They say it's not risky because effects will be localized, however the study I linked to states it has 100 times less affinity for AR than dht itself but it converts into dht in the body somehow. So if it is dht heptanoate, as you said, it will take time to convert to dht and so the only benefits one can see would be from systemic effects and increase in dht, the opposite of what thew advertise for. As always, I don't know anything about biochemistry so carry your pinch of salt when you read my posts but from the little I see their claims make no sense.Yes I noticed this as well. It would be a slow conversion to DHT then as enanthate sticks around for a while I believe. Might take a week or two of supplementing to notice an effect? If it's in DMSO it should absorb into the body, whereas normally with an ester it wouldn't.
