Skin, Hair & Beauty Peptide Strips
Strips built around GHK-Cu, the copper-binding peptide studied in the context of healthy skin structure, plus the KLOW blend that carries it alongside three other compounds. Two SKUs, one shared compound. Both are dietary supplements taken under the tongue — not topicals, and not treatments for any skin condition.

Two things this collection doesn't have
People arrive at a beauty peptide page looking for specific things. Two of them are not here, and we would rather say so on the collection page than let you find out three clicks later.
A dedicated hair peptide
Not stockedThere isn't one in this catalogue. GHK-Cu gets discussed in hair contexts online, but the claim we make for it is skin structure, and we are not going to stretch that into a hair claim to catch the search. If hair is your reason for being here, the honest answer is that we do not have a product for it.
KPV (alpha-MSH tripeptide fragment)
In KLOW onlyKPV shows up in skin-adjacent searches and is one of the four compounds in KLOW at 500 mcg per strip. There is no standalone KPV strip, here or from InstaMed. Human data on it is limited, which is the other reason we cover it as education.
The education pages above are open to everyone and carry no buy buttons.
About this collection
One compound, two ways to buy it
This is a small collection on purpose. GHK-Cu — glycyl-histidyl-lysine bound to copper, a tripeptide that occurs naturally in the body — is the only compound in the catalogue with a genuine claim to this category, and it appears in exactly two products. Beauty carries it alone at 3 mg per tropical-flavored strip. KLOW carries the same 3 mg of GHK-Cu alongside BPC-157, TB-500 and KPV in one strip. That is the whole decision: the single compound, or the same amount of it inside a four-compound blend. We are not going to pad this page with SKUs that do not belong here.
What a copper peptide strip can and cannot claim
The compliant claim for GHK-Cu is that it supports healthy skin structure. That is a structure/function statement, and it is the only kind of claim a dietary supplement may make. It is not a claim that any strip clears a skin condition, reverses anything, or replaces dermatological care — and if you see a peptide seller implying otherwise, that is a reason to leave. Our GHK-Cu education page walks through what the published work actually covers, including how much of it is laboratory and topical rather than oral.
Sublingual versus topical — a real question for this compound
GHK-Cu is unusual in this catalogue because most people meet it first in a serum or cream, not a strip. Those are different routes with different evidence behind them, and one does not substitute for the other. We are not going to tell you a strip outperforms a topical, because nobody has run that comparison for this product. What we can do is set the two side by side honestly — sublingual versus topical GHK-Cu does exactly that, and does sublingual GHK-Cu work covers the state of the evidence for the route itself.
Copper, and the reason to read the label
GHK-Cu is a copper-carrying peptide, which is a reason to look at the rest of what you take rather than a reason for alarm. Copper is an essential mineral with an established upper intake level, and people already taking a copper-containing multivitamin or a separate copper supplement should raise this with a licensed healthcare provider before adding another source. The full ingredient list for each strip is printed on the product page, not buried — that is deliberate, and it is the standard we hold the category to on the safety and sourcing page.
Questions
Skin, Hair & Beauty — common questions
What is the difference between Beauty and KLOW?
Both carry 3 mg of GHK-Cu per strip. Beauty carries only that, in a tropical-flavored film. KLOW adds BPC-157, TB-500 and KPV in the same strip. Same copper peptide, different amount of everything else — the full actives and amounts are listed on the Beauty page and the KLOW page.
Should I use a GHK-Cu strip instead of my serum?
We cannot tell you that, because nobody has compared them for this product. They are different routes: a topical acts where you apply it, a sublingual strip dissolves under the tongue. Plenty of people use both; that is a conversation for you and a licensed provider, not a claim for us to make. The comparison article sets out what is and is not known.
Is the copper in GHK-Cu something to watch?
Copper is an essential mineral with an established upper intake level, so it is worth knowing your total intake across everything you take — particularly if you already use a copper-containing multivitamin. Each strip carries 3 mg of GHK-Cu, and the full ingredient list is on the product page. If you take medication or have a medical condition, talk with a licensed healthcare provider before use.
Can I see the certificate of analysis for my pack?
Yes, where one has been published. Enter the lot number printed on your pack on our COA lookup page and you will get either the certificate we hold for that lot or a plain statement that no COA has been published for it yet, with a way to request one. We do not show a certificate from a different lot and call it yours.
