I did a six week cycle of Super One + (4-ad, 1-testosterone) and I took saw palmetto, nettle root extract and pumkin seed. For external use a used nizoral shampoo, minoxidil and spironolactone. Yeah, I was concerned about my hair thinning, but it didn't happen.
As far as feeling lethargic, I seem to feel that way on and off it. I guess it might have something to do with staring at a computer all day. I feel drained a lot times when I get home, but I just continue to hit the weights. I don't like to miss a workout because it makes me feel like I'm getting weaker.
