mel-ah-TOE-nin
The hormone your brain makes when it gets dark — supplementing it helps reset your sleep-wake cycle.
leer-ah-GLOO-tide
An earlier GLP-1 weight loss injection — taken daily instead of weekly, with a strong safety track record.
Prescribed by licensed providers through compounding pharmacies. Published clinical evidence supports use.
ser-more-ELL-in
A peptide that tells your pituitary gland to make more growth hormone naturally — supports sleep, recovery, and body composition.
N-A-D plus
A coenzyme in every cell that powers your mitochondria — levels drop with age, and restoring them supports energy and cellular repair.
G-H-K copper
A naturally occurring copper peptide that stimulates collagen, promotes skin repair, and supports hair growth.
METH-ih-leen blue
One of the oldest synthetic compounds in medicine — boosts mitochondrial energy production and supports cognitive clarity.
rap-ah-MY-sin
The most studied longevity compound — activates cellular cleanup by telling your cells to switch from 'growth mode' to 'maintenance mode.'
gon-ad-oh-RELL-in
A natural hormone analog that tells your body to produce its own testosterone — preserves fertility unlike direct TRT.
B-P-C one-fifty-seven
A peptide derived from a stomach protein that accelerates healing of tendons, muscles, gut lining, and other tissues.
P-T one-forty-one / brem-el-AN-oh-tide
A peptide that increases sexual desire by acting on the brain — works differently from ED medications that only improve blood flow.
C-J-C twelve-ninety-five
A long-acting growth hormone releaser that provides sustained GH stimulation over days rather than minutes.
ip-ah-MORE-eh-lin
A selective growth hormone releaser that works through the 'hunger hormone' pathway — clean GH stimulation with fewer side effects.
C-J-C / ip-ah-MORE-eh-lin
The most popular growth hormone peptide combination — hits two pathways simultaneously for amplified GH release.
THY-moh-sin alpha one
An immune-modulating peptide that fine-tunes your immune system — helps it fight infections and cancer without overreacting.
dy-HEX-ah
A potent cognitive peptide that promotes new brain connections — millions of times more potent than BDNF at stimulating neural growth.
KISS-pep-tin
The 'master switch' hormone that controls your entire reproductive hormone cascade — being studied for fertility and desire.
tess-ah-MORE-eh-lin
An FDA-approved growth hormone releasing peptide that specifically reduces visceral (belly) fat.
ox-ee-TOE-sin
The 'bonding' hormone — supports emotional connection, reduces stress, and is being explored for mood and social function.
D-H-E-A
A precursor hormone that your adrenal glands make — your body converts it into testosterone and estrogen as needed.
preg-NEN-oh-lone
The very first hormone in the cascade — your body makes all other steroid hormones from this one starting material.
nal-TREX-own
A tiny dose of an opioid-blocker that paradoxically boosts your body's own endorphins and calms inflammation.
PEN-toe-san poly-SUL-fate
A semi-synthetic compound being explored for longevity — may support joint health and reduce cellular senescence.
five amino one M-Q
A small molecule that blocks an enzyme responsible for fat storage — may support weight loss by shifting metabolism toward fat burning.
ret-ah-TROO-tide
A triple-action weight loss molecule targeting three gut hormone receptors at once — the next evolution beyond tirzepatide.
MOTTS-see
A peptide encoded by your mitochondrial DNA that acts as an exercise mimetic — activating the same pathways as a workout.
S-S thirty-one / el-AM-ih-PREH-tide
A mitochondria-targeted peptide that concentrates inside your cells' power plants to restore their function.
ser-EE-bro-LY-sin
A brain-derived peptide mixture used globally for cognitive recovery — contains neurotrophic factors that support brain repair.
Early research stage. Not widely prescribed. Included for educational purposes only.
A modified fragment of growth hormone that targets fat burning without the growth-promoting side effects of full GH.
A tissue repair peptide found throughout your body — promotes healing of muscle, tendon, and connective tissue injuries.
A synthetic version of a pineal gland peptide that may activate telomerase — the enzyme that maintains chromosome caps associated with aging.
A Russian-developed synthetic peptide that reduces anxiety and supports immune function — based on the body's natural tuftsin molecule.
A synthetic brain peptide derived from ACTH that enhances focus, memory, and neuroprotection — developed in Russia.
A naturally occurring brain peptide that promotes deep delta-wave sleep — the most restorative phase of the sleep cycle.
An oral growth hormone secretagogue that stimulates GH release through the ghrelin receptor — taken as a pill, not an injection.
One of the earliest GH-releasing peptides — effective but causes strong hunger due to ghrelin receptor activation.
The most potent GH-releasing peptide — also has unique heart-protective properties, but causes desensitization with chronic use.
A protein that blocks myostatin — the molecule that limits muscle growth — potentially allowing greater muscle development.
Your body's natural antimicrobial peptide — part of your innate immune defense against bacteria, viruses, and fungi.
A research peptide targeting a specific potassium channel involved in depression — rapid-acting antidepressant potential.
A fragment of thymosin beta-4 being researched for inflammatory bowel conditions and wound healing.
A topical peptide that reduces expression lines by relaxing the muscle-nerve connection — a 'Botox in a bottle' approach.
A newer copper peptide being researched for hair growth — may stimulate follicles through a different pathway than GHK-Cu.
A mitochondrial-encoded peptide that protects cells from stress and death — one of the most exciting longevity research molecules.
A senolytic peptide that selectively destroys 'zombie' cells (senescent cells) that accumulate with age and drive inflammation.
A century-old antiparasitic drug being re-explored for its ability to modulate purinergic signaling — a pathway linked to autism and immune function.
