Most Popular Peptide Solutions

Melanotan 2 – 10mg

$ 50.00
Melanotan-2 (MT-2) is a synthetic analogue of alpha-melanocyte-stimulating hormone. Developed in the 1980s, Melanotan-2 has been shown to increase sexual arousal, reduce compulsive/addictive behavior, curb hunger and increase melanin production. Research has shown the peptide to stimulate melanocytes therefore producing increased skin pigmentation and may help to combat autism when used during early childhood development.

Melanotan 1 (MT1) 10mg

$ 50.00
Melanotan 1 is similar to naturally occurring alpha melanocyte stimulating hormone alpha-MSH (Melanotan 2). Alpha-MSH is known for its influence on melanocytes, the cells in skin and hair responsible for pigmentation. This function is mediated via strong binding to melanocortin receptor 1. Alpha-MSH is a non-selective full agonist of melanocortin receptors 1, 3, 4, and 5. Melanotan 1 differs from alpha-MSH (Melanotan 2) by a single amino acid and was actually first developed as a sunless tanning agent. Research into melanocortin receptors and their effects, scientists quickly discovered that while melanotan 1 did indeed cause pigmentation, and altered baseline metabolism. Subsequent study of melanotan 1 and other melanocortin-binding proteins helped scientists to better understand the melanocortin signaling system.

ARA290 – 10mg

$ 95.00
ARA-290 is variant of erythropoietin which has been shown to decrease inflammatory pathways through paracrine signalling and the innate repair receptors. Research has shown ARA-290 to help reduce HbA1c, improve cholesterol, modulate neuropathic pain and stimulate wound repair.

KPV – 5mg & 10mg

Price range: $ 65.00 through $ 110.00
Select options This product has multiple variants. The options may be chosen on the product page
KPV is a potent anti-inflammatory peptide that has shown promise in a number of disease conditions. The most active research is in the treatment of inflammatory bowel disease where the peptide has showed substantial promise. Research in wound healing also reveals that KPV and other alpha-MSH derivatives may offer a host of benefits that speed wound healing, reduce infection, fight inflammation, and lead to better cosmetic results. KPV and similar peptides could become mainstays not just in wound healing, but in scar reduction following surgery.

MOTS-C – 5mg & 10mg

Price range: $ 65.00 through $ 110.00
Select options This product has multiple variants. The options may be chosen on the product page
MOTS-c is a mitochondrial-derived peptide (MDP) composed of 16 amino acids, which plays a critical role in cellular metabolic regulation. Synthesized within mitochondria, MOTS-c functions by modulating the cellular energy balance through pathways involved in glucose metabolism, insulin sensitivity, and cellular stress response.  MOTS-c exerts its effects by translocating to the nucleus, where it influences the expression of genes related to mitochondrial biogenesis and metabolic regulation, particularly under conditions of metabolic stress. Research has shown this peptide to improve exercise capacity, reduce obesity, insulin resistance and other disease processes such as osteoporosis and the mitigation of metabolic disorders and age-associated diseases. The Mitochondrial-Derived Peptide MOTS-c promotes metabolic homeostasis and longevity, improves exercise capacity, reduces obesity, insulin resistance and other disease processes such as osteoporosis.

DSIP – 5mg & 10mg

Price range: $ 50.00 through $ 195.00
Select options This product has multiple variants. The options may be chosen on the product page
Delta-sleep-inducing peptide is a neuropeptide that affects a number of endocrine and physiological processes within the central nervous system. DSIP is of primary interest for its abilities to reduce oxidative stress, normalize myocardial contractility. It is also being studied as a potential target in the treatment of major depressive disorder.

FOXO4-DRI – 10mg & 20mg

Price range: $ 300.00 through $ 550.00
Select options This product has multiple variants. The options may be chosen on the product page
FOX04-DRI (Retro-Inverso) is a synthetic, slightly modified version of the standard FOXO4 protein. The modification prolongs half-life of the protein and allows it to interfere with normal FOXO4 function. FOXO4-DRI has been shown in research to prevent normal FOXO4 binding to p53, thereby allowing for elimination of senescent cells, improved organ function, and younger tissue “biological age.” FOXO4-DRI impacts insulin signaling, cell cycle regulation, and oxidative stress signaling pathways. FOXO4-DRI is a cell penetrating peptide shown to selectively induce apoptosis of senescent cells thereby reversing effects of aging in animal studies.

Humanin – 5mg & 10mg

Price range: $ 95.00 through $ 155.00
Select options This product has multiple variants. The options may be chosen on the product page
Humanin is a naturally occurring micro-peptide found in mitochondria. It protects cells from apoptosis and may be useful in staving off heart, eye, brain, and muscle diseases. Humanin is one of a select, small class of compounds targeting mitochondrial function and thus improving cellular energy efficiency and homeostasis.

Selank – 5mg & 10mg

Price range: $ 55.00 through $ 100.00
Select options This product has multiple variants. The options may be chosen on the product page
Selank peptide is a short, synthetic analogue of tuftsin. It has profound anti-anxiety properties. Selank also boosts memory and learning and has been shown to have beneficial effects on pain perception. Selank is a short, synthetic analogue of tuftsin. It has profound anti-anxiety properties.

Select options This product has multiple variants. The options may be chosen on the product page
N-Acetyl Selank Amidate improves on every aspect of Selank by increasing its potency, half-life, absorbability, and the ease with which it crosses the blood-brain barrier. These features help it to enhance the effects of Selank, which has been found in animal studies to protect the central nervous system from disease and trauma, reduce anxiety, improve learning, improve memory. N-Acetyl Selank Amidate is best thought of as an enhanced version of Selank. Research has shown that N-Acetyl Selank Amidate improves on every aspect of Selank by increasing its potency, half-life, absorbability, and the ease with which it crosses the blood-brain barrier. These features help to enhance the effects of Selank, which has been found in animal studies to protect the central nervous system from disease and trauma, reduce anxiety, improve learning, improve memory, and alter the process of blood clotting. While more research remains to be done, Selank and other glyprolines offer an insight into how DNA expression patterns can be altered by a single peptide to produce dramatic effects.
