The original GHRH analog, FDA-approved for childhood GH deficiency. Considered the safest and most well-studied GH secretagogue with the longest track record in clinical use.

One of the cleanest GH-releasing peptides available, known for its selective action and minimal side effects. Often considered the best starter peptide for GH optimization.

The only orally active GH secretagogue — technically not a peptide but a small molecule. Produces sustained GH elevation and is the most studied ghrelin mimetic for anti-aging applications.

The shorter-acting version of CJC-1295, often called Mod GRF 1-29. Provides a natural GH pulse pattern rather than sustained elevation, making it more physiological.

The flagship longevity peptide, developed by Russian scientist Vladimir Khavinson over 35 years of research. Studied for telomere elongation, circadian rhythm regulation, and lifespan extension.

A naturally occurring neuropeptide that specifically promotes deep delta-wave sleep. Studied for insomnia, stress resilience, pain management, and withdrawal support.
