75mg/day is PLENTY. You will be more than happy with the results as long as everything else is good. You should worry more about resting enough with your work hours than the juice. That will make more of a difference than thinking it's OK to slack and bandage it with AAS use.

Personally I think it sounds like you are shortcutting with gear. You're too lazy (by your own admission) to get up to a weight you've already been to, so you wanna juice and get past it. Obviously you are doing something wrong if you can't get back up to a weight you've been at naturally.

Sorry to be harsh, but this ain't a game- it's your body and you're altering its chemistry. Taking a big step such as this requires prudence.
