For example, if you're running 500 mg of test E per week, two weeks after the last shot you'd have the equivalent of 250 mg test/week in your system (assuming a two week half life), and after four weeks you'd have 125 mg, etc.
But, if you're running 1000 mg test E per week, you'd be at 500 mg after two weeks, 250 mg after four weeks, and 125 after six weeks.
Thus, it would seem that when you start PCT (and/or how long you run PCT) would depend not only on the half life of the gear, but also the dosage. Also, I'm wondering if it makes sense to start PCT when your blood levels are at, say, the equivalent of 250 mg? Since a typical test replacement level would be right around 125 mg/ week or so, it seems you could start PCT once you reach that level without losing much mass, etc.
Also, I'm not sure it makes sense to start PCT if your blood level is still at the equivalent of 250 mg test/ week because that would still be quite supressive of natural test production, and it seems that nolva, etc. would not be very effective if you still had that much exogenous test in your system?
I'm coming off a cycle of 500 mg test E and 400 mg deca per week. I'm wondering if it would make sense to wait a full four weeks (or more) to start PCT because there would still be about 125 mg test E and 100 mg deca in my system at four weeks. Any thoughts? Am I missing something here?
