Combining Reta, Tesa and Mots-C

Summary

Can reta, tesa and mots-c be drawn into one syringe and injected together?

Most participants advise against mixing the three peptides in a single syringe. Concerns include unknown interactions in solution, risk of clumping or degradation, immune reactions from mots-c inflammation, and loss of ability to identify which peptide caused a side effect. Short-term drawing and immediate injection is viewed as lower risk by a few, but still considered unnecessary hassle compared with separate shots. Tessamorelin and reta are singled out as especially fragile.

Hey there, would it be possible to draw up those three items together into a single needle for one shot? Something like pulling twenty units of reta plus ten units apiece of tesa and mots-c all into the same barrel?

I've noticed that handling those three shots correctly tends to be less risky and more straightforward overall.

Based on stuff I've come across, these GLP-1 compounds aren't supposed to go together in one shot. Some other peptides mix okay, with certain combinations getting a lot of attention, though the GLP-1 types seem fine by themselves.

It's feasible to combine them but I doubt that's smart given that their behavior when blended isn't understood. The terrible swelling effects from one might cause my body to start fighting the remaining pair too.

Is mixing them off limits since it would wreck the peps or since it would wreck me instead?πŸ™ƒ

Mixing them ruins the peptide and makes it look curdled. Those GLP compounds work fine among themselves but nothing beyond that. B12 with the amino blend and NAD combine okay even though they stay acidic. The rest of the peptides usually handle being grouped together. Clumps forming inside the syringe show the mix won't stay stable.

Most folks go with separate shots each day instead. Skipping that might mean this route just isn't suitable. Picking a riskier path only to dodge a few small needles strikes me as pointless. Pinpointing exactly which item triggered trouble and at what spot helps sort things out if issues appear. Pulling from several containers at once raises the chance of mistakes. One breaks down fast so blending gets avoided. The other brings safety worries when combined too. Forcing the needle past extra seals tends to increase the sting. Blending might trigger sensitivity across more than one if any single one causes problems. Grown adults can pick whatever option seems best even with those risks.

This concept appears in different forums here and there. I wouldn't consider it definitive but it seems like a handy note. For my everyday shots I prepare multiple pens ahead of time and finish them off. Setting them up takes some effort initially yet since mixing and cleaning is part of my routine anyway there's hardly any added step to load a pen cartridge over using a bottle. Plus this reduces the time spent on each shot and makes carrying things simpler during trips and so on.

I believe there's been a mix-up in what I meant. That snarky attitude isn't necessary, especially since you mentioned we're grown-ups who can communicate properly. Just to clarify, needles don't scare me; I simply wondered about a simpler approach than what I'm familiar with. Actually, I find the injection process amusing and kind of like it. So avoid jumping to conclusions about someone you don't really know online. But thanks anyway for the input!

Appreciate this so much, it's been a huge help!!

Honestly combining those compounds into a single needle feels like extra effort compared to giving each one separately right in a row. These days I'm handling three separate ones and sticking with that approach. I never even thought about combining them for a single injection. Still individuals vary with their own preferences and requirements.

GreenMeadow54archiveJun 14

I wouldn't mix extra peptides into the same container alongside GLPs. That approach strikes me as unwise. Loading needles ahead of time feels equally problematic. Pulling several peptides including a GLP into a single needle for immediate use could work out okay. Breakdown isn't going to occur over such a brief interval. Yet handling the whole procedure correctly ends up feeling really tedious.

I see where you're coming from. My idea was to use a blend that already combines three separate peptides inside a single container, so combining them during one injection seemed like it would hardly matter.

Stability varies based on the specific compound and how much is present. Research from around the start of the century indicates this works well and holds up for certain meds like antibiotics and similar compounds in emergency hospital settings, including some pediatric ones. Even morphine stays good for a couple of years. Those GLP-1 things haven't been checked yet. Preparing one ahead and storing it cold overnight shouldn't cause issues though. Watching that guy in the clips makes me uneasy since his methods aren't ideal. The bubbles and shaking he does might break things down or create clumps. I guess I'm picky about these details, similar to how medical scenes on screen bug me with their sloppy technique.

CopperSignal27archiveJun 15

Usually I draw three separate compounds together into one shot without precombining them inside their original containers since that tends to create problems. So far this method has caused me no trouble. Doing it ahead of time can make them clump and lose strength. Still the specific ones being discussed tend to break down easily. A brief period inside the syringe is probably harmless yet the time spent absorbing under the skin might create issues. Most users also notice skin reactions from one of them so I skip mixing that one and choose my outer leg instead of the belly area since it produces smaller lumps and less itching.
