GHRP-2 vs Dihexa
A detailed comparison to help you understand the differences and choose the right peptide for your research goals.
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 →Dihexa
Dihexa is a nootropic peptide derived from angiotensin IV. It has shown remarkable cognitive-enhancing properties in animal studies, being described as potentially millions of times more potent than BDNF.

| Aspect | GHRP-2 | Dihexa |
|---|---|---|
| Mechanism | 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. | Acts as a hepatocyte growth factor (HGF) potentiator by binding to its receptor c-Met. Promotes synaptogenesis, neuronal survival, and cognitive enhancement through this pathway. |
| Typical Dosage | Typical dosing: 100-300mcg administered 2-3 times daily. Often stacked with GHRH peptides for enhanced GH release. | Research dosing is highly variable due to extreme potency. Typical range: 10-40mg orally or sublingually. Start with lowest doses due to potency. |
| Administration | Subcutaneous injection on an empty stomach. Can be used at bedtime to enhance natural GH pulse during sleep. | Can be taken orally, sublingually, or intranasally. Extremely potent - careful dosing is essential. Best used cyclically. |
| Side Effects | Moderate hunger increase, water retention, potential prolactin and cortisol elevation (less than GHRP-6), tingling sensations. | Limited human data. Reported effects include headache, temporary brain fog during adjustment, and potential mood changes. |
