If Roman has used 800mg to 1200mg per week for five weeks and he has NOT GAINED A POUND OF MUSCLE, the problem is the gear not the diet. At 1000mg per week of real test, you feel it kicking (muscle growth, pumps, strenghts, ect) not matter what you eat (slight exageration here to prove a point).
I have used Brovel test enantate on several occasions in the past years. My experience with it, and with pretty much all mexicain products, is that I FELT that the concentration of active ingredient per mg varied greatly from one vial to another. I noticed very good gains some of the time and little other times. The exception being ttokkyo and denkall, who's products I believe are of consistent quality.
I don't have any lab test results to show, I speak from my personal experience only.
Not too long ago I tried the prop from Loeffler (bought from a reliable granero in TJ). I shot a full 250mg of prop. Nothing. I am still waiting for the gains to come.. This is from a guy who feels some growth the day following a sostenon shot...
