Octreotide vs GHRP-2
A detailed comparison to help you understand the differences and choose the right peptide for your research goals.
Octreotide
Octreotide (Sandostatin) is a synthetic somatostatin analog FDA-approved for acromegaly, carcinoid tumors, and VIPomas. It inhibits growth hormone and various GI hormones.
Full details →GHRP-2
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 | Octreotide | GHRP-2 |
|---|---|---|
| Mechanism | Binds to somatostatin receptors (primarily SSTR2 and SSTR5) to inhibit GH, glucagon, insulin, and gastric secretions. Reduces blood flow to GI tract and inhibits tumor hormone secretion. | 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 | Varies by indication. Acromegaly: 50-100mcg three times daily initially, up to 500mcg TID. LAR (long-acting): 20-30mg IM every 4 weeks. | Typical dosing: 100-300mcg administered 2-3 times daily. Often stacked with GHRH peptides for enhanced GH release. |
| Administration | Subcutaneous injection for immediate-release (between meals). Intramuscular for LAR depot form. Requires monitoring of gallbladder, glucose, and thyroid. | Subcutaneous injection on an empty stomach. Can be used at bedtime to enhance natural GH pulse during sleep. |
| Side Effects | GI effects (diarrhea, nausea, abdominal pain), gallstones (up to 25% of long-term users), injection site reactions, and blood glucose changes. | Moderate hunger increase, water retention, potential prolactin and cortisol elevation (less than GHRP-6), tingling sensations. |
