A SERM will maintain LH/FSH and some degree of baseline T production, which depends on the testes.
Clomid [steroidal] has nasty estrogen side effect for some, recommend non-steroidal Nolvadex.
SERM dose should be low, 10mg or 10mg/EOD, just enough to maintain the testes and scrotum. If SERM pushes LH too high, one can get high E2 levels from T–>E2 inside the testes and AI cannot control that.
No one seems to think that a life time of SERM is advisable. hCG is a natural hormone.
SERMs do nothing to decrease E2, they only shield SELECTED tissues from the effects of E2. Only an AI will reduce E2.
Your vitamins will list the fillers, which can be yeast or some other ‘natural’ material.
