I've tried the 500mg test cycle and i didn't gain nearly as much until I hit the 750 range. Obviously there's 250mg more, but with the 500mg cycle, only gained around 14 pounds, then my last cycle of 750 and some Ds at the beginning, I gained almost thirty, and kept in the mid 20 range, huge difference. I got one buddy who takes one 250mg shot of omna a week for 10 weeks and puts on 15 pounds and his stregnth goes through the roof. He does this every couple of months, it's crazy. My diet is really good, in fact it's too good right now. My metabolism is through the roof. It's sick, i miss a meal or snack/meal, and my stomach goes ape shit! I see my body weight drop if I'm not on top of it everyday. Sucks eating that much everyday.
