As you said, it's all dependent on what the bloodwork shows. I just think it's asinine to make blanket statements as presented in the article without recognition that everyone is different. It would have been nice to see an acknowledgement that it actually takes seeing what your bloodwork shows in order to help determine the right dose.
And, I'm a perfect example of someone who hypermetabolizes/has very low SHBG and needs a relatively high dose to maintain just decent levels. When I first started TRT (prescibed) roughly 15 years ago, I was on 250mg of a blended testosterone. With bloods pulled just 4 days post-injection, my total test was 860, the upper end of the reference range.
Over the past couple years I've had to adjust my dosage more than a few times, getting bloodwork as often as every other week while tweaking said dosage. A few months back, 260mg/wk (split dosing of 130mg Mon and Thur) had me in the mid-600 range. I more recently switched to Mon, Wed, Fri injects (80mg each to start) which put me in the low 700's. I've since upped the dose to 90mg 3x/wk and will get bloods again in a couple months.
