GHK-Cu from $34.99 BPC-157 from $34.99 ## Price snapshot ### GHK-Cu Current low $34.99 current listings 7-day low — not enough history yet 30-day low — not enough history yet 30-day change — not enough history yet ### BPC-157 Current low $34.99 current listings 7-day low — not enough history yet 30-day low — not enough history yet 30-day change — not enough history yet ## GHK-Cu GHK-Cu is the copper(II) complex of the tripeptide glycyl-L-histidyl-L-lysine, a molecule Pickart and Thaler first pulled out of human plasma in 1973.

Injectable use is preclinical/off-label, research-use-only, with no human clinical trials. | Preclinical | | Mechanism of Action | GHK-Cu works mostly as a copper shuttle and a signaling peptide. It binds Cu(II) with high affinity (log K around 16.4, close to albumin's 16.2) and can supply or regulate copper for copper-dependent enzymes like SOD1, lysyl oxidase, cytochrome c oxidase, and… | Nitric Oxide (NO) System Modulation BPC-157 exerts a central integrative effect through modulation of the nitric oxide system. Studies by Seiwerth et al. (2022) demonstrated that BPC-157 counteracts both NO-excess and NO-deficiency states, functioning as a… | | Half-Life | ~30-60 min (plasma; approximate legacy figure, no robust modern human PK study) | Short plasma half-life. The first formal preclinical ADME study reported an elimination half-life under ~30 minutes after IV/IM dosing in rats and dogs, with linear dose-proportional kinetics (PMID: 36588717); a 2026 biopharmaceutical review confirms this sub-30-minute plasma half-life and highlights a pharmacokinetic-pharmacodynamic disconnect, as biological effects persist for hours to days (PMID: 42198317). No full human pharmacokinetic study has been published; twice-daily dosing is empirical/community-standard rather than PK-derived. | | Typical Dose Range | 200-500 mcg SC daily (community/RUO; no clinically established injectable dose) | 200-500 mcg subcutaneous 1-2x daily (community protocols); 1-10 mcg/kg in animal studies | | Dosing Frequency | Once daily subcutaneous; some run 5 days on / 2 days off. Topical: 1-2x daily to cleansed skin. | Twice daily (AM and PM) for optimal serum levels; once daily acceptable | | Administration | Subcutaneous, Topical | Subcutaneous, Oral, Intraperitoneal, Intravenous | | Side Effects | Topical GHK-Cu is generally well tolerated; higher-concentration formulations (4-5%) raise the odds of irritation, redness, or stinging. Injectable use has no safety data from controlled trials; the main theoretical concern is copper accumulation with repeated… | Generally well-tolerated. Mild nausea or GI discomfort during initial use. Temporary increase in pain/inflammation at injury site (healing response). Rare: drowsiness, dizziness, mild headache. Very rare: transient changes in blood pressure. | | Molecular Weight | Free peptide (GHK): 340.38 Da (C14H24N6O4). Copper complex (GHK-Cu): 401.9 Da (C14H22CuN6O4, neutral 1:1 Cu(II) complex). | 1419.5 g/mol (average); molecular formula C62H98N16O22 | | Common Vial Sizes | 50 mg, 100 mg | 5mg, 10mg | ## Price History 4 data points - OF - BM - Half Nattys - BHG Labs ## Price History 7 data points - OF - BM - Half Nattys - LB - Ion Peptide - BHG Labs ### GHK-Cu: potential benefits - Stimulates type I collagen synthesis in human fibroblasts at low nanomolar-to-picomolar concentrations (PMID: 3169264) - Increases glycosaminoglycans (dermatan/chondroitin sulfate) and upregulates decorin in wound models (PMID: 11121126) - Modulates matrix metalloproteinases and their inhibitors, partially correcting the MMP-9/TIMP-1 imbalance in a smoke-induced emphysema model (PMID: 35936787) - Drives tissue remodeling and chemoattracts macrophages, mast cells, and capillary cells to injury sites (PMID: 18644225) - Modulates expression of ~4,000+ human genes via the Broad Institute Connectivity Map, including DNA-repair and antioxidant genes (PMID: 25302294) - Increases stemness and proliferative potential of epidermal basal cells and keratinocytes (PMID: 23019153) - Acts as an antioxidant and anti-inflammatory copper regulator in the context of aging (PMID: 22666519) - Broad skin-regeneration effects on collagen, proteoglycans, MMPs, and immune/endothelial cell recruitment (PMID: 26236730) ### BPC-157: potential benefits - Accelerated tendon and ligament healing with improved biomechanical strength in preclinical soft-tissue injury models (PMID: 30915550) - Gastric and GI mucosal cytoprotection against ethanol-induced lesions, mediated in part by the nitric oxide system (PMID: 30279308) - Healing of cysteamine-induced colitis and colon anastomosis in preclinical inflammatory bowel disease models (PMID: 24304574) - Neuroprotection with dopaminergic and nitric oxide-system modulation in central nervous system injury models such as stroke and dopamine-receptor blockade (PMID: 34380875) - Promotion of angiogenesis via VEGFR2 up-regulation, internalization, and VEGFR2-Akt-eNOS signaling in rat hind-limb ischemia and endothelial assays (PMID: 27847966) - Tendon fibroblast outgrowth, cell survival, and migration through FAK-paxillin pathway activation (PMID: 21030672) - Growth hormone receptor up-regulation in tendon fibroblasts, potentiating growth hormone's proliferative effect (PMID: 25415472) - Nitric oxide-system interaction with endothelium protection, angiogenesis, and EGR-1-mediated growth-factor and collagen expression (PMID: 22300085) ## Frequently asked ### What's the difference between GHK-Cu and BPC-157?
