yer it would increase ur recovery ..ive read some people say that they dont even get sore on cycle - personally i still get sore but i dont think as sore.. if ur a sprinter you would want to stay away from steroids like tren and ancilliries like clen or dnp (not that it sounds like u would be ne where near doin dnp but using it as an example lol) cos they can severely hamper your aerobic capabilities... i no its the case for athletes like footballers and tennis players because there more endurace but im guessing it would also have to affect sprinters... happens from a variety of reasons .. some gear can alter the oxygen in your blood or red blood cells or somethin .. some make your blood thicker (DNP) .. i no tren is pretty bad for aerobic endurance any one else shed some light on sprinting? depends what your wanting to acheive - id prob say test prop - but the pain from prop in the legs might make running unbearable. I no i inject in legs and cant run for abotu 3 days - im a footballer ... your best bet would prob be anavar cycle so you wont have to worry about injecting - var is ****in expensive tho and the results dont really match its price but its pretty safe as far as orals go ( none are really that safe) if u did want crazy strength gains without the mass you could do halotestin but that shits pretty nasty... dont even think about doin a winstrol only cycle - once again you wont be able to run but thats cos ur joints will turn to drywall
