HGH Fragment 176-191 vs Pramlintide
A detailed comparison to help you understand the differences and choose the right peptide for your research goals.
HGH Fragment 176-191
HGH Fragment 176-191 is the fat-reducing portion of the growth hormone molecule. Unlike AOD-9604 (which has an additional tyrosine), this is the exact fragment of HGH responsible for lipolytic effects.
Full details →Pramlintide
Pramlintide (Symlin) is a synthetic analog of amylin, FDA-approved as an adjunct to insulin therapy in type 1 and type 2 diabetes. It helps control post-meal blood sugar spikes and promotes modest weight loss.

| Aspect | HGH Fragment 176-191 | Pramlintide |
|---|---|---|
| Mechanism | Mimics the lipolytic region of growth hormone, stimulating fat breakdown and inhibiting lipogenesis without affecting blood sugar or promoting growth. Works independently of GH receptors. | Mimics amylin's effects: slows gastric emptying, suppresses glucagon secretion after meals, and promotes satiety through central mechanisms. Complements insulin therapy. |
| Typical Dosage | Typical dosing: 250-500mcg daily, often split into 2-3 doses. Usually administered on empty stomach, often with fasted cardio. | Type 1: Start 15mcg before meals, titrate to 30-60mcg. Type 2: Start 60mcg, may increase to 120mcg. Always with meal containing 30+ grams carbs or 250+ calories. |
| Administration | Subcutaneous injection. Best results when used fasted and combined with exercise. Avoid eating for 30 minutes post-injection. | Subcutaneous injection immediately before major meals. Must reduce mealtime insulin by 50% when starting to prevent hypoglycemia. Never mix with insulin. |
| Side Effects | Generally well-tolerated. May cause injection site irritation, temporary lethargy, or headache. Does not affect blood glucose significantly. | Nausea (very common initially), headache, anorexia, vomiting, and abdominal pain. GI effects typically improve over time. |
