I have been doing cyp at 500mg for about 8 weeks. My results have only been mediocre. I just bought 30 amps of sustanon. I also still have 15 ml of cyp and 15 ml of enanthate. I am planning on staying on through summer. (right or wrong) My question is. Do i start the sustanon or continue with the cyp for a couple more weeks. My gains have really started to slow down. Recommendations???
