How to calc Cyp to scrotal cream doses?

I (54M) am currently taking 130 Test Cyp a week but want to try scrotal cream to see if it is better at improving libido symptoms. Currently 130 TC/wk (split 3x) puts me at about the right overall level (trough TT at 1000, free T at 25, E2 sensitive at 34). But I don't want to switch entirely, I want to move to a split protocol.

So here's what I was thinking- if one click is .25 ml and it's a 50 mg/ml cream, then that's 12.5 Test per click. At a 50% absorption rate that 6 mg Test absorbed per click. 130 mg/wk injected is 18.5 mg/day of TC. I think TC is about 70% Test so that's 13 mg Test/day. So if I wanted to start with a split protocol adding one click a day of cream that means I can cut my TC injections by half (to say maybe 70 mg/wk)?

Do I have that math right? Has anyone done anything similar?

If you have an idea of how you absorb you could get a better calculation. But you don't know that yet so you're taking a shot in the dark.

I would use the half of a normal shoulder dose and look from there. Since your bloods will stabilize in days you can dial it in pretty fast.

there are two studies about transscrotal application:


scrotum appl. is 5-8 times stronger than normal skin sites

If you want to replicate a trough TT of 1000 with a 20% cream, try 2 clicks AM and 2 clicks PM and see where that get you 12h after application.
