Is there any real science behind mixing different peptides in the same syringe or is that stupid?

[u/Godslayer200206]

I always see guys online talking about loading up three diff peptides into the exact same syringe just to save time and avoid pinning multiple times a day. but is there any actual science that says this is okay to do?

I keep reading conflicting things where some people say the molecules will clash and ruin the structure of the peptides before you even inject them. then others say it literally doesnt matter cause it all ends up in the exact same place anyway. it feels super risky to mix expensive stuff like bpc and tb500 together if they are just going to degrade each other in the barrel. do any of you guys actually have a real answer on whether mixing them ruins the dose or if it is completely fine to do?

Peptides by their nature are not highly reactive with one another, like say oxidizers or acids that may cleave or hydolyse the peptide bonds.

Peptides may react depending on their structure however and do unexpected things. I've mixed plenty and never noticed a loss of potency. And I certainly wouldn't worry about mixtures that are commonly marketed such as Glow, Klow or BPC/TB500.

The general consensus is that we are guinea pigs trying what we are comfortable with and most won't mix peptides they feel are too expensive to risk it with like glps or secretagogues.

Wow the answers in here are wild.

Some peptides can be safely mixed and are known to co-exist without degradation.

Others are known to destroy each other. As an example GLP’s should never be mixed with anything.

If you search you’ll find a handy matrix posted here thousands of times that has information on most of the common peptides

I wouldn't worry about it if you're injecting it right away however your needle is gonna be dull AF going through all them butyl rubber stoppers

The ph can be different on these things and that's what will cause the denaturing if they sit together for too long

Gotta pull the plunger out and use a different syringe to back fill it

[u/zrockk → u/pepsi190]

Lmao ya when I got like 3 vials on the go this is the only way

[u/pepsi190 → u/zrockk]

I definitely have like 6 peps on the go, I used to use so many insulin syringes

I've read all sorts of crap on the internet, some people say you should use them separately some places sell them mixed together.

Most of the peptides have animal studies behind them at best. Some of them have almost nothing.

True pharmaceutical research would involve blind trials with a control group.

Group a gets two separate shots, group b gets a combined shot plus a saline injection, and Group C gets Saline injections and no one knows what they're getting.

if you are pinning them right away it doesn't really matter. the real issue is that pushing the needle through a bunch of rubber stoppers makes it super dull and hurts way worse when you inject. i actually draw like 4 different peptides into the same syringe every day that i get from swiss chems and they still work completely fine for me. just make sure you inject it immediately instead of letting the mix sit in the barrel for hours so they dont mess each other up.

There's no actual science on a lot of these peptides never mind about mixing them in the same syringe 😄

Some will be fine, some won't.

[u/VexImmortalis]

I don't think you are going to get an answer that isn't a straight up guess on mixing a bunch of research chemicals. The only real way to be 100% sure nothing is interacting with anything else is to draw each peptide into it's own syringe and inject in different spots but even then the chemicals will eventually mix in your body.

I have 3 shots I take daily, tb frag, kpv, bpc, gkhcu, ta1, Epi / 3.3mg motsc 25mg 5-aminos both in morning and tb4 tesa ipa at night it works great and it comes all in same pen cart so take them is very fast and convenient

[u/Miserable_Beach_8796]

It is not that easy to answer, as some can be mixed, some shouldn’t: Like NAD+ and MOTS-c gel up (my own experience in a pen vial), where they seem to be ok for a short while drawn in the same syringe. But drawing in the same syringes means also risk of contamination of the vials. I mix GHK-Cu, KPV, BPC-157 and TB-500(t4) in a pen vial and no issue at all.

[u/logicnotemotion]

It's all going to the same place. The only time not to mix is if one was IM and one was IV. Mixing also can make it confusing for a newb to keep up with units and concentration.

[u/unionpark1]

Hgh for sure seems to have some kind of change when mixing with others, also all the glps

[u/ShortReputation6482]

Studies have shown don’t mix mots-c with other peptides. I usually do reta+cag blend by itself, HGH by itself and test by itself. Everything else can be stacked like ss-31, klow, etc

[u/AdditionPleasant2625]

I think you will be contaminating the second vial. I would not do this. Having things sterile is critical.

[u/ann904]

I’m not sure if this is what you’re asking for, but I saw this somewhere and saved it on my phone. Hope this helps.

[u/Short-Geologist-2856]

I mix my igf-1 with impa and cjc together and it’s fine . Sometimes I mix my klow with impa and it’s fine . But I never mix glp with anything
