Every HGH Fragment 176-191 listing, cheapest per mg first
Sticker prices hide the size, so listings are ranked by what a milligram actually costs — with independently tested purity where it exists. All 14 are here: the last 3 are listings whose vendor never published a strength we can read, so they have no per-mg figure to sort on.

Real $/active mg divides the price-per-mg by the measured purity — the honest cost of the actual peptide, so a 90%-pure vial isn’t compared as if it were 99%. Too cheap? flags a listing far below the market rate — often underdosing or a fake, not a deal. The crown marks the cheapest non-outlier; best value marks the lowest real cost per active mg. A vendor shown as Unavailable or Low stock is priced here but not currently buyable.
Understand this compound
What is HGH Fragment 176-191?
Preclinical / animal onlya.k.a. HGH Frag 176-191 (AOD-9604 is a related, modified analog)The 'fat-burning tail' of the growth-hormone molecule — a small piece studied for whether it can trigger fat breakdown without the growth effects of the whole hormone.
Good to know: Human evidence is extremely limited and effects are modest at best; it is not an approved drug and the quality of research/grey-market material is unverified.
How does HGH Fragment 176-191 work?
The science
The unmodified C-terminal fragment (176-191) of human growth hormone; proposed to trigger lipolysis via beta-3 adrenergic receptor/cAMP-PKA activation of hormone-sensitive lipase, without GH-receptor-mediated growth or IGF-1 effects.
Mechanism of action from published research — how the molecule behaves, not a claim about any product or any human-use effect.
What is HGH Fragment 176-191 researched for?
Studied for fat loss/lipolysis, attempting to isolate GH's fat-burning action from its anabolic and diabetogenic effects.
- Weight & metabolicStudied in weight, appetite, blood-sugar, and fat-metabolism research.
How far has the research gone?
Preclinical / animal research; effects are documented mainly in rodent studies, with only small, inconclusive human trials.
Where the science stands — an approved drug is not the same as the research-grade material a vendor sells, which is unregulated regardless.
What should I check before buying?
- Independent purity. Look for a third-party COA (Janoshik or MZ) showing a measured purity — not just a number the vendor typed.
- Batch match. The strongest evidence is a certificate for the exact batch you’ll receive, attributed to this vendor — check the cross-verification on the listing.
- Vendor reputation. See how the vendor is talked about in the community before trusting a new name.
Research context only — VialGrade never gives dosing, medical, or human-use guidance.
The lab evidence
What we could verify
Each row is a separate question with its own answer — one green row never vouches for the rest.
Identity
PartialThe vendor advertises third-party testing; no independent record confirms it yet.
Measured purity
UnknownNo independent purity measurement on record.
Batch traceability
UnknownNo batch on this listing matches an independent record.
Sterility
Not testedA purity certificate doesn't measure this — no such test on record.
Dose accuracy
UnknownNot something VialGrade measures — no test on record.
testing advertised, but not independently confirmed
This listing advertises testing, yet no independent record in our index references Core Peptides for HGH Fragment 176-191. That doesn't prove the certificate is fake — but until it resolves at the lab, treat the testing claim as unbacked, not verified.
- Vendor claim. Advertises testing.
- Independent confirmation. No record found for Core Peptides. Verify the certificate at the lab before trusting it.
Cross-checks the vendor’s testing claim against independent lab records. Read from the certificate, not re-measured by VialGrade. Purity is not a grade. Never a statement that a product is safe, sterile, or correctly dosed. What “grade” actually means

Research-use-only — not FDA-approved
Sold “for research use only,” this compound is not FDA-approved for human use and has not been evaluated for safety, purity, or sterility in people. It is generally not a scheduled controlled substance, so buying it as a research chemical is typically not itself a drug crime — but marketing or using it as a drug is not lawful, and it is not a dietary supplement.
General information, not legal or medical advice. VialGrade sells nothing and encourages no human use.
