Hi everyone. Excited to join the forums and be a part of this community. After years of feeling many of the typical symptoms of low T (the cognitive symptoms and low libido in particular), I have finally taken the step of doing something about it. I'm 46 and over the last several years I've watched my T levels go from the mid-200s to 168 on my latest labs. I've always been in good shape and have eaten pretty healthy, but with a big family and pretty demanding job I have struggled to manage stress and have not slept as well as I should. I'm working on those areas and hopeful that along with TRT I will see a significant improvement in overall quality of life. An improved physique to go along with it would be great as well.
Fortunately, I've found a local PCP willing to work with me on this. He's been very open to structuring and adjusting protocol based on my goals, preferences, and physiological response.
He's suggested started with 80mg Test Enanthate injected subQ weekly and work from there. No AI until we see labs or if I start showing signs of high E2. He also recommended holding off on HCG since I have no plans for more children but is willing to add it at any time if we feel necessary. Dosage seems a little low, but I'm willing to start small and work up from there.
My one question around this is whether I'd be better going to every 3.5 days but will probably see how weekly works first. Doc didn't feel it was necessary since I was doing subQ.
Anyway, as I said, very excited to be on this journey and look forward to being a part of the forums.

Welcome!
The best piece of advice is to start low and go slow.
100 mg/week would be a good starting point especially when jumping on once-weekly injections.
Smart move starting on a T only protocol let alone avoiding the use of an AI as we want to see how your body reacts to testosterone and where said protocol (dose T/injection frequency) has your TT, FT, estradiol, DHT levels let alone other blood health markers such as CBC which includes RBCs/hemoglobin/hematocrit.
Keep in mind that testosterone metabolites
estradiol and DHT are needed in healthy amounts to experience the full spectrum of testosterones beneficial effects.
Having healthy estradiol levels is needed as it will have a positive impact on mood, energy, libido, erectile function, cardiovascular/brain/bone/immune system health, body composition.
Even if your estradiol ends up being high which is a given if you drive up your T levels you may very well feel great.
Some men do need to use an AI (micro-doses) to control e2 but it comes down to the individual and is not a given.
The addition of hCG can be added eventually if you want to prevent/minimize testicular atrophy let alone maintain fertility while using exogenous T.
My one question around this is whether I'd be better going to every 3.5 days but will probably see how weekly works first. Doc didn't feel it was necessary since I was doing subQ.
Although some men will do well injecting once weekly many men on trt tend to inject more frequently as in twice weekly (every 3.5 days), M/W/F/, EOD, or even daily.
Keep in mind that when injecting once weekly that there will be a significant difference in peak--->trough especially when injecting strictly IM let alone blood levels will not be as stable throughout the week which can result in having a negative impact on one's mood, energy, libido, erectile function, recovery throughout the week.
If you plan on once-weekly injections strictly sub-q than peak--->trough may not be as extreme let alone blood levels may be more stable throughout the week.
Even then I would be more concerned with where your SHBG sits as not only will it have a significant impact on free testosterone but can also dictate what injection frequency may suit you best.
If your SHBG is high/highish then you may fair well using once-weekly injections especially if you inject strictly sub-q.
In cases of low/lowish SHBG, a more frequent injection protocol (EOD/daily) may be needed.
Comes down to the individual and what works best.

MP85-14 VARIANCE IN PEAK AND TROUGH TESTOSTERONE LEVELS IN MEN USING INTRAMUSCULAR TESTOSTERONE Bruno Nascimento*, Helen L Bernie, Elizabeth Schofield, John P. Mulhall, New York, NY INTRODUCTION AND OBJECTIVES In men using intramuscular testosterone (IM T), clinical experience shows us that...

CONCLUSIONS: In our population of patients on
stable IM T dose, there was a wide mean variation in both Tp (23%) and Tt (17.5%). In addition to that, 25% of patients had a maximum Tp change greater than 50% and a maximum Tt change greater than 35%. Clinicians should be aware of this high variability in levels when deciding on dose adjustment.
