well, 150mg of pstanz for 6 weeks is most likely not going to put on 3-5lbs of muscle, unless you are one of the few who respond well to low dosages.
when I ran pstanz with pro dienelone (ams dienedrone) I had 2 bottles, and ran it at 300mg during the 4 weeks of dienedione, and did not experience any extra gains than when I ran dienedrone solo.
but, I also did not experience any of the gyno related side effects when i ran dienedione solo.
this however should be noted as anecdotal info, and even considered educated bro science.
but....
winstrol, the methylated version of prostanozol, does have data showing it to bind to the progestin receptor, without having any interaction, blocking it, much like a serm blocks an estrogen receptor.
this is also most likely the cause of the hardening & drying out users experience from winstrol, and also (unknowingly) why it's been a fav to stack with other nor androgens such as trenbolone.
oh, and one more thing, pstanz is not a prohormone, nor does it convert into anything.
It is a fully active androgen with a 3-keto group the only difference between winstrol and pro stanozol is winstrol has a 17a methyl group attached (at the 17a position), and pro stanozol instead has a thp ether group attached on the 17b hydroxy part of the steroid.
