Hi there, I assume you were doing testosterone enthante as well? Most people report it takes 4 weeks to "kick in" so 20 lbs in 5 weeks is very good. I'm suprised you managed to keep the gains as there would have been water retention presumably if you weren't running an anti-aromatizer during the cycle, and you didn't run any PCT. I would expect my gains to not be as high due to no water retention and I basically lost a week ill. Having said that, in the last 6 days I have gained 4.5 lbs so on the assumption the gains continue at that rate I should gain a fair bit by the end of the cycle. I'm pretty happy with the diet side of things and workouts are generally 45 minutes long which is the recommended duration. Most exercises are to failure so I don't think thats an issue. Having said that, you could be genetically gifted - I wouldn't say I was :-)
