Does anyone know if Primo will elevate your prolactin or progesterone levels enough or at all to cause Gyno? I ask because of its similarities to Deca.
Im pretty sure ive never heard of anyone getting gyno from a primo only cycle, unless the dosage is just massive. im sure someone will disagree, but i would think you would have to be extremely suseptable to getting gyno in the first place. A good clue would be if you had it bad as a teen going through puberty. if not then dont even worry about it.
Primo lacks a carbon atom at the 19th position of its structure,therefore aromitase has no CA to remove and alter it's structure(into an estrogen molecule).It has no inherent progestogenic or prolactic activity.
I'm just coming off a primo only cycle 300 mg's per week in and somehow a lump has formed under my right nipple any suggestions it looks terrible and my nips protrude
If it's gyno from a primo-only cycle,then your primo was counterfeit.I would start hitting some liquidex if I were you to down-regulate estrogen production.
i beg to differ. primo wont give you the big gains of test or tren, but you get virtually no sides at all. once you pay your dues and put on some size from the hard shit, cycle primo and get the little extra edge of an aas, without the bullshit.
you have to stack the heavy androgens for your first few cycles, but then, primo is the icing on the cake.
that sucks bro,its probably test prop! still at 300mgs and half life is only a few days, yeah the counterfits have been around a few months,sheringen stopped production,spain is still up!
