Great experience with osuk as always. My order was Pharmaqo Primo 100 and Pharmaqo masteron 100 which I combined to my adelph testosterone that I also get from them. Quality is always great. I didn't have many side effects although I took a very small dose so keep that in mind with side effects. Dose obviously has a lot to do with that. As far as some side effects Pip wasn't bad. I noticed sometimes i'd feel nothing and other times i'd be quite sore. I have heard primo causes some bad pip so it was probably from that. I didn't get too bad of acne a little bit but not bad. Libido was really good, which was probably the masteron. I've heard that is one of the benefits and for me it definitely had me chasing my wife around the house. Energy was good, mood was good, focus was good, sleep was good. Really not a lot of side effects. Blood work was good, my estradiol was low without an AI, Test was high (for a low dose) No complaints at all. I was running 250 mg test, 100 mg mast 100 mg primo. Only thing i'd change about my experience is in the future I might increase the dose a bit.
