in the case that he is 21 or older nobody said t-bol which is a good compound for strength and endurance from what I have read. never taken it myself though.
From a cyclst myself trust me, test.eth is the best use only a max of 150mg per week this will bring test. Levels high but keep water retention in check. High doses of anabolics will kill an endurance athlete. Taking low doses will help in recovery and this allowing you to train harder.
