Yeah the pheromones come from the metabolite called ———— which is a hormone that comes before testosterone I think it comes from dhea, so my theory is that if androstenedione is responsible for pheromones testosterone would lower pheromones since it shuts down everything before it. Unless test can somehow be converted back to AD. Not too sure exactly because I’ve read lots of reports too from people saying they notice stuff. I had the hormone wrong these are the two.
Androstadienol and
androstadienone are odorless compounds secreted by the
apocrine glands, and via conversion into the more powerfully-odorous
androstenone and
androstenol (catalyzed by
aerobiccorynebacteria, particularly
Corynebacterium xerosis, in men, and
Micrococcaceae spp. in women), are considered to be mainly responsible for the "musky" component of
axillary (underarm)
odor.
[1][2][3] Androstadienol is
synthesized from
pregnenolone by the 16-ene-synthetase activity of
CYP17A1,
[4] and is converted into androstadienone by
3β-hydroxysteroid dehydrogenase.
[5] Male sweat contains approximately five times as much androstenone as does female sweat, which can be explained by
sex differences in androstadienol and androstadienone
This is why it’s hard to believe this because these are synthesized from pregnenolone. If pregnenolone is shut down on cycle then it wouldn’t produce these metabolites unless somehow testosterone can be broken down back into these.
Androstadienone, also known as
androsta-4,16-dien-3-one, is an
endogenous steroid that has been described as having potent
pheromone-like activities in humans.
[1] The compound is
synthesized from
androstadienolby
3β-hydroxysteroid dehydrogenase, and can be converted into
androstenone (a more potent and odorous pheromone) by
5α-reductase, which can subsequently be converted into
3α-androstenol or
3β-androstenol (also more potent and odorous pheromones) by
3-ketosteroid reductase.

Idk the entire hormone map and all the pathways and enzymes or we would have an answer.
