My personal experience, I love primo, I’m about to run test e, primo e, var, hgh, on a trt dose right now, 160mg a week of test, taking 2iu a day of growth, im lean as can be, eat what ever i want, but to answer your question, primo i would run 400mg a week, for along time, 20 weeks, it gives you that 3D look, almost like anavar but a lot better, it doesn’t give u any real side effects that I’ve noticed. I used to run tmt, (test,mast,tren) but the side effects was terrible, if you do research Arnold and Ronnie Coleman ran primo, primo if your body fat is low, is gonna make u vascular, ripped, lean, I wish years ago I new about primo, just because the side effects there isn’t any besides looking great. I’m not a fan of 19- nor derivatives, Big fan of dht derivatives, hope that helps u in some way brother, if u wanna be ripped with a 6 pack, primo, test, HGH but several kits, 10 I would say, it’s all what your wanting to achieve if you want a lot of size go with a 19- nor, I stay away from compounds that make me aromatize, I go for the lean beach body look!
