The advice and practices I am now seeing in this forum are horrible. The fact that is has not [yet] crippled some guys is not the determining factor. The issues re high dose hCG and high dose SERMs was resolved here around 8 years ago and that perspective has been lost. More is not better and more can be harmful.
hCG or SERM use during a cycle should stimulating LH receptors at levels that normal LH lab range. If you expose LH receptors to high levels of LH, hCG or LH+hCG then transition to normal LH levels [if you are lucky] post PCT, what do you expect your testes to do with this huge LH or LH+hCG level drop? It can only be bad.
SERM doses should not be high. 100-50mg is totally stupid. I am not here to make you feel good about this. 20mg SERM EOD is probably all that one needs.
High dose SERM or high dose hCG leads to high T-->E2 inside the testes. And your competitive AI anastrozole is ineffective inside the testes and serum E2 can be way out of control. Never stack SERM+hCG. Your end of PCT can expose the HPTA to that residual E2 and down it goes. Your SERM only protects "Selected" tissues from estrogens, the others are awash in estrogens that limit gains, energy and libido. E2 management is critical and SERMs do not negate the need for decent E2 management; which is impossible with high dose SERMs or hCG.
The SERM tapers from insane doses to lower misses the whole point of the taper. The taper allows T and estrogen levels to drop so the HPTA does not see high negative feedback after the SERM is no longer hiding estrogens from the hypothalamus. SERM taper should be tapering slowly down from 20mg EOD. You need to avoid estrogen rebound, not just go through the motions.
While managing E2 levels with a AI during PCT, you need to manage E2 levels post PCT. 0.5mg anastrozole per week in divided EOD dosing should do a good job and cruise on that, tapering out after a few weeks. This will reduce any estrogen rebound tendencies.
If you have gyno, the problem is too much estrogen, not a need for high dose SERMs.
More is not better, more is stupid. PCT is not a suicide mission.
