i dont completely agree with this, just because it does not aromatize doesnt mean it wont cause gyno specifically in the case of DHT derivitives.
I agree. Also, Superdrol and Epithio's are very dry compounds which leads me to believe that they may actually decrease estrogen when on cycle.
Normally, some test aromatizes into estrogen via the aromatase enzyme. Superdrol shuts down natural test and it doesn't aromatize. Shut down means little to no test production, which means whatever estrogen a person had due to the aromatize enzyme decreases (as their is no test to aromatize due to shutdown). This would decrease total estrogen when on cycle.
The body likely increases aromatase in an attempt to normalize estrogen and balance out the exogenous anabolic. This could cause a massive rebound of estrogen when superdrol is discontinued and natural testosterone production begins. I think this is the cause for reports of delayed gyno with superdrol. (ie: influx of natural test + unnaturally high aromatase enzyme)
Delayed gyno wouldn't happen with something that aromatizes, such as test or D-bol. You could still get gyno, but it would likely show up on cycle rather than after. Using a dose of a-dex or letro every other day with an aromatizable compound is probably not a bad idea. But is probably pointless with Superdrol.
I think it is very unlikely he can reverse pubertal gyno at age 21. He might reduce some swelling in the tissue, but it is likely anchored in pretty good. At best, it may shrink from a larger, softer mass - to a smaller harder one.
Just my thoughts on the subject. I may be completely wrong. I am not an endocronologist and these are just my opinions.
