Can you draw multiple peptides into the same needle?

I placed an order for KPV, Selank, DSIP and Glutathione. I'm already on tirz.

This is the schedule I've come up with. Having to do 5 pokes a day seems a bit excessive. I was thinking I'd take the KPV, Selank and DSIP in a single syringe and the Glutathione and tirzepatide in their own (glut because volume will be too big, tirz because I saw you should never mix it with anything). Thoughts? Also, do these starting doses look good? I'm having a lot of trouble figuring out dosing for them.

GLPs don’t play nice with anything and shouldn’t be mixed in the same syringe. It’ll make a really thick gel that, even if you could squeeze through your 29-31 gauge needle, you wouldn’t want to. This is the chart everyone posts with regards to mixing of peps in a single container. I don’t have any experience with it, but I feel like gluta needs to be on its own too. I’m sure someone will correct me if I’m wrong.

Best bet is to figure out what time of day is the most effective for each (morning/night/before workout/fasted/etc) and then see if there are any synergies.

You beat me to it. Make sure to read the disclaimer at the very top. I'm not sure how accurate data from wellness clinics are, but it's probably better than nothing.
 
I mix reta/sema or tirz/sema in the same pin without issue... but glutathione I do separate cuz it burns and smells like Sulphur, phosphorus and the depths of hell. It gets a dedicated pin. Well I use a 3cc 23 Guage for the glut cuz mine was so thick. I add 3cc of bac to a 1200mg vial and do 1.5cc twice a week. Is there a way to do it in a slin pin? Thought warming it up ruins it quickly?

Thanks! I did see I couldn't do GLPs and this confirms it. Looks like the first three (KVP, Selank, DSIP) can be mixed together so that makes it much easier. I can just draw all three into the same syringe and then do the gluta & tirz separate. Appreciate the response.

is a 23g painful? And when you reconstituted it, it was actually thick? could you add more BAC to thin it out?

It doesnt really hurt, no more than a 25 or 27g...You could dilute with more bac but who wants to pin a full 2cc three times a week.... if it's heated just a little it would push through any guage needle but everything I'm reading says even 45 minutes at room temp after reconstituted will render it useless....lol I'm researching liquid liposomal glutathione as we speak. But maybe I'll try 4.5 cc of bac and do 3 1.5 injections.

Glp1 with another glp1 is a gray box not red.... been doing this over a year and no gel like substance.
 
Yes, sir. Fair enough. I made an over-generalization. I had the last doses of reta & SS-31 and thought, “eh, why not?” It was like epoxy!
There's no research on it unfortunately. Just the assumption and I believe it that it would increase sides with the worst being pancreatitis.....waiting for someone to say ill/well be fine cuz a lot of us do it.... you may be absolutely right and instead of extending our lives we're shortening it. A found a couple "spa" places saying they have the same ph values and it's OK at conservative doses but everything else says "You'll shoot your eye out Ralphie."

You can pull it up in a large gage luer lock while keeping the vial cold, then switch the needle to a thin gauge while letting the syringe warm up. That might allow you to pin a 30g without the risk of degrading the whole vial.
