What is your opinion on doing short cycles?I read an article and some bodybuilding dude swears by them,he says doing a cycle for about 4 weeks at small enough dosages gives you gains (of between 5 to 7 pounds for example) that you keep and side effects are minimum. My side effect worry is keeping my hair and would like to know what was your experiences on doing short cycles? Sustanon causes hair loss but on a 4 week cycle would it have a negative effect on the hair?
