The vast majority of guys on TRT, whether it be through a TRT clinic or underground, use 150-200mg injections once weekly. Pharmaceutical companies have done studies which indicate there are 600,000 men on TRT through doctor sourcing. I would not be shocked if there are another 600,000 on testosterone through black market sources, no way to know for sure though. Big Pharma would love to increase the dose (sell more product), but will need research to get that approved through the FDA and with generic and compounded products available, the money is not there because they can’t get patents on a dose. Instead, they work on fancy, more elaborate delivery methods, such as a silly autoject pen.
Point being, there are hundreds of thousands taking once weekly, or even twice monthly, dosing and doing fine. What you see here on the internet are outliers, overly focused on their levels, being “stable”, their estrogen, etc. Not that these issues are irrelevant, note I said “overly” focused. Walk around all day worrying about your moods and your nipples will lead you the find a problem there.
I will allow for some guys who are overly sensitive to hormones, but they are few and far between. These guys will talk of 200mg as a “massive” dose. Having competed in weightlifting in the high octane PED days of the '70s and '80s, I find that laughable as 200mg would be a baby dose (and consider that would be stacked on top of other injectables and orals) used by novices and guys in the lighter weight classes.
As for you specifically, the prescribed dose is ridiculous. I would not even bother to start with that dose. As systemlord mentioned, you should find a TRT doctor, or BHRT doctor, a practice that only does hormones.
If I am you, given your labs, I’d start with 200mg per week. I think you could start with 150mg if you’d like and if happy there, stay. Like over 90% of the guys on TRT, you’ll do fine with once weekly. It’s always interesting to hear others’ results and protocols. Injecting more often won’t hurt you, I just doubt you’ll need it. I’m actually surprised someone hasn’t tried twice daily injections. Keep in mind testosterone levels vary as much as 140-200ng/dL per day in normal guys.
For reference, my last labs had me at 906 total, 213 free, 51 E2 and SHBG of 21 taking 200mg once a week.
Good luck, you’re a perfect candidate for TRT and should obtain great results. You’re going to wish you did this ten years sooner.
