Kodac, you have injected 1-test?
It sure burns like molten lead!
About 4-hydroxytest, it has about the same properties as 4-chlorotestosterone aka clostebol. This is a kick-ass steroid with 0 estrogen and DHT conversion, resulting in hardness and quality muscle. Of course, the oral availability is very very poor.
BTW, 4-hydroxyandrostenedione aka formestan is a powerful suicidal aromatase-inhibitor, which again only works IM. For some reason you can buy it an netrition.
