I havenāt read your entire thread, but I think part of your problems with libido come from being on too high a dose for too long. When you hear about guys feeling great on blast or high TRT dosages, itās typically not sustainable. Youāre catching them when theyāre feeling good and posting about it. Chances are if you checked on them 6 months later, assuming they kept blasting the whole time and they were honest with their feedback, they probably arenāt feeling so good anymore.
There might exceptions of course, but the human brain isnāt built to function optimally with Test levels at 5x the range. Thereās evidence that supraphysiological Test levels are neurotoxic and over time through oxidative stress lead to a loss of Dopamine neurons, something you probably want to avoid.

Depending on what youāre trying to achieve, I think experimenting with lower dosages might resolve some of your issues.
Thereās also evidence (clinical research) that shorter esters lead to less suppression of the HPTA than longer esters, which is one of my theories as to why some seem to feel a lot better on Prop.
If your number one priority is to get massive while completely disregarding long term health and longevity, then a drop to 140mg/week is going to be noticeable, but you might be surprised how much better Prop works than Cyp in a lot of ways. It doesnāt look from your pics like youāre trying to be absolutely massive, and personally Prop at 105mg/week for me blew 160mg/week of Cyp out of the water as far as body comp, strength and water retention. And Iām not the only one with that experience.
It seems youāre somewhat concerned with your health long term, and I donāt care what anyone says I promise you running 300mg/week of Test for decades will fuck you up, no way around it. People arguing otherwise just want to justify permablasting. Which is fine, everyone should do whatever they want, I donāt care. But if youāre expecting to not suffer negative consequences from doing that, youāre in for a bad surprise.
Prop hits fast and hard because the half-life is so short (~20 hours). Some people do IM and like it that way, personally IM left me feeling a little too amped up and wired for my taste, despite feeling great otherwise. SubQ seems steadier while retaining most of the benefits of IM.
Besides libido, Prop gives me the best mood by far and best workouts, pumps, and drive in the gym. Iād try both IM and subQ, but I would start with subQ and see how you feel.
