Human growth hormone (HGH).

Naturally found within our bodies, HGH has demonstrated efficacy in lowering body fat, leading to weight loss. AOD-9604 is an analogue of human growth hormone (hGH) 177-191, meaning that it is manmade and similar both structurally and functionally to hGH2. Several studies have evaluated how AOD-9604 affects the body in the context of weight loss.

Troches are a medicated lozenge that easily dissolves in the mouth. This route of administration makes it easier for medications, like hormones, to enter the body by entering directly into the bloodstream. It allows the medication to work quickly in the body while also avoiding metabolism by the liver. 

None of this matters because AOD9064 - naD+ is no longer available. I cannot say I noticed much of a difference over the six months I was on it.
