Doc Wants to Change Dosage of Test C

Hi all, hoping for some feedback. Have been on 200mg/week test c(pinned 100mg every 3.5 days) for about 6 months now. I feel fantastic, best I’ve ever felt. Bloodwork mostly looks fantastic, as well – I’m low SHBG, so this dose has my peaks around 850 and troughs around 650. Free test a little high @ 31.

The only areas of concern in bloods are estradiol and prolactin are a little high, at 52 and 26* respestively(labcorp values). Doc wants to get those down, so he’s telling me that he wants me to drop to 160mg/week.

I’m worried as hell. I currently feel better than I ever have. The only negative side effect I’ve seen at all is water retention. I read about other low SHBG guys struggling to have a good TRT experience, and dropping by 20% overnight is going to get my trough values down close to my pre-TRT fasted morning peaks. Am I overreacting here? Am I overworrying for nothing? I really don’t want to feel like I did before TRT again for months.

EDIT: Mistyped prolactin

@anon18050987 can you plug that into your little calculator? This seems to be really odd based on the 1) low SHBG and 2) your estimated 1.4x multiplier peak/trough when injecting e3.5d. The peak seems really low I guess is what I’m getting at

Without units or ranges for the PRL, I’m assuming that’s about 3x the upper limit? Lowering your dose 20% isn’t likely to move that down enough; I’d investigate why it’s that high to begin with. Maybe it’s elevated cos e2 is elevated, and taking an AI would be more beneficial for both?

The upper range for Labcorp for prolactin is 15.2.

Pre-TRT:

TT, fasted morning peak: 308 ng/dL
TT, trough: 209 ng/dL
FT not tested
e2: 22.3 pg/mL
Prolactin: 10.3 ng/mL
SHBG: 18 nmol/L

Post-TRT:
TT Peak: 840 ng/dL
TT Trough: 627 ng/dL
FT Peak: 31.7 pg/mL
FT Trough: 27.9 pg/mL
SHBG: 10.9 nmol/L
e2: 57.1 pg/mL
prolactin: 26.2 ng/mL

Currently 6’0, 220lbs, ~34" waist

A lot of men on TRT typically run higher on the estrogen. Prolactin is controlled by two hormones, dopamine and estrogen, both of which are affected by testosterone.

CBC all normal range, RBC only thing that’s not smack in the middle of the range @ 5.56 x10E6/uL

Lipids all also excellent. Don’t have results handy from that, but no issues on that.

I suppose that’s fair. I’m just super concerned because everywhere I look, I see other low SHBG guys struggling to have positive results on TRT, and I’ve had stellar results since I started. Afraid that dropping my dose by 20% is going to lead to me feeling like shit and then spending months trying to get to somewhere close to where I am now physically and mentally.

That’s going to be a common occurrence on these TRT boards, men having problems and seeking help. The men not having problems are continuing with the lives with no need to visit a forum.

I have low SHBG, 12 last time I checked and feel great.

Still pretty close!

Ok yeah that’s what I thought. Some go up to 20ng but wasn’t sure

Interestingly, elevated BP and RHR were symptoms of my low T. RHR is down by 15 since I started TRT, and my BP went from 150/90 to 130/80. No other changes except TRT.

Just out of curiosity, what’s your dose and where are your peak/trough levels?

Jatenzo @ 237 mg twice daily, peak 998 ng/dL at 2 hours, 298 at 12 hours. HCT 51.2%, HGB 17.5. I don’t tolerate cypionate and enanthate esters injecting every other day or daily, which are the only two protocols for which I respond to therapy.

Jatenzo is very expensive, $3400 per 12 weeks without insurance. Most insurance companies will not pay for it, unless you get a medical exception from a doctor.

A new oral testosterone undecanoate therapy comes of age for the treatment of hypogonadal men

Thanks. My insurance won’t cover anything beyond my appointments unless I have multiple tests below 200ng/dl, so definitely wouldn’t prefer to jump into something like Jatenzo.

It’s stories like that that make me nervous, though – my 100mg every 3.5 days has been great since day 1. Hopefully this doesn’t derail me, but I’ll trust my doc I suppose
