2.75 mg
Research details
KLOW Stack is a fixed multi-peptide blend supplied as a single lyophilized vial that combines four research peptides at a set ratio: GHK-Cu 25mg + TB-500 10mg + BPC-157 10mg + KPV 10mg per vial (55 mg total mass). KLOW is a vendor-coined blend name rather than a standardized formulation, and it is offered strictly for research use only. The same concept minus KPV is marketed as GLOW, so KLOW can be read as GLOW plus the alpha-MSH-derived anti-inflammatory tripeptide KPV.
The blend thesis behind KLOW is that its four peptides address complementary, largely non-overlapping nodes of tissue-repair biology, so a single vial covers angiogenesis, matrix remodeling and inflammation together in preclinical models. The component science is dose-independent, but the per-mL concentration after reconstitution depends on the exact vial loading.
KLOW combines four structurally and mechanistically distinct peptides in a 25 : 10 : 10 : 10 ratio. Because it is a fixed blend, the four components cannot be dosed separately, and pharmacokinetics are component-specific rather than blend-wide.
KLOW Stack is available in three pack sizes so research workflows can scale supply to the experiment without repeat ordering.
Each batch is supported by HPLC purity verification and a Certificate of Analysis (CoA), with quality-control documentation available so researchers can confirm identity and purity before use.
Bergdorf Bioscience ships KLOW Stack worldwide with discreet, tracked packaging and temperature-aware handling. Lyophilized vials are stable for shipping; store frozen at -20 C for long-term holding, and after reconstitution with bacteriostatic water refrigerate at 2 to 8 C and use within about 28 to 30 days. For research use only, not for human consumption.
GHK-Cu: copper-dependent collagen synthesis and matrix remodeling; TB-500: actin polymerization and cell migration; BPC-157: NO pathway modulation and angiogenesis; KPV: NF-κB inhibition via α-MSH fragment activity.
Advanced protocol
As directed per research protocol (contains 4 active components)
Note: The dosages listed correspond to typical ranges from published research literature. They do not replace advice from a qualified researcher or physician.
Every batch is analyzed by an independent laboratory via HPLC before shipment. We document purity (avg. 99.43% in 2026), mass spectrometry identity, and sterility. Production follows GMP standards in ISO-certified laboratories.
