I have a friend who swears that he gets more looks from women while on tren. Anecdotally, many people seem to report this. I have several hypotheses about why this is so:
(1) Tren ace increases sex drive. It's possible that he's projecting his own increased libido on the women around him.
(2) Tren ace tends to make guys "cocky", the sort of alpha behaviour women like.
(3) Guys usually shed a bit of fat on tren, giving the chiselled jaw look.
(4) Tren is highly androgenic, giving a "rugged" appearance
(5) Tren might push a guy who's a 5 or 6 into 7 or 8 territory.
Of course, my friend could just be delusional. Also, if you're a 1 in attractiveness, I doubt tren or anything else will make you more attractive; as they say, "you can't polish a turd"
