Ok, I am an endurance racer....80mi+ non stop races. . Please help, what should i take.. Power to weight ratio is impt.. no water retention, not looking for huge weight gains. I have EIA ( excersise induced asthma) and took Masteron 4 months ago and it totally wiped it out.. made me super lungs.. but I also want a big libido kick.. Over 40 and want some more drive. Didn't really get that with 100mg a week of the Masteron. Dont really want to take over 200mg a week of anything. Taking cyp. now and big mistake. Sweating like crazy,moody,water retention.. So, lean, power, endurance, good carb synthesis.

Thanks for your help and ideas.
