Total T vs. Bioavail T

Pharma
1

Right now I’m on 140mg/week of TE.

I inject subQ daily (20mg/day).

I feel fine, Total T is 24.0 nmol/L (10-28 ref. range)…in range

But, Bioavail T is 12.24 nmol/L (2-8.6 ref. range)…quite high

Is this a issue I should be concerned with?

Is there a reason that at this specific dose, one parameter would be in range and the other would be rather high?

This says it all. Free T and bioavailable T ranges and testing are poorly established.

Your SHBG could be low

4

Yeah, on the lower end, but in range.

21.2 nmol/L (14.5-48.4)

5

Any specific reason for this? Seems like an unnecessary pain with a slow release ester.

6

Probably just being unnecessarily cautious.

Prescription is for 140mg weekly injection.

I wanted to avoid any possible highs/lows.

I find subq more appealing than IM.

Subq is marginally easier (I’ve done both landed on IM in the end) but I’d say injecting X2 per week is ample (X1 would probably be fine). Presumably its 200mg/ml so moving from 0.1ml daily to 0.35ml x 2 per week shouldn’t really impact the injection site, but less faff for you.
