Sample Descriptions

Argireline : Also known as Acetyl-Hexapeptide-3 and Hexapeptide-8. Argireline acetate temporarily limits the overproduction and release of neurotransmitters that initiate and control the intensity of facial muscle contractions. At a 10% concentration, Acetyl Hexapeptide 3 has been shown to reduce the depth of wrinkles up to 30% after 30 days of trial use. Argireline is a peptide (acetyl hexapeptide-3) that inhibits SNARE complex formation and catecholamine release, resulting in the reduction of the degree of existing facial wrinkles. Argireline sequence is Ac-Glu-Glu-Met-Gln-Arg-Arg-OH.Acetate.

Cosmetic peptides

Palmitoyl-TetraPeptide-7 : powerful anti-aging, wrinkle smoothing, cutaneous barrier repair. Pal-GQPR-OH.

Hexapeptide-2 : Skin brightening/whitening and age spot repair.

Melanostatine-5 : Melanocyte inhibiting factor (MSH release inhibitor) used for skin brightening and age spot corrections.

Palmitoyl-Hexapeptide: anti-aging, matrikine peptide which helps repair damage to the cutaeous matrix. Stimulates human fibroblasts. Pal-Val-Gly-Val-Ala-Pro-Gly.


GHK-Cu : Copper-Tripeptide. CAS# 89030-95-5. Available in gram (g) to multi-kg (kg) quantities.  In-stock in bulk kg quantities, for quick shipment.  We can handle your research to full commercialization needs.  Contact us today for pricing.

Proven anti-aging and wrinkle smoothing peptide. GHK-Cu increases the thickness of the epidermis and dermis, increases skin elasticity, and reduces wrinkles, resulting in a removal of skin imperfections such as blotchiness and sun damage marks, while producing a significant increase in subcutaneous fat cells. Also used for hair growth applications.

Cosmetic peptides

AHK-Cu : Copper-Tripeptide Complex. Powerful Hair Growth peptide. Increases growth factors such as VEGF and FGF, and to promote follicle strength and thickness.

Cosmetic peptides

Acetyl-Decapeptide-3 : anti-aging/skincare peptide, also known as Rejuline.

Acetyl-Hexapeptide-3 : Ac-Glu-Glu-Met-Gln-Arg-Arg-CONH2 (Ac-EEMQRR-CONH2). Used for Anti-aging, wrinkle reduction formulations.

Octapeptide-2 : powerful growth stimulant for hair growth



rh-Oligopeptide-1 (Human EGF): Highly active anti-aging/skincare peptide. Stimulates the growth and proliferation of skin, cornea and racheal epithelium tissue in vivo. Accelerates the healing process of epidermis damage on skin, cornea, etc. Represses the gastric acid excretion, and accelerates the proliferation of epithelial cells in human and animals. See our detailed Technical Data Sheet.

Palmitoyl-KTTK : also effective in boosting collagen production, firming and toning skin. (Pal-KTTK)
stimulate the feedback loop triggering the synthesis of new collagen as well as other components of the skin matrix.

Palmitoyl-RFK (Palmitoyl-Tripeptide): The anti-aging benefits of Palmitoyl Tripeptide include stimulation of collagen synthesis, actively removes any type of wrinkle, skin firming and moisturizing properties. Palmitoyl Tripeptide has been clinically proven to be safe and effective. Suggested concentrations are 1-3%. (Pal-RFK-OH)

Palmitoyl-GHK  (Palmitoyl-Oligopeptide) : Now called Palmitoyl-Tripeptide-1, it stimulates the feedback loop triggering the synthesis of new collagen as well as other components of the skin matrix. (Pal-GHK-OH) (Palmitoyl-Oligopeptide).

Acetyl-Octapetpide-8 (SNAP-8): Elongated version of the Acetyl-Hexapeptide. SNAP-8 reduces the depth of wrinkles on the face caused by the contraction of muscles of facial expression, especially in the forehead and around the eyes. SNAP-8 is a safer, cheaper, and milder alternative to Botulinum Toxin, topically targeting the same wrinkle-formation mechanism in a very different way. SNAP-8 can be incorporated in cosmetic formulations such as emulsions, gels, sera, etc., where removal of the deep lines or wrinkles in the forehead or around the eyes area is desired. Ac-Glu-Glu-Met-Gln-Arg-Arg-Ala-Asp-NH2.

Biotinoyl-GHK (Biotinoyl-Tripeptide-1): Anti-Aging, Hair growth, Skincare applications.
Also known as: Biotin-GHK-OH, Biotinyl-Tripeptide, and Biotinyl-Tripeptide-1

    • Reduces hair loss:. Anchors the hair for better “rooting” of the hair to the skin.
    • Stimulates hair growth – Biotin proven to increase the Anagen phase.

    • Binds effectively to the collagen matrix and red blood cell (RBC) membrane.
    • Increases the NATURAL copper concentration by ninefold at the wound site, making it an alternative to GHK-Cu.
    • Simply put, RS-Biotinoyl-Tripeptide-1 is the most cost effective, multi-use bioactive peptide available today. RS Synthesis manufactures all peptides in-house under strict quality guidelines, and can provide Biotin-GHK in the standard solution or pure lyophilized powder form at custom purity levels.

      Also known as: Palmitoyl-Tripeptide-5

        • Significantly stimulates human skin collagen production in fibroblasts
        • Slows the degradation of collagen over time
        • Palmitic acid on the N-terminus increases penetration through the epidermis
        • Short chain sequence remains stable after epidermal penetration

      Highly concentrated peptide/solution for anti-aging formulations. RS Synthesis manufactures all peptides in-house under strict quality guidelines, and can provide Palmitoyl-Tripeptide-5 in the standard solution or pure lyophilized powder form at custom purity levels.
