I did not read all this but when it comes to P we mean P4 which is natural Progesterone and not synthetic versions of it.
One thing we must remember is that genetic woman has good hair growth when they are young and far less when they get older is due to P4 and not to any of the other Estrogens. So ONE important factor is that P4 is the most perfect antiandrogen available and it blocks DHT better than any other medications.
If you really want to test these facts just do this; Talk to your Doctor about Utrogestan. Measure your T, P4 and DHT by your doctor. Take one capsule before bedtime (don't eat anything at least 2h before). On the 10th day you stop taking Utrogestan and then repeat your blood tests. You will then see something unbelievable.
I've done this several times as part of my HRT and for a study made by my endocrinologist and it's clear that P4 should be part of any HRT.
For breast growth I'm not so sure that P4 works because we can't conclude that we really got Progesterone receptors in M2F breasts so argumentation for taking P4 or not should solely be based on if it's the best DHT blocker or not because that is easy to prove and ANYBODY can so easily test and prove these facts BUT be aware that P4 is also an anti-oestrogen agent so if you take P4 also your E2 will drop and that's why you should not take this more then 10 days of the month.
Hope you like these facts ...
