Peptides 101: what they are, what they're not

A grounded primer on peptide therapy — what's well-studied, what's promising, and what's hype.

What peptides actually are

Peptides are short chains of amino acids — smaller than proteins, large enough to act as signaling molecules. Your body makes thousands. Insulin is a peptide. So is oxytocin.

In therapeutic medicine, we use peptides to *signal* tissues to do specific things: repair, regenerate, sleep, build, recover.

What's well-supported

  • Peptides are an area of active research. Availability for prescribing or compounding depends on current federal and state requirements and pharmacy sourcing.
  • Sermorelin, CJC-1295/Ipamorelin — growth hormone optimization (more physiologic than synthetic GH)
  • Tesamorelin — visceral fat reduction
  • Luma does not offer peptides that are not currently legally available, and no outcome is promised.
  • DSIP, Selank — sleep and stress

What's promising but newer

  • MOTS-c — mitochondrial function
  • Epitalon — longevity and pineal regulation
  • Thymosin Alpha-1 — immune modulation

What's hype

Be cautious of any product or claim promising a specific outcome. Peptides are not a substitute for evaluation by a licensed healthcare provider, and results are never guaranteed.

How we prescribe

Sourced from licensed US compounding pharmacies, dosed by your provider, monitored over time. We don't recommend research-grade peptides from internet vendors. Quality, dosing, and supervision matter.
