These peptides are studied for their potential roles in cellular repair, longevity, mitochondrial health, and anti-aging pathways.
Epithalon
May help extend the lifespan of cells by supporting healthy DNA and telomere function. It's being studied for its potential anti-aging and regenerative effects.
NAD+
A molecule found in all cells that helps turn food into energy. Levels drop as we age, and research looks at how restoring NAD+ could improve energy and slow aging.
GHK-Cu
A copper-based peptide that supports skin repair and collagen production. It also helps protect cells from damage caused by stress and aging.
SS-31
A peptide that targets mitochondria—the energy centers of your cells—to improve their function and reduce fatigue or cellular stress.
Thymosin Alpha 1 (TA1)
Supports the immune system and may help the body respond better to infections and stress as it ages.
MOTS-c
A peptide made in your mitochondria that helps regulate how your body uses energy. It’s being researched for metabolism and age-related disease support.
Glutathione
A powerful antioxidant your body naturally makes to fight toxins. It’s essential for healthy aging, immune support, and detoxification.
Curcumin
The active ingredient in turmeric, known for fighting inflammation and free radicals that cause aging and chronic disease.
Survodutide
A new peptide being studied for weight loss and liver health. It targets hormones that control hunger and fat metabolism.Cognitive Function
Peptides in this group are linked to neuroprotection, mood regulation, brain function, and nootropic support.
Semax
A brain-boosting peptide that may improve memory, learning, and focus. It's also studied for protection against brain damage or stress.
Selank
Often called an “anti-anxiety peptide,” it helps regulate mood, calm stress, and support clear thinking—without sedation.
BDNF
A protein your brain uses to grow and protect neurons. It’s crucial for learning, memory, and mental resilience.
PE-22-28 (Mini-Spadin)
A small peptide studied for rapid antidepressant effects. It may help improve mood by acting on brain pathways differently from traditional meds.
DSIP
Known as the "Delta Sleep-Inducing Peptide," it helps regulate deep, restful sleep and may also calm stress responses.
Oxytocin
Often called the "love hormone," it helps with emotional bonding, trust, and social connection—and plays a role in sexual health too.Fitness & Performance
These peptides are commonly researched in relation to muscle development, fat metabolism, stamina, and growth hormone stimulation.
IGF-1 LR3
A growth factor that helps build muscle and repair tissue. It lasts longer in the body than natural IGF-1, which may make it more effective in research settings.
IGF-1 DES
A fast-acting version of IGF-1 used in targeted muscle repair. It's being studied for rapid growth in specific areas.
CJC-1295 (No DAC)
Stimulates your body to release more of its own growth hormone, mimicking natural hormone cycles.
Ipamorelin
Encourages growth hormone release without affecting other hormones like cortisol. It’s often researched for performance and recovery.
Sermorelin
Works like your body’s natural GHRH (growth hormone releasing hormone) to trigger GH production. It’s a more natural, indirect way to support performance.
GHRP-2
A peptide that stimulates growth hormone release and may also increase appetite. It’s being studied for body composition support.
GHRP-6
Similar to GHRP-2 but also linked to fat loss and muscle recovery. Known to stimulate hunger, which may aid bulking in fitness studies.
Hexarelin
A potent GH-releasing peptide with possible benefits for muscle gain and heart health.
Tesamorelin
FDA-approved to reduce belly fat in HIV patients. Also being studied for general fat loss and hormone regulation.
AOD 9604
A modified part of growth hormone that focuses on fat burning without affecting blood sugar. Being studied for safe weight management.
SLU-PP-332
An exercise-mimicking compound being studied for boosting metabolism, energy, and fat burning without actual physical exertion.General Health
This category includes peptides investigated for metabolic health, immune modulation, gut and respiratory function, and overall systemic support.
Thymosin Alpha 1 (TA1)
Supports immune balance and is being looked at in infections, cancer, and autoimmunity. It may help your body respond better to immune stress.
KPV
A small peptide that helps reduce inflammation, especially in the gut and skin. Also shows potential for immune and recovery support.
LL-37
A natural antimicrobial peptide that helps the body fight infection, heal wounds, and manage inflammation.
LL-37 Complex
A blend of LL-37 with added ingredients for broader immune and tissue support—often used in research on wound healing and gut health.
Curcumin
The compound in turmeric with strong anti-inflammatory and antioxidant effects. Studied in everything from joint pain to brain health.
MOTS-c
Also found in the “Aging” section—it supports metabolism, insulin sensitivity, and physical endurance.
Glutathione
Vital for detox, immune defense, and antioxidant protection. It supports overall wellness and cellular function.
NAD+
Also listed under “Aging,” NAD+ is essential for energy production and DNA repair, helping cells stay resilient as we age.
Selank
While primarily known for mood support, it also shows immune-regulating properties in research.
Semax
Has anti-inflammatory and nerve-protective effects, in addition to its role in cognitive enhancement.Recovery
Peptides in this group support research in tissue repair, inflammation reduction, and regenerative processes.
BPC-157
One of the most studied healing peptides—known for its role in tendon, ligament, and gut repair. Helps accelerate recovery from injury.
TB-500
A synthetic version of thymosin beta-4, it supports tissue regeneration, cell movement, and healing of soft tissues.
GHK-Cu
Promotes wound healing, skin repair, and regeneration. Also reduces inflammation and oxidative stress.
KPV
Reduces inflammation and supports the healing of skin and gut tissue. Great potential for recovery-related research.
DSIP
Aids in sleep regulation, which is essential for physical recovery. Also helps regulate hormone release and stress response.
LL-37
Promotes healing and has antimicrobial properties, which support tissue regeneration and defense.
Follistatin 344
Blocks myostatin, a protein that limits muscle growth. Studied for its muscle-building and regenerative potential.Sexual Health
These peptides are explored for hormonal balance, libido enhancement, reproductive health, and sexual function.
PT-141 (Bremelanotide)
A peptide that boosts sexual desire by acting on the brain—not the blood vessels. Used for low libido in women and men.
Kisspeptin
A key regulator of fertility and reproductive hormones. It helps signal the brain to start the hormonal cascade for ovulation or sperm production.
HCG
Mimics the body’s luteinizing hormone to increase testosterone in men or trigger ovulation in women. Often used in fertility and hormone therapies.
