I used Test charge for 3 cycles when i first started doing the Reeves program. The last 2 months on the reeves was all me. I do think that my levels started dropping toward the end of my 5th month and that could be why I was starting to struggle with the weight on 12 reps.
This is going to be atleast a 2 month cycle as I bought 2 kits while it was deal of the day last week. I may run a 3rd cycle if I see great progression bulking, dont want to lose it over not buying a 3rd kit. Though it seems to keep levels elevated for a couple months after the cycle ends.
