The free peptide (GHK, C14H24N6O4) weighs about 340.4 Da; bind it 1:1… **Lowest listed price:** $34.99 across 7 listings Full GHK-Cu profile (https://www.bodyhackguide.co/compound/ghk-cu) ## Side-by-side comparison | Attribute | BPC-157/TB-500 Blend | GHK-Cu | | --- | --- | --- | | Category | Recovery | Skin, Hair & Aesthetics | | Research Stage | Preclinical | Approved/marketed as a topical cosmetic ingredient (Copper tripeptide-1) with supporting small human studies. Injectable use is preclinical/off-label, research-use-only, with no human clinical trials. | | Mechanism of Action | A combination of BPC-157 and TB-500 (thymosin beta-4) in a single formulation. It pairs BPC-157's angiogenic, pro-healing activity - driven largely through VEGFR2 and nitric-oxide (Akt-eNOS) signaling (PMID: 40789979) - with TB-500's actin… | 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… | | Half-Life | BPC-157: short - under ~30 min in animal PK studies (rats/dogs); no human PK data. TB-500 (thymosin beta-4): active fragment ~30 min, though tissue effects are prolonged. | ~30-60 min (plasma; approximate legacy figure, no robust modern human PK study) | | Typical Dose Range | Dosed per component (a fixed daily blend over-doses TB-500 - see notes). BPC-157: 250-500 mcg once daily SUBQ. TB-500 (thymosin beta-4): 2-2.5 mg twice weekly during a 4-6 week loading phase, then 2-2.5 mg once weekly for maintenance (~5 mg/week during loading). If a pre-blended fixed-ratio daily vial is used, its TB-500 fraction should be ~250-350 mcg per injection so the weekly TB-500 total stays near ~5 mg. | 200-500 mcg SC daily (community/RUO; no clinically established injectable dose) | | Dosing Frequency | BPC-157: once daily SUBQ. TB-500: twice weekly during the loading phase, then maintenance ~2-3x/week or once weekly for TB-500 as needed. | Once daily subcutaneous; some run 5 days on / 2 days off. Topical: 1-2x daily to cleansed skin. | | Administration | Subcutaneous, Intramuscular | Subcutaneous, Topical | | Side Effects | See individual compounds. Generally well-tolerated. Injection site reactions, mild nausea, headache. Rare: temporary fatigue. | 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… | | Molecular Weight | BPC-157: ~1419.5 g/mol (average; molecular formula C62H98N16O22). TB-500 (thymosin beta-4): ~4963 Da (full 43-residue peptide). | Free peptide (GHK): 340.38 Da (C14H24N6O4). Copper complex (GHK-Cu): 401.9 Da (C14H22CuN6O4, neutral 1:1 Cu(II) complex). | | Common Vial Sizes | 5mg, 10mg | 50 mg, 100 mg | ## Price History 4 data points - OF - BM - Half Nattys - BHG Labs - RC ## Price History 4 data points - OF - BM - Half Nattys - BHG Labs ### BPC-157/TB-500 Blend: potential benefits - Accelerated tissue healing (preclinical/anecdotal) - Reduced recovery time - Anti-inflammatory support - Complementary repair mechanisms: angiogenesis (BPC-157) plus actin-regulated cell migration (TB-500) ### 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) ## Frequently asked ### What's the difference between BPC-157/TB-500 Blend and GHK-Cu?
