There are many peptide testing spots. Pick one.
AFI, chromate, freedom, janoshiek.
If youre broke you can send one to Finnrick for free. Be advised thats the most dubious of the sort.
Dude get a grip, test if you want some peace of mind, but don't indirectly tell others that its "bunk" because bba has been pretty solid so far with reta.
Brother, what is it you're looking for? Do you want appetite suppression? If so tirz has a harsher effect of this than reta. You will need higher doses of reta to achieve the same. What you could do however, is add in Cagrilintide and that should be the appetite suppression you're looking for.
