- In the GHRP-2 vs GHRP-6 comparison, cortisol and prolactin profiles are often cited as differentiators — but published data suggests the cortisol difference is less meaningful than commonly assumed. The Ghigo et al. (1997) study found comparable ACTH and cortisol responses between GHRP-2 and related hexapeptides at standard doses. In the GHRP-2 vs GHRP-6 comparison, both compounds produce moderate, dose-dependent cortisol elevation that generally remains within physiological range at standard research doses (100-300mcg).
- Prolactin elevation shows a slightly clearer difference in the GHRP-2 vs GHRP-6 comparison: GHRP-6 tends to produce somewhat higher prolactin elevation at equivalent doses, consistent with its broader receptor activation profile. However, both compounds’ prolactin effects are typically transient and normalize between doses. For researchers where cortisol and prolactin confounding is a serious concern, Ipamorelin ($39.99 at PSPeptides) provides the selective alternative with negligible effects on both hormones.
