AHK-Cu (Copper Peptide)

Synthetic copper-binding tripeptide targeting dermal papilla cells and hair follicles. Stimulates hair follicle elongation, promotes cell proliferation, increases VEGF production, and inhibits TGF-β1. Supports skin regeneration through fibroblast activation and collagen synthesis.

COA Verified

Purity: ≥98% (HPLC verified)

Botulinum Toxin

A bacterial neurotoxin protein that blocks acetylcholine release at cholinergic nerve terminals and is used clinically for multiple neurologic, muscular and aesthetic indications.

COA Verified

Purity: ≥98% (HPLC verified)

GHK (Glycyl-L-Histidyl-L-Lysine)

Naturally occurring copper tripeptide found in human plasma, saliva, and urine. GHK-Cu affects 31.2% of human genes and declines significantly with age—from ~200 ng/ml at age 20 to ~80 ng/ml at age 60. Known for exceptional skin regeneration, wound healing, and anti-aging properties.

COA Verified

Purity: ≥98% (HPLC verified)

GHK-Cu (Copper Peptide)

COA Verified

Purity: ≥98% (HPLC verified)

Hyaluronic Acid

A naturally occurring glycosaminoglycan and extracellular-matrix polymer that plays major roles in tissue hydration, viscoelasticity, cell signaling and structural support.

COA Verified

Purity: ≥98% (HPLC verified)

Matrixyl (Palmitoyl Pentapeptide-4)

A palmitoylated pentapeptide derived from the KTTKS sequence associated with procollagen signaling and widely studied as a cosmetic anti-aging ingredient.

COA Verified

Purity: ≥98% (HPLC verified)

Melanotan I (MT-1)

Synthetic analog of α-MSH that selectively targets MC1 receptors for melanin stimulation. FDA-approved as SCENESSE implant for erythropoietic protoporphyria (EPP). Research-grade injectable form enables flexible dosing versus the implant version.

COA Verified

Purity: ≥98% (HPLC verified)

Melanotan II (MT-2)

Melanotan II is a synthetic analog of alpha-melanocyte-stimulating hormone (α-MSH) that activates melanocortin receptors throughout the body. MC1R activation triggers melanin production for tanning, while MC4R affects sexual arousal and appetite control.

COA Verified

Purity: ≥98% (HPLC verified)

PTD-DBM

A cell-penetrating peptide designed to interfere with CXXC5-Dvl signaling and activate Wnt/β-catenin signaling, investigated primarily in hair-growth and tissue-regeneration models.

COA Verified

Purity: ≥98% (HPLC verified)

SNAP-8 (Acetyl Octapeptide-3)

Synthetic octapeptide functioning as topical Botox alternative, targeting dynamic facial wrinkles through SNARE complex modulation. Up to 63% wrinkle depth reduction demonstrated clinically.

COA Verified

Purity: ≥98% (HPLC verified)
