Ok, I started my first cycle with this in mind. I am a college swimmer, and I did a simple test e at 500 mg/wk. For a total of 12 weeks, I've only ever been piss tested so I'm fine. But I will tell you in swimming I get painful shoulder pumps when swimming very long distance days but not on sprint days. Also anavar if you get it legit then it can also cause painful pumps. I was lifting and eating a ton while I swam and gained about 16 lbs! A great majority being muscle since I was doing so much cardio and this slowed me down. So, I'm no expert but from what I've experienced, it would be good to get something that won't give you as bad as pumps as it hurts during practice. I could suggest like low dose test (250 mg/wk), eq, and maybe low dosages of anavar to avoid the pumps or winny. Again I am not a pro on this but trust me you want to avoid those painful pumps! And not gain too much weight as it will slow you down.
