umm...i've said this before, i was at your stats 6'3'' and a measly 170. did my first cycle of winny alone and regretted it. I was a hasty and thought I knew it all. my point, you can gain weight naturally, just eat like a horse, then when your ready, take the plunge. for the nolva... it all depends really, I would run nolva thruought the cycle if I were you. thats just me tho
