CJC-1295 vs Follistatin-344
Both are discussed for muscle & performance. 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 | Follistatin-344 | |
|---|---|---|
| What it is | A GHRH analogue that raises growth hormone by amplifying the body's own release signal. Sold in two forms whose durations differ by two orders of magnitude. | A myostatin-blocking protein with dramatic animal results, no human trials, and a serious question over whether what is sold is the real thing. |
| EvidenceHow much human evidence exists, not how well it works. | Early human trials | Preclinical |
| Regulatory statusReviewed 2026-08-12 | Not approved for human use in the United States. The FDA has identified CJC-1295 as a substance raising concerns for use in compounded preparations. Sold only as a research chemical. | Not approved anywhere, and never studied in a human trial as an injectable protein. Follistatin gene therapy has been studied in small trials for muscular dystrophy. The most advanced pharmaceutical work on the myostatin pathway — using a different molecule — was halted for safety. |

| Storage once mixed | Refrigerated at 2–8 °C. Do not freeze once mixed. | Refrigerated at 2–8 °C, and used quickly. A large glycoprotein is far less stable in solution than a short peptide, and it will not look any different once it has lost activity. |

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.
