GHK

This is not GHK-Cu– see another discussion for GHK-Cu.

A lot of the clinical benefits of GHK are enhanced with the Cu, so if you eliminate the Cu you might not get the same benefits that you had hoped for compared with GHK-Cu.  Using just GHK will likely require more serum copper support.

To use GHK topically:

If your GHK is lyophilized freeze dried powder in a vial, you should first reconstitute it in the same way as you would GHK-Cu.  If it came in a 3cc vial, you will only be able to put 3cc of BAC water in.  100mg vial with 3cc BAC will equal 3.33mg per 10 units.

At this point, you can further reconstitute it into a simple carrier — an unscented, fragrance-free lotion or gel base, or even diluted further in bacteriostatic water for a spray/mist application.  Apply to clean, dry skin. Common areas of interest: face, scalp, or localized scarring/healing sites.

To use subcutaneously:

Injecting GHK, without the copper “Cu”, doesn’t sting like injecting GHK-Cu does.  This is the route most peptide users default to when they want more predictable systemic exposure rather than relying on topical penetration.

GHK was originally isolated from human plasma specifically because of its extraordinarily high binding affinity for Cu²⁺ — it binds copper more tightly than albumin does, which is the main copper-carrying protein in blood. This is actually why Pickart’s early research treated GHK and GHK-Cu somewhat interchangeably; free GHK introduced into a copper-containing environment (like blood) has a strong tendency to scavenge loosely-bound or exchangeable copper and form the complex in situ, rather than staying as bare peptide.

So injecting “plain” GHK subq isn’t necessarily injecting something that stays functionally distinct from GHK-Cu — it may pick up copper from your own serum copper pool (normally a small but real free/exchangeable fraction, distinct from ceruloplasmin-bound copper) shortly after administration. Whether it picks up enough to replicate a deliberately-dosed GHK-Cu complex is genuinely unclear and not something with good human data — but it’s not automatically “inert” in the way, say, an unrelated random peptide with no metal affinity would be.

The in vitro literature that separates “GHK-alone” from “GHK-Cu” effects does show differences — some gene expression and wound-healing assays behave differently depending on whether copper is bound, suggesting the copper really matters mechanistically, not just as a delivery gimmick. 

There’s a real chance GHK will behave partially like GHK-Cu once in circulation. But it’s also not a confident substitute; you’re relying on your own serum copper to do the complexing job that manufacturing normally does deliberately and controllably. If you want to hedge toward that outcome rather than leave it to chance, that’s really the only place where oral or dietary copper timing might matter — not combined in the vial, but ensuring you’re not copper-deficient at the time of injection, since a copper-replete state is the mechanism by which it could self-complex at all.

Bottom line: 

Take copper supplements when taking GHK (and not GHK-Cu).

The RDA for copper is 900 mcg/day for adults. Most people already get 700–1,500 mcg/day from a normal diet (organ meats, shellfish, nuts, seeds, dark chocolate, whole grains all have meaningful copper). The tolerable upper limit is 10,000 mcg (10 mg)/day. That’s a wide margin — you’re not threading a needle between deficiency and toxicity, you’re just making sure you’re not on the low end.

Practical approach without bloodwork:

• A modest supplement — 1–2 mg/day (1,000–2,000 mcg) — taken for a few days to a week before you plan to use the GHK would reasonably ensure you’re not copper-depleted, without approaching the 10 mg UL by a wide margin.
• You don’t need to supplement continuously — copper stores in the liver, so a short loading period before injection is a more sensible approach than daily long-term dosing, and it limits your cumulative exposure.
• Copper bisglycinate or copper gluconate are generally better tolerated on the GI tract than copper sulfate, if you have a choice.
• Take it separately from zinc or high-dose vitamin C supplements if you take those, since both interfere with copper absorption.

Symptom self-monitoring as your safety net (without doing bloodwork):

Given the wide margin between RDA and UL, at 1–2 mg/day you’re very unlikely to see any toxicity symptoms of too much copper. But as a practical check: watch for nausea, GI upset, or metallic taste in the days you’re supplementing — those would show up well before anything more serious, and they’re your signal to stop, not push through.

One more consideration:

Don’t take the copper supplement and inject the GHK at the exact same time expecting instant complexation — the idea is that day(s)-prior supplementation gives your serum/exchangeable copper pool a chance to be adequately stocked, so it’s available when the GHK is circulating, not that the two need to coincide to the hour.

This seems like a reasonable, low-risk way to give your GHK a real shot at behaving more like GHK-Cu, without the expense of testing or the complexity of trying to pre-form the complex yourself.
