I will hazard a guess and say that most people who stack do it because of effects/Side effects. Some Find that reta works well in burning fat, but are worried about lack of apetite suppression so they shift Sema is added.Qui
Are you saying that there is absolutely 100% no possible way that a fine tuned “stack”of peptides could have a positive effect?
Some find that the Tirz they need to lose weight is on the lower end, but since Tirz has a rather weaker GLP-1 effect, they opt to add a tiny amount of Sema (which is too strong for them normally).
People in pharma will tell you these stacks are wasteful. Myself finds a Reta + Tirz stack a fancy way of wasting money. IMO Only Sema is worth stacking with anything else, essentially because of the appetite effect. This is a very personal opinion. The jury is out on stacking. Anecdotally it works for many. Then again monotherapy also works for many. Peeps will be peeps. There are no studies out there for this and there isn't any reason for companies to study stacking for now. Everyone is busy finetuning their repertoire of weight loss meds, why would they test whether a rival's meds works well with theirs?
For sake of harm reduction (financial harm inclusive) Stacking Glps not really worth the hassle. The more cavalier can try stacking sema with other things or stack a GLP with an amylin analogue. In the future GLP-1s will most likely be stacked with some lean mass increasing med (For the sake of middle aged and elderly fatties who will most likely be unable to 'gym' hard enough to retain lean mass). For now though, Stacking 2 glp-1s is 'short-cutty' and is not sustainable long term (financially and discipline wise). I would assume once people reach goal weight they mostly just stick to one med
