I chose to go with Generic Labz Mega-H because of the amount of information I was able to find on this board and over at the forums on bodybuilding. I had the same dilema. I found plenty of good reviews and good user feedback regarding not only the quality of the product, but also it's effectiveness. The one theme that seemed to run through every thread was that most agreed that halodrol clones are best run for 6 weeks because at weeks 3-4 is when gains are in full force. Mega-H is cheaper too compared to Hemadrol. Mega-H is roughly $30 for 90 caps, and each cap is 25mg. Hemadrol runs around $40 or so.
I'm currently 12 days into a 6 week Mega-H cycle. I'm dosing it at 75mg. What I noticed in the first 7 days was a slight boost in libido, a harder erection, increase in appetite, and the beginning of all day muscle pumps. Around day 8 or 9 is when I started to notice a heightened alpha male attitude kick in, and now at day 12 I'm starting to notice some increases in muscle mass and vascularity. I've noticed that my irritability level has gone up once I do get irritated, but I'm not moodier or quick to snap. No acne, no hair shedding, no oily skin. Blood pressure is fine. I'll be adding 4mg of Mega-TRN next week.
