Peptides

SS-31

SS-31 is a groundbreaking, cell-permeable tetrapeptide that selectively targets and localizes to the inner mitochondrial membrane. It binds to cardiolipin, a phospholipid essential for mitochondrial structure and function. By stabilizing this membrane, SS-31 research focuses on improving mitochondrial efficiency, reducing electron leak and production of harmful free radicals, and enhancing cellular energy (ATP) production. It is a leading compound in research on mitochondrial health, which underpins the vitality of energy-intensive organs like the heart, brain, and muscles.

Peptides

TB-500

TB-500 is the synthetic version of the naturally occurring protein Thymosin Beta-4, which is present in high concentrations in wound tissue and blood cells. Its primary research focus is on its extraordinary capacity to promote healing and regeneration. It supports cell migration (essential for repair), angiogenesis (new blood vessel formation), and the upregulation of actin protein needed for cell structure and movement. This makes it a premier research peptide for studying recovery from musculoskeletal injuries, wound healing, and reducing excessive inflammation.

Peptides

Tesamorelin

Tesamorelin is a synthetic analogue of Growth Hormone-Releasing Hormone (GHRH) with specific, approved research applications. It stimulates the pituitary gland to produce and release its own growth hormone. Its well-documented effects include supporting a reduction in visceral adipose tissue (belly fat) while promoting lean body mass, making it a key compound for research into body composition and metabolic health, particularly in specific study populations.

Peptides

Thymosin Alpha-1

Thymosin Alpha-1 is a naturally occurring thymic peptide that plays a master regulatory role in the immune system. It is researched for its ability to modulate and enhance both innate and adaptive immune responses. Studies focus on its potential to promote T-cell differentiation and function, increase antibody response, and regulate cytokine production. This positions it as a vital compound for research into immune support, response to challenges, and overall immune system homeostasis.

Peptides

Cagrilintide & Cagrilintide+Semaglutide

It is a long-acting amylin analog that reduces appetite. The combination Cagrilintide 5mg + Semaglutide 5mg represents a next-generation, research-stage approach to metabolic health, uniting amylin and GLP-1 agonist pathways to potentially enhance weight loss and glucose control beyond single-agent effects.

Peptides

KPVKPV Selank

OxytocinOxytocin is a nine-amino-acid peptide hormone and neuromodulator. Peripherally, it stimulates uterine contractions during labor and milk ejection during breastfeeding. Centrally, it influences social bonding, trust, pair bonding, maternal attachment, and anxiety regulation, earning it the nickname "love hormone."

Peptides

Snap-8

Snap-8 is a peptide, a shorter version of Snap-25, used in research. It is studied for its potential to inhibit SNARE complex formation, which may modulate neurotransmitter release. Often explored in cosmetic applications, it is investigated for its ability to relax facial muscles, similar to a topical alternative to neuromodulators.

Peptides

B7-33

B7-33 is a synthetic, 27-amino-acid fragment derived from the human relaxin-2 hormone. It selectively activates the RXFP1 receptor, mimicking relaxin’s anti-fibrotic, vasodilatory, and anti-inflammatory effects without off-target hormonal activity. This makes it a promising therapeutic candidate for fibrosis, heart failure, and wound healing.

Peptides

Cardiogen

Cardiogen is a peptide that directs stem cells to become cardiomyocytes, aiding heart repair after damage. It activates key cardiac genes like GATA4, promoting tissue regeneration without major side effects. Used experimentally post-heart attack, it aims to reduce scarring and improve pumping function, offering a promising alternative to cell therapy.

Peptides

HCG

HCG (Human Chorionic Gonadotropin) is a peptide hormone that mimics luteinizing hormone (LH), stimulating testosterone production and testicular function. It's commonly used in medical settings to treat hypogonadism and fertility issues, and in fitness to prevent testicular shrinkage during steroid cycles.

Peptides

HGH

HGH (Human Growth Hormone) is a peptide hormone produced by the pituitary gland that stimulates growth, cell repair, and metabolism. It is used medically for growth deficiencies and muscle-wasting diseases. In fitness and anti-aging contexts, it is often misused to increase lean muscle mass, reduce body fat, and improve recovery, though side effects can include joint pain and insulin resistance.
