Sorry bro, I’m not questioning you but do you understand these terms in pharmacology and how it affects how biology in humans? I just want to know if you understand as I can go off tangents
if not all good.
Mast works more like a SERM, acting on E2BR and E2AR binder as a negative agonist , hence the word “mast” meaning mast cell, working as an anti prolific agent in breast tissue.
Primo was made for different reasons as an anabolic agent for babies and women with muscle wasting disease, they found testosterone virillised in children and women and needed something more towards non- aromatisation and something they can use in infants, so they removed BA from it as well so it can be tolerated (hence why pharma primo has massive PIP) also has shown its use originally in anaemia patients which is interesting,
I’ll be doing a write up soon of primo vs mast from a clinical point of view and it’s Pharmacology and chemistry, and use in bodybuilding anecdotally and what they both do at a cellular level. Hopefully it clear the confusion up for the two, problem is bro, there aren’t enough studies in Anabolics. If they are, they get quickly pulled by pharma companies.
