12 weeks?
I go in 4 week intervals myself, but doses are higher.
I use C/E so about 4 weeks for then to be concentrated in the blood, constantly keeping my body adapting to the increase as to not plateau.
No scientific backing, just how I do it.
I disagree about the "no scientific backing" You analyzed and applied some known data to the question, that's scientific. I'll drop some numbers that may be of interest. The drop info might be useful for various things including figuring PCT for those folks.
A typical peak plasma level curve for a Test E 500/week cycle (214 E3D). At much higher or lower levels the curve changes buy not by too much if staying in the "sane" dosages.
1 week to reach 64% of saturation
2 weeks to reach 90% of saturation.
7 weeks to 99.9% of saturation.
Sudden cessation of cycle after staying at saturation level for at least 2 weeks
After 1 week 34% of saturation.
After 2 weeks 12% of saturation. Roughly between 6-700 ng/dl, a decent level for some for TRT
*After 3 weeks 4% of saturation. Roughly 200-250ng/dl.
After 16 weeks 0% of saturation from exogenous test. That doesn't mean you have zero plasma T though, hopefully your have started to recover some natural production sometime after week 2.
*It takes 3 weeks to be at fairly effectively zero level of Exo T no matter the dose if staying in the "sane range" which is probably anything under a gram or maybe even a gram and a half.
I didn't realize no one tappers lol. Guess I should read more posts more often
Lot's of people do, myself included. Don't judge anything to critically by this kind of small sample size. Even if every member here or for that matter on every board on the net answers a question that's still a small sample size of all the users.
I do it myself sometimes. Personally I implement increases based on a minimal drugs that give maximal effect attitude - The min dose needed before the return curve flattens out. Further I need to be able to justify any increases - has my training and nutrition been good enough to demand an increase? Will I be able to use the additional amount before getting into that flattened curve area where the AAS isn't really doing much extra. I coach it the same way, important to remember that I've never really been a contest prep coach. That is a whole different ballgame.
Usually ups would be looked at around every two weeks. And even though people will say there is no need because "the ester does it" I like to come back down to TT dose by lowering something like 100 per week. Less shocking, more time to adapt even for non TRT guys. In the old days tapering off was used in place of PCT which wasn't a thing yet. A long slow taper works pretty good for recovery as your body picks up production at a certain point and you still have an exo T base. Might be a little less comfortable than modern PCT, but you've avoided some pharmaceutical stress, suck it up Nancy.
