When do you reach TRT saturation?

[BackToRegular]

At what week does one reach TRT saturation (when your serum blood level doesn't increase from week to week)? Is it dose dependent? I ask not only because I'm curious but also this will help guide when to get my first TRT bloodwork.

Depends on the ester, but it takes 5 half lives to reach your stable point I think. For Cyp that’s about 5-6 weeks

Thanks swoops36; math checks out: (5*8)/7 = 5.714

To keep the math simple, assume that you take a dose of testosterone on its half life day. That is if the half life is 7 days, then you take a dose every 7 days. Then the amount of testosterone in your system is

1 dose after 1st dose.
1 + .5 = 1.5 after 2nd dose
1 + .5 * 1.5 = 1.75 after 3rd dose
1 + .5 * 1,75 = 1.8725 after 4th dose
gradually approaching 2 doses at the limit.

The formula is (2 - 0.5 ^ (n -1)) where ^ denotes exponentiation and n is the number of doses.

I start to feel the full effects by 5.5 weeks., this is when stuff starts picking up.
