In this video, I walk through the simple dilution trick that completely fixed my GHK‑Cu injection‑site problems.
When I first started using GHK‑Cu, every shot left me with:
- Strong burning at the injection site
- Redness and local irritation
- Small, raised welts that lasted for hours
The solution wasn’t changing the peptide – it was changing how concentrated it was when it hit the tissue.
Here’s what I do now, step‑by‑step, in the video:
1. Draw the GHK‑Cu dose first
- I pull up my normal GHK‑Cu dose into an insulin syringe (for example, 2–4 mg worth based on how I mixed the vial).
- At this point, the peptide is very concentrated and was exactly what caused the burning before.
2. Dilute it directly in the syringe with bacteriostatic water
- Without injecting anything yet, I draw extra BAC water into the same syringe
- This increases the total volume while keeping the same GHK‑Cu dose, so the peptide is less concentrated per mL and much gentler on the tissue.
- I gently tap/roll the syringe so the GHK‑Cu and BAC water mix evenly. No shaking, just enough to blend.
3. Inject the diluted solution slowly
- I inject subq as usual, but at this point the solution is significantly diluted.
- The result:
- Almost no burn
- Minimal redness
- No big welts or “bee sting” feeling afterward
Key idea: same dose, lower concentration, slower injection. That single change turned GHK‑Cu from one of the most uncomfortable shots in my stack into a completely tolerable nightly peptide.
If you’ve had stinging or irritation from GHK‑Cu, this video walks you through exactly how to dilute it in the syringe so you can keep the benefits without dreading every injection.
MISTAKE ALERT Sorry for the mistake, I only wanted 45 units in the syringe, not 55. I misspoke 🤦🏼‍♂️
