TweetHow long you been on. Sometimes your SHBG will rise with exogenous test use. SHBG attaches to the "binds" to free test making it pretty much useless until metabolized and it never gets to exert itself on the androgen receptor (AR). Then there is down regulation of androgen receptors when using even moderate doses of test over time. The body senses it has very high test and slows production, hence your testes shrink. This state CAN reduce sensitivity of the AR in the body. Hormones are really complicated.
Are you using any anti Es? Strong stuff like aroma will kill sex drive.
Try coming off 8 weeks. Do a standard PCT with nolva then go back on.
Also there are supps to help with SHBG. Supplement with Boron, magnesium, Stinging nettle extract, avena sativa, and D3. The first 2 are minerals most folk are deficient in. The next two are herbs that have compounds with an affinity for SHBG, they bind to it leaving more free test in theory. Last is D3 which is a vitamin over 75% of people in the USA are deficient in.
