Let me tell you something I am 30 years old and have been cycling on and off for 5 years. 1 cycle a year for the past five years. I started my first cycle at 25 because I didn't want to fuck myself up at a young age. I was always a thin as dude growing up, always wanted to be bigger. Waited until 25 then hit my first cycle. A quad test. I didn't know what I was doing but still enjoyed it. I had to learn the hard way with my first two cycles not using an ai and no pct. So its just friendly advice to try to diet and train naturally at your age. Everyone wants to be big, but at what cost?
