So I have extensive experience with Deca only and Tren only cycles. I had a lot of trouble with test and AI's out of the blue. So I started doing just one compound, I read many many study's on the compounds. I never had any issues doing these cycles for years and years. Then suddenly I had horrible prolactin issues on my last one. Pulled some blood work and my E2 was none existent. I never went over 400mg deca or 300mg Tren. In my opinion 2g of deca is about 1600mg to much and is just asking for trouble. I never have trouble with recover and most times I don't even run a PCT. of course I am pulling blood work if anything ever changes I will go back to the more standard PCT protocol. I don't advocate this type of cycling though. I think you need to run At least HRT levels of T. It just so happens with my particular situation with side effects and such, running T even in lower dosages caused sides to be pretty unbearable even with ancillaries.
