What Are Peptides and How Do They Work?

The Body’s Built-In Messaging System

Peptides are short chains of amino acids—the same molecules that make up proteins—but they don’t build structure; they send instructions. Every system in the body runs on peptide signaling: telling cells when to heal, regenerate, or release hormones. As we age, those signals fade. Therapeutic peptides simply re-introduce or amplify the body’s own language of repair.

Types of Peptides and Their Roles

Different peptides target specific receptors:

CJC-1295 / Ipamorelin: stimulate growth-hormone release to support muscle, sleep, and recovery.
BPC-157 / TB-500: accelerate tissue and gut healing.
GHK-Cu: triggers collagen and elastin production for skin and hair health.
Sermorelin: gently restores GH rhythm in mid-life adults.
NAD⁺ precursors: revive mitochondrial energy.

Because they’re bioidentical, peptides integrate seamlessly with your body’s feedback loops—no synthetic hormone replacement required.

Why They Matter for Longevity

By re-activating youthful signaling, peptides can:

Increase lean mass and strength
Improve deep-sleep cycles
Enhance skin firmness and elasticity
Reduce inflammation and oxidative stress
Support cognitive function and mood

In short, they help you recover, rebuild, and stay sharper without overstimulating your system.

Safety and Personalization

Peptide therapy should always be prescribed and monitored. Dosing depends on goals, age, and baseline labs. Side effects are minimal—most peptides have decades of clinical safety data—but sourcing from sterile, verified pharmacies is essential.
