Completely agree. I was running a high test cycle an all of a sudden lost my sex drive. Went from 100 to 0 - but I had my estro in check. I added hcg 3X per week and it shot through the roof. So when I started trt I just decided to run it all the time. Its relatively cheap and easy to pin. I dont plan on ever dropping it.
A lot of guys say they think it drives their estrogen high. I swear it levels out my hormones to a good balance though. Doesnt cause me to increase a.i. at all and as you said - seems to increase my mood. I've been preaching this stuff for the last year - especially when the alternatives are drugs like clomid. A large majority seem to have issues with that crap.
Btw loss of libido on test with estro in check in my case was due to prolactin. Sh1t was 50% above top of the range.
That being said, currently running mk677 which completely killed my libido. Took caber and it solved my sore nipple but increase in lbiido was meh...nothing special.
But as of beginning of last week i am on hcg only, no test whatsoever, and this week i increased hcg since it is the last week of hcg before coming off.
Libido is freaking high, despite me using mk677. So it must be the stimulation of lh receptors.
Test never really raised my libido unless i used caber alongside. Masteron neither (since i got masteron from a sketchy source some have suggested that it was tren and that would explain low libido and high prolactin but that is whole another topic).
2 things that have substantially raised my libido are hcg and 6 bromo.
