recently in mexico i picked up 50 vials of sten(2ml each), plenty of nolvadex and plenty of clomid. alot of websites say to take between 2 and 4 vials a week. how long should i stay on a cycle for and at what dosage? should i start with a small dose and build up and then back down or should i stay at the same amount throughout? i'm 200 pounds,5'10", 10% body fat and have been working out for about 4 years. and one last thing, will this stuff show up in a urine test? i'd appriciate any advice. thanks.
