Fragment 176-191 is a synthetic peptide that consists of amino acids 176 to 191 of the full-length human growth hormone (HGH) molecule. This modified sequence retains the fat-burning properties of HGH while eliminating the growth-promoting and blood sugar-altering effects. As a result, it offers highly targeted lipolytic activity without the potential side effects associated with full-length HGH.
HGH Fragment 176-191 stimulates lipolysis (the breakdown of fat) and inhibits lipogenesis (the formation of new fat), making it ideal for users seeking accelerated fat loss—particularly in stubborn areas—without affecting muscle mass or insulin sensitivity.
Benefits
-
Targets and accelerates fat loss

Especially effective on abdominal and stubborn fat areas
-
Does not raise blood sugar or insulin levels
-
No impact on muscle growth or organ enlargement
-
Non-androgenic – safe for both men and women
-
Enhances body definition and supports cutting cycles
Side effects
HGH Fragment 176-191 2mg is well-tolerated and considered very safe. Possible side effects may include:
-
Temporary irritation or redness at injection site
-
Mild headaches
-
Fatigue or dizziness (rare)
-
Increased hunger in some users

How to administer – reconstitution and injection
Reconstitution:
-
Mix 2mg vial with 1ml of bacteriostatic water
-
Inject the water slowly down the side of the vial
-
Swirl gently (do not shake) until fully dissolved
Injection:
-
Use a 1ml insulin syringe
-
Inject subcutaneously into abdominal fat or other fatty tissue
-
Dose reference (with 1ml reconstitution):
-
250mcg = 12.5 units
-
500mcg = 25 units
-
Storage
-
Before reconstitution: Store the vial in a refrigerator or cool, dry place
-
After reconstitution: Refrigerate at 2–8°C and use within 30 days
-
Do not freeze. Protect from direct sunlight
Half life & detectability
Half-Life: Approximately 2–3 hours, making split daily doses more effective
Detection Time: Not commonly screened in standard drug panels, but may be detectable for several days in advanced hormone testing
For athletes subject to drug testing, it is crucial to consider these detection times to avoid positive tests for banned substances.
