Suddenly confused about some numbers

My Urologist finally prescribed me 180mg/week of test Cypionate, and stated the dose as 0.9ml. Does that jive with 180mg per week?



Post your pre-trt labs?

TT, FT, estradiol, SHBG.....CBC (which includes hemoglobin/hematocrit).

I would rethink starting off on 180 mg T/week.

Such dose will most likely have your TT/FT level too high let alone the downfall of injecting once weekly is that your peak TT/FT/estradiol levels will be sky-high post-injection (8-12 hrs)/elevated during the first few days only to be followed by much lower levels come weeks end .

There will be a big difference in peak--->trough level and blood levels will not be as stable throughout the week which can have a negative impact on energy/mood/libido/erectile function.

Top it off that use of exogenous T will increase your hemoglobin/hematocrit.

More sensible to start low and go slow as you have absolutely no idea how your body will react to testosterone.

100mg T/week split (50 mg every 3.5 days) would be a good starting point.

Most men can easily achieve a high-end let alone absurdly high FT on 100-150 mg T/week.....and yes even men with highish/high SHBG.
 
Agree with madman and Systemlord. If you start with a high dose and encounter many side effects, it will discourage and frustrate you. And, you might overshoot the so called 'sweet spot' where you feel good and have improved sexual function.

I do plan to split that dose. Thanks

Post up your labs: TT, FT, estradiol, SHBG let alone CBC (includes hemoglobin/hematocrit).

Definitely a smart move but again 180 mg T/week let alone split twice weekly (90 mg every 3.5 days) is too high a starting dose off the hop!

Again most can easily achieve a healthy (high-end) let alone absurdly high trough FT on 100-150 mg T spit twice weekly.

Start low and go slow.....100-120 mg T/week split twice weekly (50-60 mg every 3.5 days) would be a more sensible move.

Understanding Your Hormones

Estradiol (E2)

A form of estrogen produced from testosterone. Important for bone health, mood, and libido. Too high can cause side effects; too low can affect well-being.

DHT

Dihydrotestosterone is a potent androgen derived from testosterone. Affects hair growth, prostate health, and masculinization effects.

Free Testosterone

The biologically active form of testosterone not bound to proteins. Directly available for cellular uptake and biological effects.
