An independent intelligence board aggregating credible research, preprints, clinical findings, biohacking experiments, and community discussions on therapeutic peptides, longevity science, and evidence-based anti-aging. Stories are scored for relevance, credibility, novelty, momentum, and practicality so the most important findings surface first.
Someone on a forum is trying to work out how much GHK‑Cu they’re injecting and asking if their math is right. They say they have 100 mg of GHK‑Cu powder in a 3 ml vial after adding bacteriostatic water, and they plan to draw 0.5 ml per shot with a 0.5 ml syringe. They think each 0.5 ml dose equals 1,000 micrograms (mcg) and that taking two shots a day would be 2,000 mcg. They also mention taking another “wolverine blend” that delivers 500 mcg twice daily, so they believe the combined total would be 1,000 mcg from that blend plus the GHK‑Cu they calculated. GHK‑Cu is a small peptide (a tiny chain of amino acids) that naturally occurs in the body and binds copper. In some research and cosmetic uses it’s touted for wound healing, skin regeneration, and anti‑aging effects. It’s sold in research and cosmetic markets, and some people use it off‑label or in DIY regimens. It’s not a vitamin or a hormone — think of it as a tiny biological signal that can affect cells when given at certain doses. Let’s be clear about the math: if you truly have 100 mg (that’s 100,000,000 micrograms) in a total volume of 3 ml, each 1 ml would contain 33.33 mg (33,333,333 mcg), and each 0.5 ml would contain about 16.67 mg (16,666,667 mcg). That is vastly larger than 1,000 mcg. So either the poster meant 100 micrograms (mcg) total, 1000 micrograms, or they misread units. A common correct calculation example: if you had 100 mg in 30 ml, then 0.5 ml would be 1.67 mg (1,667 mcg). Always keep track of units (mg vs mcg) and total volume. If you’re unsure, double‑check the vial label and redo the arithmetic slowly: (total amount in mcg) ÷ (total volume in ml) × (dose volume in ml) = dose per injection in mcg. Why this matters: dosing errors with peptides can be either pointless (not enough to have any effect) or risky (too much could cause unwanted effects). People taking multiple products simultaneously need to be sure they’re not unintentionally stacking similar active ingredients and vastly overdosing. If you’re using these products for skin, wound healing, or “anti‑aging,” accurate measurement affects whether you’ll see any benefit and whether you could face side effects. Caveats: GHK‑Cu is not approved as a general injectable drug for anti‑aging by major regulators. Quality, concentration, and purity can vary between suppliers. Injecting peptides carries infection and irritation risks if not done sterilely. Side effects reported anecdotally include local irritation, and long‑term safety and optimal dosing aren’t well established. If the math or labelling is unclear, don’t inject; ask the seller for clarification, consult a clinician, or have a pharmacy compound or verify the product. Bottom line: double‑check units and volumes before dosing — a simple unit mistake can change your dose by thousands of times.
