i’m glad people are getting something out of this… i am by no means an expert, but have been able to track some data that seems to clarify things quite a bit.
anyway, something else i thought might need to be mentioned is why PCT can’t be rushed.
when we’re waiting for the ester to clear the body, it doesn’t just take a couple weeks. test e/cyp has a half-life of 4.5 days, but that simply means that it is half the dose 4.5 days after injection. for the sake of planning, we will just assume that it has the half-life of a week.
if you’re ran test e for 12 weeks at 600 mg, the final week you wouldn’t just have 600 mg in your body-you’d have just under 1200 mg, due to the ester build up (600+300+150+75+37.5 etc etc). now, once we stop administering a dose, the blood levels drop pretty quick, but you wouldn’t be below 1 mg of exogenous test until 10 weeks later.
the most an adult male is gonna produce of test is 10 mg/day, or 70 mg/wk. so with that being said, we can’t expect our HPTA to kick back in until it’s at least below that level. and since we know that any amount of an exogenous hormone is going to cause suppression, we have to continue with the SERM until the vast majority of that is out of the body.
so in this case, blood levels of test are gonna hit 74-ish on week 16. i would add in the SERM at this point, and continue taking it until we are down to 1 mg or so (week 22, in this case). this will allow the SERM to increase our own production as the outside test is slowly tapering out. now the nice thing about Nolva is, we know that it’s still effective for 6-8 weeks. tore isn’t quite as effective as nolva, but it does work longer (12 weeks), so it’s a great option in longer cycles.
i know for me, i tend to screw up the math, so i just plug it all into an excel spreadsheet and go from there…
hope this helps!
