GHK-Cu (Copper Tripeptide-1, CAS 89030-95-5) is a naturally occurring copper‑binding tripeptide (glycine‑histidine‑lysine + Cu²⁺) supplied exclusively for laboratory research. It is used as a reference tool in studies of extracellular‑matrix remodeling, fibroblast activity, collagen/elastin gene expression, angiogenesis, and hair‑follicle biology. Each lyophilized vial is independently tested to ≥99% purity by HPLC, identity‑confirmed by mass spectrometry, and comes with a publicly verifiable third‑party Janoshik Certificate of Analysis. Store at −20°C; reconstitute with sterile diluent for use. Not for human or veterinary use.

Research-grade Methylcobalamin is the active, methylated coenzyme form of vitamin B12, supplied for laboratory study of one‑carbon metabolism, methylation pathways, homocysteine research, and neuronal research models. Each vial is lyophilized, ≥99% HPLC pure, MS‑confirmed, and backed by a publicly verifiable third‑party Janoshik COA. For research use only — not for human or veterinary use.

L-Glutathione (reduced form, GSH) is a tripeptide (γ-Glu-Cys-Gly) endogenously synthesized and the primary intracellular low-molecular-weight thiol. It functions as a co-substrate for glutathione peroxidases (GPx) and glutathione S-transferases (GST), and serves as a direct scavenger of reactive oxygen species. This research-grade preparation is supplied as lyophilized powder with ≥99% purity (HPLC), identity confirmed by MS, and accompanied by batch-specific Janoshik analytical certificate. Suitable for quantitative redox assays, enzyme kinetic studies, and drug-induced cytotoxicity models. Available in 600 mg and 1500 mg vial sizes. Not for human or veterinary use.

AHK-Cu (Copper Tripeptide-3) is a synthetic copper-binding tripeptide (Ala-His-Lys + Cu²⁺) supplied for laboratory study of hair-follicle biology, dermal-papilla cell proliferation, and VEGF signalling. A close analogue of GHK-Cu (differing by a single N-terminal methyl group), it is provided as a lyophilized powder with ≥99% HPLC purity, MS confirmation, and a third-party Janoshik COA. For research use only — not for human or veterinary applications.

LL-37 (Cathelicidin) – The only known human cathelicidin antimicrobial peptide. A 37‑aa cationic α‑helical peptide (MW ~4493.4 Da) for research in antimicrobial activity, innate immunity, immunomodulation, and wound‑healing models. ≥99% HPLC purity, MS‑confirmed, with third‑party Janoshik COA per batch. Lyophilized, store at −20°C. For research use only — not for human or veterinary use.

Melanotan Ⅰ (Afamelanotide) is a linear 13-amino-acid α-MSH analog and MC1R agonist intended for melanogenesis, melanocortin-receptor signaling, and melanocyte-biology research. It is supplied as a lyophilized powder with ≥99% HPLC purity, mass-spectrometry-confirmed identity, and a verifiable third-party Janoshik COA. For laboratory research use only. Not for human or veterinary use.

Melanotan Ⅱ (MT-II) is a cyclic 7-amino-acid α-MSH analog and non-selective melanocortin receptor agonist with activity at MC1R, MC3R, MC4R, and MC5R. It is intended for laboratory research involving melanocortin-receptor pharmacology, melanogenesis, receptor signaling, and structure–activity relationships. The product is supplied as a lyophilized powder with ≥99% HPLC purity, mass-spectrometry-confirmed identity, and a batch-specific third-party Janoshik COA. For research use only. Not for human or veterinary use.

SNAP-8 (Acetyl Octapeptide-3) is a synthetic octapeptide used in laboratory research involving SNARE-complex and SNAP-25 modulation, vesicle-fusion pathways, and cosmeceutical skin-science models. It is an extended analogue of Acetyl Hexapeptide-8 and is supplied as a lyophilized powder with ≥99% HPLC purity, mass-spectrometry-confirmed identity, and a batch-specific third-party COA. For research use only. Not for human or veterinary use.
