I believe the weight gain part wether or not it was all muscle is another question.
The strength gains I have a hard time buying however I personally know someone who gained roughly 20pds off a 4 week M1T cycle. his gains were actually very lean. strength goes up quite a bit on m1T also.
Yeah he gained the weight, all water and fat. you know as well as i do that you cannot pack on 15 pounds of muscle in 4 weeks.
my first test/dbol cycle i gained 40 pounds and i would bet only 5 of that was muscle tissue.
i've taken M1T and it did increase strength but it's not that great, shit i've had about 15 college kids take the stuff while i trained them and their gains were "ok". not a single person on this earth could make the gains this guy claims, it's genetically impossible.
i've studied the human body more than 90% of the people on this site and i know what the fuck i'm talking about. it really gets old having all these new guys come on here claiming all this bullshit.
