What is HGH Fragment 176-191?
Plain language first. The technical label stays, but it never stands alone.Overview
It aims to target stubborn fat without the rest of growth hormone's effects, but real human evidence is thin.
HGH Fragment 176-191 is the tail end of the growth hormone molecule, the part linked to fat breakdown.
What it's used for
People use it to try to target stubborn fat. Real human evidence is thin.
How does HGH Fragment 176-191 work?
What it does in the body, and where.The fragment is the last section of the growth hormone molecule, residues 176 to 191, isolated because that region is associated with fat breakdown.
- 01It copies the fat-releasing region onlySignaling fat cells to release stored fat, without the rest of the growth hormone molecule.
- 02It does not raise IGF-1So the muscle-growth and blood-sugar effects of full growth hormone do not follow.
- 03The human evidence is thinAnimal results were encouraging. Trials in people, including on its close relative AOD-9604, did not reproduce them.

What else is it used for?
Each use below carries its own evidence level. Approved means regulators have cleared it for that purpose. Investigational means it is in trials. Early research means it is being studied and is not established.

- Fat loss without raising IGF-1, which is the claimed advantage over growth hormone itselfEarly research

How much, and do you cycle it?
The range, and whether you take breaks.0.25 up to 0.5 mg per day (start low, increase slowly), daily. Studied as daily dosing for up to 12 weeks Trial dose
The same molecule as AOD-9604, given daily for up to 12 weeks in the obesity trials with no cycling and no benefit over placebo.
Not establishedCommunity practice
Never studied in humans. The 15 to 30 minutes quoted online is borrowed from AOD-9604, which is a related but different fragment.

How do I dose and price it?
Enter your vial and your dose. Pick a mix. We show the draw and the cost.The vial holds a fixed amount of drug. Adding more water does not make more drug, it just spreads it thinner, so you draw a bigger number on the syringe for the same dose.
Choose your mix
Measuring the water1 mL = one full 100-unit syringe.

How do you store it?
Before mixing, and after.Dry powder in the freezer or fridge. Once mixed, fridge, and use within about a month.
Unmixed lyophilized HGH Fragment 176-191 keeps for a long time cold. Once you add water the clock starts: most reconstituted vials hold up for roughly 28 to 30 days at fridge temperature. Keep it out of light, and do not freeze it after mixing.
What are the side effects and cautions?
Known cautions and warnings for this compound.Solubility, computed: 33% charged residues, 47% hydrophobic. Water usually sufficient.

What regulators say
From official documentsProhibited at all times, in and out of competition. S2.2.3 growth hormone fragments, e.g. AOD-9604 and hGH 176-191. Non-Specified.
Checked 12 September 2026WADA: The 2026 Prohibited List (in force 1 January 2026)
Banned in drug-tested sport. Most research peptides are prohibited under WADA's S0 category, which covers any substance with no approval from any regulatory authority for human use. That means a compound can be banned without ever being named on the prohibited list. Check with your own anti-doping authority rather than assuming absence from the list means permitted.
