Question 1

What is HGH Fragment 176-191?

Accepted Answer

Synthetic 16-amino-acid peptide corresponding to the C-terminal region (residues 176-191) of human growth hormone, stabilized by a disulfide bridge between its two cysteine residues. It was developed at Monash University (Australia) to isolate growth hormone's lipolytic activity: it is reported to stimulate fat breakdown and inhibit lipogenesis while lacking the growth-promoting and insulin-antagonizing effects of full-length GH, since it does not meaningfully activate the GH receptor or raise IGF-1. It is not FDA-approved for any human indication and exists as a research/grey-market compound; the related Tyr-modified analog AOD-9604 failed to meet primary endpoints in an obesity clinical trial.

Question 2

Which vendors sell HGH Fragment 176-191 with independent COA testing?

Accepted Answer

6 vendors in the Merit Verified directory have independent COA evidence on file for HGH Fragment 176-191 — 7 COAs total. COA coverage and test dates are listed on the HGH Fragment 176-191 page at https://meritverified.org/peptides/hgh-fragment-176-191.

Question 3

How do I verify the quality of HGH Fragment 176-191 from a vendor?

Accepted Answer

To verify HGH Fragment 176-191 quality, look for an independent certificate of analysis (COA) from a third-party lab — not a lab the vendor owns or pays directly. The COA should state the tested compound, lot number, purity percentage (identity and concentration), and the lab's name. Cross-reference the lot number against the vendor's current stock. Merit Verified indexes COAs for HGH Fragment 176-191 at https://meritverified.org/peptides/hgh-fragment-176-191 so you can compare evidence across vendors before buying.
