Full Cordyceps profile (https://www.bodyhackguide.co/compound/cordyceps) ## 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. 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 | Cordyceps | GHK-Cu | | --- | --- | --- | | Category | Adaptogen | 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 | Cordyceps exerts its effects through multiple overlapping mechanisms centered on ATP/adenosine pharmacology, cordycepin's nucleotide analog activity, β-glucan immune modulation, nitric oxide enhancement, and antioxidant/anti-inflammatory pathways. The relative… | 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 | — | ~30-60 min (plasma; approximate legacy figure, no robust modern human PK study) | | Typical Dose Range | — | 200-500 mcg SC daily (community/RUO; no clinically established injectable dose) | | Dosing Frequency | — | Once daily subcutaneous; some run 5 days on / 2 days off. Topical: 1-2x daily to cleansed skin. | | Administration | — | Subcutaneous, Topical | | Side Effects | Cordyceps is generally well tolerated at typical supplemental doses, with one of the better safety profiles among fungal supplements. Most reported side effects are mild and transient. Common side effects (1-10%): - Mild gastrointestinal upset — nausea, loose… | 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 | — | Free peptide (GHK): 340.38 Da (C14H24N6O4). Copper complex (GHK-Cu): 401.9 Da (C14H22CuN6O4, neutral 1:1 Cu(II) complex). | | Common Vial Sizes | — | 50 mg, 100 mg | ## Price History 4 data points - OF - BM - Half Nattys - BHG Labs ### Cordyceps: potential benefits - No structured benefit list published. ### 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 Cordyceps and GHK-Cu? Cordyceps is a adaptogen that cordyceps exerts its effects through multiple overlapping mechanisms centered on atp/adenosine pharmacology, cordycepin's nucleotide analog activity, β-glucan immune modulation,…. GHK-Cu is a skin, hair & aesthetics that 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…. The two differ in mechanism, half-life (not reported vs ~30-60 min (plasma; approximate legacy figure, no robust modern human PK study)), and typical dose range. ### Which has the longer half-life, Cordyceps or GHK-Cu? Cordyceps has a half-life of not reported. GHK-Cu has a half-life of ~30-60 min (plasma; approximate legacy figure, no robust modern human PK study). Longer half-lives generally mean less frequent dosing but slower on/off kinetics. ### Can you stack Cordyceps and GHK-Cu? Stacking depends on mechanism overlap, safety profile, and goals. Cordyceps and GHK-Cu should only be stacked after reviewing each compound's individual protocol page, side effect profile, and any published interaction data.
