What Are Peptides?
Peptides are short chains of amino acids—typically between 2 and 50 amino acids linked together. They are the building blocks of proteins but are smaller in size, which allows them to be absorbed more easily by the body and to interact with specific cellular receptors.
In the context of performance and health optimization, therapeutic peptides are compounds that signal the body to perform specific functions—such as releasing growth hormone, accelerating tissue repair, modulating inflammation, or enhancing cognitive function. Unlike synthetic hormones, most peptides work by stimulating your body's own natural processes rather than replacing them.
Peptides are used across a wide spectrum of applications: from anti-aging and longevity protocols to injury recovery, muscle building, fat loss, and cognitive enhancement. Many are prescribed through telemedicine clinics, while others remain in research stages.
Why We List These Peptides
This guide is designed to educate—not prescribe. We provide evidence-based information on peptides that are commonly discussed in performance, longevity, and health optimization communities. Each entry includes the peptide's mechanism of action, potential benefits, dosing protocols from clinical literature, and known side effects. Our goal is to help you have informed conversations with your healthcare provider about whether peptide therapy might be appropriate for your goals.
Important: Peptides vary in their regulatory status—some are FDA-approved for specific conditions, some require a prescription, and others are available only as research compounds. Always consult with a licensed healthcare provider before using any peptide therapy. This information is for educational purposes only.

A selective growth hormone secretagogue that triggers GH release without affecting cortisol or prolactin levels, ideal for clean anti-aging protocols.
CJC-1295
Extended-Release GH Optimization
A long-acting GHRH analog often paired with Ipamorelin for synergistic GH release, promoting sustained muscle growth and fat metabolism.
PT-141
Restore Desire & Performance Naturally
A melanocortin receptor agonist that enhances libido and sexual function in both men and women through central nervous system activation.
GHK-Cu
The Copper Peptide for Regeneration & Longevity
A naturally occurring copper peptide with powerful skin rejuvenation, wound healing, and anti-inflammatory properties that decline with age.
Epithalon
The Telomere-Extending Longevity Peptide
A tetrapeptide that activates telomerase, potentially extending cellular lifespan and slowing biological aging at the DNA level.
MOTS-C
The Mitochondrial Exercise Mimetic
A mitochondrial-derived peptide that activates AMPK and mimics many benefits of exercise, enhancing metabolic health and longevity.
FOXO4-DRI
The Senolytic Cell Clearing Peptide
A groundbreaking senolytic peptide that selectively eliminates senescent 'zombie' cells, potentially reversing aspects of aging.
NAD+
The Cellular Energy Currency
The essential coenzyme for cellular energy production that declines with age, supporting mitochondrial function, DNA repair, and longevity pathways.
Selank
The Anxiety-Reducing Nootropic
A Russian-developed anxiolytic peptide that reduces anxiety and enhances cognitive function without sedation or addiction potential.
Semax
The Cognitive Performance Enhancer
A powerful nootropic peptide that enhances memory, focus, and neuroprotection through BDNF stimulation and dopamine modulation.
DSIP
The Deep Sleep Peptide
Delta Sleep Inducing Peptide that promotes natural, restorative deep sleep and helps normalize disrupted sleep patterns.
AOD-9604
The Fat-Burning GH Fragment
A modified fragment of growth hormone (176-191) that promotes fat loss without the negative effects of full GH, including no impact on blood sugar.
Hexarelin
The Powerful GH Secretagogue
One of the strongest growth hormone releasing peptides, providing robust GH pulses for muscle growth, recovery, and cardiac protection.
GHRP-2
The Balanced GH Releaser
A growth hormone releasing peptide offering potent GH release with moderate effects on appetite and cortisol, popular for body composition.
GHRP-6
The Appetite-Boosting GH Releaser
A potent growth hormone secretagogue that dramatically increases appetite and GH release, ideal for those seeking mass gains.
Thymosin Alpha-1
The Master Immune Regulator
A naturally occurring thymic peptide that enhances immune function, used clinically for infections, cancer support, and immunodeficiency.
LL-37
The Human Antimicrobial Peptide
A naturally occurring human antimicrobial peptide with broad-spectrum activity against bacteria, viruses, and fungi, plus wound healing properties.
Follistatin-344
The Myostatin Inhibitor for Muscle Growth
A powerful protein that inhibits myostatin, the body's natural limiter of muscle growth, enabling enhanced muscle development.
Melanotan II
The Tanning & Libido Peptide
A melanocortin peptide that promotes skin tanning without UV exposure while also enhancing libido and reducing appetite.
Kisspeptin-10
The Master Hormone Regulator
A peptide that sits atop the reproductive hormone cascade, stimulating natural GnRH and potentially restoring healthy hormone function.
