I have been using SYN products for about 8 months now.
Dbol, var, test e/c/u, tren A, all legit and mint af. Ralox seems solid too.
Now let's talk their Ai,. If anyone remembers Deus, i hated everything they had, did not like the source or the product - the opposite is true for syn, but there is one exception: AI. For months i have been just at war with high e2 and its sides, popping adex and asin like tic tacs from these guys - NOTHING. Well i had some old deus asin sitting around and in ONE dose all those sides are gone, nips zero sensitivity, the ralox is nuking the tiny bit of gyno. This came as a shock as deus was (in my mind) basically discredited and syn is the gold standard, but this is my experience with their ai. I do not know if it is a bad batch or old/expired/loss potency, or if this is what is expected, but this batch of syn ai may as well be sucrose.
ALSO JUST TO REITERATE: EVERYTHING ELSE SYN I HAVE TRIED IS GOOD TO GO.
