Description
hGH Fragment 176–191 (also called AOD-9604 or tyr-hGH 176–191) is a synthetic 16-amino-acid fragment corresponding to the lipolytic C-terminus of human growth hormone, with a stabilizing tyrosine substitution at the N-terminus. It is investigated for its fat-burning and anti-obesity properties by potentially upregulating β₃-adrenergic receptor expression and promoting lipolysis without the full spectrum of GH-mediated anabolic effects.

FAQ
1. What are research peptides?
Research peptides are short chains of amino acids used in scientific and medical research. They are not approved for human consumption or therapeutic use but are studied for their potential biological effects.
2. Is Reverse Peptides a trusted source for buying peptides online?
Yes. Reverse Peptides offers 99% purity, third-party tested, and USA-made peptides. Our products are backed by quality assurance and a loyal base of researchers
3. How do I store research peptides after receiving them?
Most peptides should be stored in a cool, dry place. Lyophilized powders are typically stable at room temperature but should be refrigerated for long-term storage. Always refer to the product label.
4. What payment methods do you accept?
We accept major credit/debit cards and secure online payment options. All transactions are encrypted and secure.
5. Is a prescription required to purchase peptides from Reverse Peptides?
No. Since our peptides are sold strictly for laboratory research purposes, no prescription is required. However, buyers must be qualified researchers or institutions.
