Hi Kajun,
Methenolone acetate (primo) is my favorite AAS. I have done 3 cyles of it and did very well on it. VERY mild sides even at dosages that gave nice strengh and size gains. Seems like we are all different, some girls i am finding bloat on primo. Average muscle gain each cycle was 5 pounds. (after lifting for so many years these are fantastic gains). You may be better if it is your first cycle.
Are you to use it in a cutting or building cycle? I used last cycle 25mg ED of Schering S divided into three dosages. Primo is not 17AA so about half of it is deactivated by the liver as it enters the blood from your small instestine, so the actual dosage is about 12mg each 24 hours.
There are a lot of primo fakes in amerika so be careful. Check the counterfiet board.
