If you ever get to a point where you start losing the benefits of TRT, the protocol your doctor put you on would be the reason. If you’re at 800 on day 7, the second half of week 2 you have low-T.
Also, injecting one very large dosage may have consequences, like driving up your hematocrit, hemoglobin and estrogen levels that may or may not cause problems.
One large infrequent injection doesn’t offer a lot of control and typically lacks any sort of consistency in the way one feels. Most members inject weekly or more often.
Please don’t make the assumption your doctor knows what he’s doing, between outdated guidelines written by unqualified people, a lot of doctors are operating in the dark for what is a new field of medicine, one that isn’t taught in mainstream medical schools.
I thought your refractory period of a few days was bad, I don’t know how anyone could be worried about an improved refractory period. Also, you’re probably still in the TRT honeymoon phase, the body will find normality down the road.
