he is correct. dienolone, like trenbolone, because of it's structure, is difficult for the liver to breakdown, causing stress.
the main difference with the transdermal dienolone and the oral dienedione (pro dienolone) is bio availability. the skin is limited in how much it can absorb, where the gut is unlimited.
so one can dose 90, 120, or more mg of pro dienolone, where they can not dose as much dienolone transdermally.
but mg for mg, the hepatotoxicity is the same and one should expect elevated liver enzymes from usage of the product.
