Just came back from my physical, doc found gyno in my right pec! Asked if I was taking any supplements, and told him about the Nortesten i was taking over the summer. He said he was about 100% sure that's what did it to me. DAMN YOU MUSCLE TECH, I HATE YOU! Luckily, it's not that big of a condition yet only 1/2 an inch...but it's still gyno. Stay away from muscle tech for pro hormone product bros, just letting you guys know.
