Pramlintide vs GHRP-2
A detailed comparison to help you understand the differences and choose the right peptide for your research goals.
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.

Growth Hormone Releasing Peptide 2 (GHRP-2) is considered one of the most potent GHRPs available. It provides strong GH release with moderate hunger increase compared to GHRP-6.
Full details →Side-by-Side Comparison
| Aspect | Pramlintide | GHRP-2 |
|---|---|---|
| Mechanism | Mimics amylin's effects: slows gastric emptying, suppresses glucagon secretion after meals, and promotes satiety through central mechanisms. Complements insulin therapy. | Binds to the ghrelin receptor (GHS-R) to stimulate GH release from the pituitary. Also has some direct effects on the hypothalamus. Causes less appetite increase than GHRP-6. |
| Typical Dosage | 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. | Typical dosing: 100-300mcg administered 2-3 times daily. Often stacked with GHRH peptides for enhanced GH release. |
| Administration | Subcutaneous injection immediately before major meals. Must reduce mealtime insulin by 50% when starting to prevent hypoglycemia. Never mix with insulin. | Subcutaneous injection on an empty stomach. Can be used at bedtime to enhance natural GH pulse during sleep. |
| Side Effects | Nausea (very common initially), headache, anorexia, vomiting, and abdominal pain. GI effects typically improve over time. | Moderate hunger increase, water retention, potential prolactin and cortisol elevation (less than GHRP-6), tingling sensations. |
