Primo is not hair safe.
It acts like an aromatase inhibitor in most guys lowering estrogen.
Low estrogen will kill your hair.
Not knowing this, I ran 600 test 500 primo for a while last year and my hair stopped growing.
I knew my estrogen was low bc my sex drive went down to just average.
Masteron acts like a serm, doesn’t lower estrogen just blocks effects at the receptor, so should be hair safe IF YOUR ESTROGEN IS NORMAL RANGE.
Now I am on 600 test 800 mast and 62.5 primo. No AI except primo.
Hopefully will have good news to report about hair. Waiting on labs.
You got that info from doc Todd lee and his crew right?
He says never run primo higher than test because it will crash your estrogen, and he says to run it one to one at most which you nearly did and it still crashed your estrogen so thanks for.sharing this info brosef
He also recently said that if you use deca run it with zero test
Vigorous Steve will be dropping a deep dive on deca real soon
Watched a vid on a classic physique BB and he will be running 400 test and 800 primo so that will probably crush his estrogen but maybe his genetics will allow him to do so without crushing his estrogen
So you are using 62.5 primo as an ai?
And a gram and a half of gear is a decent sized cycle
