The optimum length for most people cycling SuperDrol is 2 to 3 weeks because that's when strength and mass gains seem to top off for almost everyone. The effects on the liver are very mild as far as toxicity. The effects on lipids are dramatic. Even for a two week cycle it's recommended to run cholesterol support products before, during and after all the way through pct. Using something like policosanol, or even better Red Yeast Rice with CoQ10 for cholesterol support is a must. Plenty of logs have been kept on this compound over at anabolicminds.com.
Cholesterol numbers return to normal very quickly with use of the proper products. There were even a few logs with blood work dedicated to tracking this particular variable. Most people kept their gains and were very, very happy with the product.
There are sporadic reports of gyno on SuperDrol. However, most of the ones I've read involved a number of things which are wrong such as: inadequate PCT, as in none; stacking with 4AD or some other 'wet' product without a SERM or AI; gyno coming up to eight weeks after usage and proper PCT, but being blamed on SuperDrol even though other substances were being used, anything from high dose tribulous to dianabol.
I'm very skeptical about gyno concerns with SuperDrol. It can definitely happen, but I seriously doubt the likelihood is higher than any other AAS, and probably lower than most.
