Recovery & tissue support
Peptides that support connective tissue, musculoskeletal wellness, and recovery after activity or strain.
Peptide therapy
Advanced health optimization through peptide therapy.
Peptides support recovery, metabolism, and tissue repair by targeting key biological signaling pathways. Browse our library, learn what each one supports, then shop products in our shop.

What are peptides?
Peptides are short chains of amino acids—the same building blocks that make up proteins, but typically 50 or fewer amino acids in length. Despite their simplicity, peptides play critical signaling roles in the body, regulating growth, metabolism, healing, and cognitive function.
Some peptides occur naturally in the body; others are made in a lab, often modeled on natural sequences. By binding to specific receptors on cells, peptides can trigger targeted biological responses that support recovery, healthy aging, and performance.
Intrinsic Longevity offers a full peptide library, with availability and pricing in our shop. Some therapies—such as NAD+—require an online visit with a licensed provider before access.
Classification
Types of peptides
Peptides are often described in two ways: where they come from, and the kind of role they play in the body. Those labels are educational—they help explain the science behind a compound.
On this site, the library is organized by benefit area (recovery, wellness, sleep, performance) so you can browse by goal. Origin and function labels may appear on individual compound pages; they are not how the catalog is filtered.
- By origin: some peptides occur naturally in the body (endogenous)—for example, collagen-related peptides. Others are made in a lab (synthetic), often modeled on natural sequences, for specific applications.
- By role: many act as messengers between cells (signaling); some support connective tissue (structural); and in wellness settings they are used toward targeted health goals. One peptide can fit more than one of these descriptions.

Who it's for
Who considers peptide therapy
People seeking peptide therapy often fall into a few groups: those focused on recovery and physical performance, those pursuing longevity and healthy aging, and those looking to support sleep, wellness, or general vitality.
Review each compound page and consult your healthcare provider if you have questions about fit—or book an online visit with one of our licensed providers to review options and ask questions. Suitability is determined by a licensed provider. This page describes categories generally and does not recommend a specific compound, dose, or protocol.
Categories at a glance
Peptide categories, in general terms
Broad benefit-area overviews. Tags on each compound card below use the same category names—they describe goals, not separate products.
Wellness & vitality
Compounds that support energy, healthy aging, immune signaling, and general vitality.
Sleep & restoration
Peptides that support sleep quality, daily restoration, and cognitive recovery.
Performance & body composition
Peptides that support training, metabolic wellness, and body-composition goals.
Category tags on compound cards below match these benefit-area groupings.
Peptides in our shop are sourced from US-licensed manufacturers.
Therapies that require medical evaluation are sourced from FDA-regulated 503A compounding pharmacies. For therapies that require medical evaluation, every protocol is designed by a licensed provider.

Peptides therapies, explained
What each therapy supports and how to access it.
BPC-157
Lab-made peptide
A lab-made peptide copied from a protein in stomach fluid, studied for its role in tissue repair, new blood vessels, and collagen.
Ipamorelin
Growth hormone releaser
A lab-made peptide that nudges the pituitary gland to release growth hormone in its normal on-and-off pattern.
NAD+
Coenzyme
A helper molecule found in every cell that cells use to turn food into energy and to run repair enzymes.
Glutathione
Antioxidant tripeptide
An antioxidant your body already makes that helps the liver clear waste and helps cells handle everyday chemical stress.
AOD-9604
Growth hormone fragment
A small piece of the growth hormone molecule, studied for the part of that hormone linked to breaking down stored fat.
CJC-1295 (without DAC)
Growth hormone releaser
A short-acting copy of the brain signal that tells the pituitary gland to release growth hormone in short bursts.
CJC-1295 (with DAC)
Growth hormone releaser
A longer-acting copy of the brain signal for growth hormone, changed so it sticks to a blood protein and stays active for days.
DSIP
Delta sleep-inducing peptide
A brain peptide named for its link to delta waves, the slow brain waves that show up during the deepest stage of sleep.
Epithalon
Four amino acids
A four-amino-acid peptide modeled on a substance from the pineal gland, studied for links to telomeres and the sleep-wake clock.
GHK-Cu
Copper-carrying tripeptide
A three-amino-acid peptide that carries a copper atom, best known in skin and wound-healing research for its link to collagen.
IGF-1 LR3
Modified growth factor
A changed version of a natural growth factor, built to stay active longer than the form the body makes on its own.
KPV
Alpha-MSH fragment
A three-amino-acid piece of a natural hormone, studied for calming immune signals in the gut lining and the skin.
Melanotan 2
Melanocortin compound
A lab-made copy of the hormone that tells skin to make pigment; it also touches appetite and arousal signals, and carries real safety concerns.
MOTS-C
Mitochondrial DNA
A rare peptide written in the DNA of mitochondria, the parts of the cell that make energy, and studied as a message from them to the rest of the cell.
Pinealon
Three amino acids
A very short peptide, three amino acids long, studied for signals that protect brain cells and steady the sleep-wake rhythm.
Selank
Based on tuftsin
A lab-made peptide based on a natural immune fragment, studied in Russia for calm focus without the drowsiness of a sedative.
Semax
ACTH fragment
A lab-made peptide built from a piece of a natural stress hormone, studied for focus, mood, and brain-protection signals.
SS-31
Elamipretide (Forzinity)
Elamipretide, a peptide that gathers at the inner wall of mitochondria and binds a fat called cardiolipin that the wall needs to work.
TB-500
Thymosin beta-4 fragment
A lab-made piece of thymosin beta-4, a natural protein that helps cells move toward damaged tissue and rebuild it.
Tesamorelin
Growth hormone releaser
A prescription copy of the brain signal for growth hormone, approved to reduce excess belly fat in adults living with HIV.
Thymosin Alpha-1

A clinic name for three recovery peptides used together: BPC-157, GHK-Cu, and TB-500.
KLOW
Named peptide blend
The three GLOW peptides plus KPV, which adds a gut-lining and immune-calming piece to the mix.
Wolverine
Named peptide pairing
A clinic name for the simplest recovery pairing: BPC-157 and TB-500, without the extra peptides in GLOW or KLOW.
