Metabolic / fat loss

hGH fragment 176-191 (modified)
Research-use-only / grey market Notable unknowns

Status & caution. Not FDA-approved (a food-ingredient pathway was explored but it is not an approved drug). Named in the 2026 reclassification discussion but NOT among the 12 peptides FDA advanced to PCAC review; sold grey-market as 'research only.' Marketed as 'fat loss without GH side effects,' but human efficacy trials were largely disappointing.

At a glance

Molecular formula
C₇₈H₁₂₃N₂₃O₂₃S₂
Molecular weight
≈1,815.1 g/mol
Sequence / structure
C-terminal fragment of growth hormone (residues 176-191) with an added N-terminal tyrosine; a disulfide-bonded fragment.
Regulatory status
Research-use-only / grey market

Indications & what it's studied for

Promoted for fat metabolism/lipolysis without the IGF-1 rise of full GH; also explored for cartilage/osteoarthritis.

Contraindications & cautions

No established human contraindications; no approved drug use.

Commonly reported dosing

Reported, not recommended. The following describes what appears in research literature and community use. It is not a protocol, and unapproved peptides have no validated human dosing.

Community use reports small daily subcutaneous doses; efficacy is not well supported.

Routes of administration

Subcutaneous injection; oral forms marketed.

Don't combine with

No characterised interactions documented.

Reported to stack with

Sometimes combined with GH secretagogues for body-composition goals.
Note: "stacking" combines multiple agents and multiplies unknowns; popularity of a combination is not evidence of its safety.

What the research actually shows

Human obesity trials did not show meaningful weight loss versus placebo at tested doses, a key reason for scepticism.
