They are two totally different compounds, yet they compliment each other greatly.
Androstenetrione (
6-oxo) is the most important for pct for bringing hormone levels back to normal, however the effects
7-oxo-dhea has on cortisol levels greatly helps during pct and adds fat burning effects.
Metacort is the best out there since it has both compounds with the added benefit of topical application, and at the same price, if not less, than
6-oxo alone.
