GHK-Cu by injection carries no price here. The lawful forms do: a typical $134 a month for the topical, across 34 sellers. The reason is a route exclusion written into the federal list. It is worth reading in full.

What the two federal lists actually say
The 503A list carries the entry “GHK-Cu (except for injectable routes of administration)” in Category 1[1]. The parenthesis is the whole answer.
That wording arrived by a specific route. FDA took GHK-Cu off Category 1 on April 22, 2026, because the nominations were withdrawn[1].
One nominator wrote back on May 5, 2026. It had meant to withdraw only the injectable route[1]. The non-injectable entry went back on the list[1].
The outsourcing-facility list is the other door, and it is shut too. The 503B categories, updated March 21, 2025, name no form of GHK-Cu or copper tripeptide anywhere[2].
A 503A pharmacy has an interim policy covering the non-injectable routes only. A 503B facility has no listed route at all. The split is set out in 503A vs 503B.
FDA's stated reason for the exclusion
FDA files GHK-Cu for injectable routes under bulk substances nominated but withdrawn[3]. It gives a reason there.
Compounded injectable GHK-Cu may pose a risk of immunogenicity, from aggregation and peptide-related impurities[3]. Human data are limited[3].
Category 1 is not an approval either. It is an evaluation, and FDA says so in its own interim policy[4]. The agency does not intend to act against compounding from a Category 1 substance while that evaluation runs[4].
Sellers advertise the shot anyway
Of the 79 tracked sellers carrying GHK-Cu, 2 publish an injectable product. Those prices are held out of every figure on this site.
The rule is mechanical, not editorial. The compound register scopes GHK-Cu to non-injectable routes, and each price is gated on that scope before it can count.
One consequence is worth naming. A quote for an injectable vial cannot be compared with the board, because the board prices a different product.
What the lawful forms cost
| Topical | Swallowed | Under the tongue | Injection | |
|---|---|---|---|---|
| Sellers publishing a month | 34 | No market | No market | Not priced here |
| Lowest published month | $69 | No market | No market | Not priced here |
| Typical (median) month | $134 | No market | No market | Not priced here |
| Highest published month | $209 | No market | No market | Not priced here |
Only the topical route has enough priced sellers for a market. The swallowed and sublingual products exist, but at two or three sellers a figure is a coincidence, not a price.
A jar is also not a month. Turning a container into a monthly figure is worked through in GHK-Cu cost. The cosmetic version of the same product is priced in copper peptide serum.
What the published record contains
GHK is a three-amino-acid sequence found in human plasma, saliva and urine, and it declines with age[5]. It is proposed to act as a complex with copper[5].
That review comes from a skincare company’s own research department, which is worth knowing when reading its claims[5].
A 2026 sports-medicine review places GHK-Cu among peptides sold direct to patients outside the approval process[6]. Its summary of that whole group is that rigorous human safety data are scarce[6].
The search record is the plainer answer. PubMed indexes 180 GHK-Cu records. Twenty mention an injected route. Three are randomized trials, and all three applied it to the skin or tested it in animals.
Restrict the search to human studies using a subcutaneous, intravenous or intramuscular route and nothing comes back at all.
Three questions before paying for a vial
- Which route is the product, and does the pharmacy name its compounding category?
- What is the concentration, and how many days does one container last at the stated use?
- Does the quoted price include the consult, and what does month two cost?
The last one moves the bill most. Fees outside the headline price are listed in peptide therapy cost. The wider buying question is covered in where to get peptides.
