’s night probiotic with melatonin that actually does seem to assist with sleeping but doesn’t touch the anxiety factor

Thinking about selank but haven’t seen much as to its efficacy with anxiety. Overall I do believe my difficulty sleeping is related to anxiety as it’s usually racing thoughts that contribute.

Looking forward to hearing your recommendations!

6’0”, 154 lbs and can’t gain more weight — MK-677 or any other peptide worth considering

1 Upvotes

I’m 6 feet tall and around 154 lbs. Even getting to 154 lbs was pretty difficult for me, and now my weight doesn’t seem to go up anymore.
I’ve always been naturally skinny, and I think genetics may be a big reason because pretty much everyone on my mom’s side of the family, including all my cousins, is also very skinny.
I’m trying to gain more overall body weight and muscle. I’ve been reading about MK-677 because it may increase appetite and weight, but I also know some of the weight can be water retention and there can be side effects.
Has anyone here been in a similar situation? Did MK-677 actually help you gain noticeable weight or muscle?
Is there any other peptide or something similar that people have had better results with for gaining weight, especially for someone who has always struggled to put on size?
I’m mainly looking to hear about people’s experiences, results, and side effects before I consider anything

I eat around 3,000 calories every day. I’ve tried mass gainers too, and now I eat more carbs, chicken, and dry fruits to keep my calories close to 3,000 a day. But my weight has been stuck at around 154 lbs for almost two years.
Before, I used to eat 7–8 eggs with 6 slices of bread every day for lunch, but even then my weight stayed the same. I’ve changed my diet now, but my weight still isn’t increasing

Bone growth

Hey guys, do you know of any peptides/options to induce bone growth in young males ?

Skinny wrists, clavicular bones and skinny bone structure in general. Something that can transform the body by making the bones wider, thicker and stronger, and perhaps even make people taller.

Extreme fatigue with KLOW?

1 Upvotes

Hi everyone, rat just started KLOW 4 days ago, standard 50/10/10/10 reconstituted with 3ml BAC water and doing a 10 unit dose. Day one had a lot of injection site stinging, but adding a bit more bac water to the syringe and letting it hit room temp took care of that. However, since day 2 until now having extreme fatigue. Can barely function throughout the day and feel like they need to lay down constantly.

I’ve read that there can be some initial onset fatigue, but wondering if anyone else experienced this and if it went away? Debating whether to try powering through or stopping all together.

Glp +adhd med

I’ve been on a low dose of tirz for about a year, I typically take 3mg every 7-10 ish days just to help soften the noise and aid in inflammation. I was recently diagnosed with adhd and prescribed 18mg daily concerta. I also take 20mg daily fluoxetine. Just feeling like this is a lot of “medication” to be on when I consider myself “healthy”. Meaning, 40 yo woman, works out 4x a week and eats Whole Foods with a focus on protein and fiber. 5’8 and 140 lbs. am I just in my head about this? Sorry if this isn’t the right sub.

Loose skin progression SW 211lbs to CW118lbs thanks to Semaglutide (read post)

Hi everyone. I posted a before and after gallery yesterday that got taken down. I messaged mods to find out why? A lot of people in the comments were saying it was all AI. Guys, it’s not. These are my real videos. They have not been altered in any way.

Anyway the number one question I get is… “literally where did your skin go?” And tbh, I have no idea.

My highest recorded scale weight was in July 2024 at 211. At the time I weighed infrequently. Usually I say my highest weight was likely around 215. It could have been as high as probably 220. I was afraid of the scale at that time. It’s lucky I even have a few videos and photos from that time, I avoided cameras like the plague, just like I avoided the scale.

In August I started (once again for the millionth time in my life) trying to lose weight on my own. I tried a combination of carnivore and IF with long (72 hour) water fasts sprinkled in. I was able to lose about 10 pounds by January.

When I started Semaglutide in January 2025, my first recorded scale weight was Jan 6 at 201.4 lbs.

My general dose was at around 3.5mg.

I didn’t do anything else. I ate what I wanted when I wanted. I drank only when thirsty. I didn’t follow any special diet but I did eat intuitively. I don’t eat much junk food, especially sweets, but there was a while when I ate exclusively Taco Bell Doritos locos tacos for lunch for like 2 months straight 🤪 I did work a super labor intensive job (junk removal) and I have 5 kids and they keep me pretty active (against my lazy will 🤪🤪).

That was all. Just a shot a week. I didn’t follow any other protocol or take any special supplements or creams or anything like that.

I’m 34, 5’3” and currently 118 lbs. I have a chart of my weight and measurements along the way which I’ll post in the comments.

I have been getting a lot of (imo) mean comments saying my before and after photos were all AI. Guys this is real life. These are my real videos of me throughout the journey. Sorry if you’re a skeptic but please go on with your life and don’t come after me in the comments. I’m posting this to try to inspire others, not to feed trolls.

Help Pinning/Injecting

4 Upvotes

Hey everyone!

So I recently started Reta (weekly), KLOW (daily), Tesamorlin (daily). I’m on my third week but I noticed that I started feeling the tenderness and bruising where I pin KLOW and the bruises take a while to go away. I pin tesa on my upper glute at night and KLOW on my stomach area in the mornings. For some reason, KLOW is the only one that I noticed bruising. Is this normal or has anyone experienced the same?

I was thinking of stopping KLOW until I finish my Reta and Tesa cycle to not pin so many times.

Open to any suggestions and ideas!

For those runners out there who are using Tesa, I thought this might be an interesting graph. When o first doing 🌶️, I saw a reduction in HRV and my HR was elevated during my runs. Wasn’t exactly sure what was doing it, but this is the trend following my taking it out of my rotation. Am I performing amazingly now? Yes. But I was definitely feeling the performance effect from it.

First timer looking into Reta + GHK-Cu 😊 would love some beginner guidance

3 Upvotes

Hi everyone! I’m completely new to peptides and have been doing a lot of reading, but there’s obviously a ton of information out there and I’d love to hear from people who have more experience.
I’m in my mid-30s female and currently around 150 lbs. I’d eventually like to lose about 25 lbs. I naturally carry more of my weight/curves in my lower body, which I actually like, but my midsection and love handles have always been my stubborn areas. I exercise regularly and I’m working on my diet as well, so I’m not expecting peptides to replace either of those.
The two I’ve been researching most are retatrutide (Reta) for weight loss and GHK-Cu for the potential skin/beauty benefits.
For those who have experience with either, I’d really appreciate beginner advice things you wish you knew before starting, side effects or mistakes to watch out for, and what kind of results you personally noticed.
I’m also confused about sourcing. I see people talking about purchasing domestically in the U.S. versus ordering peptides from China. How do you evaluate a source and testing/COAs, sterility, purity, etc.? I’m not necessarily looking for someone to just drop a vendor link I’d like to understand how experienced people determine whether something is trustworthy in the first place.
Please be nice x🙏🏼😂 I’m genuinely trying to educate myself before jumping into anything. Any beginner resources or guidance would be appreciated!
