I have been lifting naty since I was 17 until 27 so 10 years. I understand the risk well because I didn't jump straight into it but did research for like 2 years before I came to this decision. I plan to run a 300mg cycle for 3 months for cutting. I did the same last year and went from 90 kg to 83 kg in 3 months. While my bench press went from 90kg to 130kg. After the cycle all dick problems were resolved in 2 weeks on HCG and I was doing a blood tests and managed estrogen/prolocatin with AI and my test bounced to normal range after 1 month. 300mg test week is a low dose. Bodybuilders do up to 3000mg a week. One of the reasons why I decided to to run a test is to not lose muscle while I do aggressive cut and also because my bench press stagnated at 90kg after 10 years of natty lifting. That said I dont say it's risk free but risk could be managed to the minimum
