Description
Lypholized powder needing reconstitution.
HGH Fragment 176-191 (also studied as AOD-9604) is a synthetic 16-amino-acid peptide that represents the tail end of the human growth hormone (hGH) molecule. It is widely investigated in research for its ability to stimulate fat loss (lipolysis) while bypassing the growth-stimulating and insulin-disrupting effects of the full hormone.
Mechanism of Action
- Targeted Fat Loss: Scientists propose that this specific fragment contains the “lipolytic” segment of hGH. It selectively triggers beta-3 adrenergic receptors, which regulate fat burning in both white and brown adipose tissue. [1, 2]
- No Muscle Growth/Anabolism: Because it is truncated, it does not promote muscle growth or alter blood glucose metabolism, making it a distinct area of study from full-length hGH
