Tier C · Early / limited human evidence
CJC-1295
Human studies confirm powerful GH-axis effects; therapeutic benefits are still not established.
Why researchers care
Potential human relevance
- Sustained dose-dependent increases in growth hormone and IGF-1 in healthy adults
- Preserved pulsatile GH secretion in human research
- Longer pharmacologic action than native GHRH
What the human evidence says
Evidence, not extrapolation
Small controlled human studies demonstrated prolonged GH and IGF-1 elevation. Those studies establish endocrine activity—not proven benefits for fat loss, anti-aging, muscle gain or injury recovery.
How to think about it
The Yooper Peptides take
CJC-1295 is a good example of why biomarker movement and clinical benefit should be kept separate.
