环戊丙酸睾酮是合成代谢雄激素类固醇（AAS），是具有与睾酮类似功能的合成物质。

GIP receptor antagonist (IC50 = 2.6μM). Inhibits GIP-stimulated insulin release from pancreatic β cells in vitro. In ob/ob mice, blocks the effects of GIP on insulin release and plasma glucose levels. Also improves intraperitoneal glucose tolerance, insulin sensitivity, and glucose response to feeding in ob/ob mice.

Endogenous truncated form of the incretin hormone GIP. More potent at stimulating glucose-dependent insulin secretion from rat pancreatic β-cells than GIP.
