Yes, this is my second second time using it, I've put on almost 10 lbs of lean mass. For a long time I was stuck not really making gains. I'm over 40 and been training since 99 and using anabolics since early 2000's so gains come slower. I was stuck between 220-230 lbs last year around this time. This morning I woke up 246lbs and still as lean. I use 2-3mg daily, my tendon pain improved, recovery is better and definitely muscle growth. I recommend using it with GH and on a.a.s. for maximum growth. Feel free to ask more questions if you'd likeOkay guys, anyone out here been using infrajet? Really interested on your thoughts
