Selank
Selank (tuftsin synthetic analogue)
Mechanism of Action• GABAergic System Modulation: studied for enhancing GABA receptor sensitivity and modulating GABAergic neurotransmission in stress-response pathway research.
• BDNF Upregulation: researched for increasing brain-derived neurotrophic factor (BDNF) levels, supporting neuroplasticity, memory formation, and brain-cell resilience in neurological models.
• IL-6 Suppression & Immune Modulation: studied for downregulating IL-6 (a pro-inflammatory cytokine) and regulating T-helper cell activity in immune-pathway research models.
• Enkephalin Protection: researched for inhibiting enkephalin degradation — protecting the body’s natural opioid-system modulators in pain-pathway research.
Together these make Selank a key tool in GABAergic, BDNF, immune-pathway, and pain-pathway research.

FAQs
GHK-Cu (Glycyl-L-Histidyl-L-Lysine Copper Complex) is a naturally occurring copper-binding tripeptide studied extensively in preclinical and in vitro research models. It is primarily researched for its role in tissue repair, collagen synthesis, wound healing, gene expression modulation, hair follicle biology, and antioxidant defense pathways.
Lyophilized means the compound has been freeze-dried — water is removed under vacuum to produce a stable powder. This process significantly extends shelf life and preserves compound integrity during storage and shipping. Lyophilized peptides are the research-grade standard because they maintain purity far longer than liquid formulations.
Each batch of GHK-Cu is independently verified at ≥99% purity using HPLC (High-Performance Liquid Chromatography). Identity is further confirmed by LC-MS (Liquid Chromatography-Mass Spectrometry). A batch-specific Certificate of Analysis (COA) is available for download before purchase.
Store lyophilized GHK-Cu at −20°C upon receipt. Keep protected from light, heat, and moisture. Do not open the vial until needed for your research protocol. Under proper storage conditions, lyophilized GHK-Cu maintains compound integrity for up to 24 months.
No. Peptides Verse does not provide reconstitution, dosing, or administration guidance of any kind. All reconstitution protocols are the sole responsibility of the qualified researcher or institution receiving this compound. This product is strictly for in vitro and laboratory research use only.
Yes. A batch-specific COA is available for every vial of GHK-Cu sold by Peptides Verse. The COA includes HPLC purity data, LC-MS identity confirmation, lot number, and testing lab details. It can be downloaded directly from the product page before or after purchase.
GHK refers to the free tripeptide (Glycyl-L-Histidyl-L-Lysine) without copper. GHK-Cu is the copper-chelated form — where a Cu² ion is bound to the tripeptide. The copper-chelated form is the biologically active version studied in most published research on wound healing, collagen synthesis, and gene expression modulation.
No. GHK-Cu from Peptides Verse is strictly for in vitro research and laboratory experimentation only. It is not intended for human or animal use of any kind. By purchasing, the buyer confirms they are a qualified researcher or institution and accepts full responsibility for safe handling and use.
All orders are shipped via FedEx with temperature-appropriate packaging to protect compound integrity during transit. Packaging is discreet — plain FedEx or UPS with no product branding on the exterior. Orders placed before 2 PM EST ship same business day.
Due to the nature of research chemicals, all sales are final once a vial has been opened or the seal broken. If you receive a damaged or incorrect item, contact support@peptidesverse.com within 48 hours of delivery with your order number and photos.
