CJC-1295 / Ipamorelin vs MK-677
Both are discussed for muscle & performance and anti-aging & longevity. What this site records about each, side by side. Every figure is on the compound's own page with the source it came from.
| CJC-1295 / Ipamorelin | MK-677 | |
|---|---|---|
| What it is | The default growth hormone blend: a GHRH analogue with a ghrelin agonist, usually 5 mg of each. Two mechanisms that genuinely differ, unlike the triple. | An orally active ghrelin receptor agonist that raises growth hormone and IGF-1. Not a peptide, and not injected. It is a small molecule taken by mouth. |
| EvidenceHow much human evidence exists, not how well it works. | Preclinical | Early human trials |
| Regulatory statusReviewed 2026-08-25 | Not approved anywhere as a mixture or as either of its parts. Sold as a research chemical, in at least two vial sizes at the same ratio. | Not approved for human use in any jurisdiction. Development was not completed. It is widely sold as a 'research chemical' or mislabelled as a dietary supplement, which it is not. It is an unapproved drug. |

| Half-life | Not recorded | 24 hours |

| Storage once mixed | Refrigerated at 2–8 °C and used within about 30 days. A blend cannot be split. A contaminated vial takes every component with it. | Not applicable. Liquid preparations sold in solution should follow the seller's storage instructions, which is a weaker guarantee than it sounds. |

This page is educational. It describes what published research reports, not what you should do. Peptides discussed here are largely not approved for human use, and nothing on BioAlmanac is medical advice. Nothing here ranks these two against each other. A table can show that one has more human evidence behind it or costs less per milligram; neither of those is a recommendation, and the right comparison for any person is one their doctor makes with them.
