Helloskin vs RegenMed Direct
RegenMed Direct lists an impressive peptide roster — GHK-Cu, an EGF growth factor, SNAP-8, Matrixyl Synthe'6 — and it includes Niacinamide. Genuine variety. But the only percentage they disclose is 0.5% GHK-Cu — less than half ours — every other dose is a mystery, there's no antioxidant, and no bottle size is even stated. We declare a full 9% peptide system with 1.2% GHK-Cu, at a size you can see, scored 9.6/10 on a ChatGPT ingredient scan. Here's the breakdown — no spin, just chemistry.
Five peptides on the label, one dose disclosed — and it's half of ours.

A longer list, or a declared dose?
RegenMed Direct's roster is genuinely varied — five peptides including an EGF growth factor. But a list of names isn't a formula you can judge. Of all those peptides, only one percentage is on the label: 0.5% GHK-Cu. We keep the list tighter and put every dose on the record.
peptide doses disclosed
GHK-Cu, EGF (sh-Oligopeptide-1), SNAP-8, Matrixyl Synthe'6 and Tetrapeptide-7 are all listed — but only 0.5% GHK-Cu is stated, and there's no antioxidant to protect any of it. Variety you can't verify.
every peptide declared
1.2% GHK-Cu + 5% Palmitoyl Tripeptide-1 + 3% Palmitoyl Tetrapeptide-7 — Matrixyl 3000 — all declared, antioxidant-protected, in a stated 30ml. You know exactly what you're applying.
Credit where it's due: an EGF growth factor and SNAP-8 are actives we don't carry, and they add Niacinamide. But for a serum sold on "GHK-Cu", 0.5% is less than half our dose — and everything past it is undisclosed.
What's on the record.
You can only judge the doses a brand is willing to publish. Here's what each label actually declares.
RegenMed Direct genuinely has more peptide types, and an EGF growth factor we don't offer. But a broader list at undisclosed doses — with only 0.5% GHK-Cu on the record — tells you less than a tighter one where every gram is declared.
We ran our formula through a ChatGPT ingredient scan.
The prompt: "Scan this like a shopper comparing GHK-Cu serums, using the INCI list and confirmed peptide percentages." Because every dose is declared, there's something real to score.
"A genuinely serious copper peptide serum"
In its words: "not one where the peptides are buried at tiny marketing levels — with 1.2% verified GHK-Cu and 9% total peptides, this sits in a genuinely premium performance category."

All 15 categories. Scored fairly.
Helloskin wins 11, ties 1, cedes 3. RegenMed Direct genuinely wins peptide variety, its EGF growth factor and an expression-line peptide. Credit where it's due.
Every ingredient. Both labels, side by side.
RegenMed Direct's list is peptide-rich — but the only concentration published is 0.5% GHK-Cu.
What RegenMed Direct gets right.
More than most. This is a genuinely peptide-rich formula: alongside GHK-Cu it carries an EGF growth factor (sh-Oligopeptide-1), the expression-line peptide SNAP-8, and Matrixyl Synthe'6 — actives we don't offer — and it includes Niacinamide and hyaluronic acid. If you specifically want a growth-factor-and-multi-peptide serum, that variety is a real point of difference.
Where we pull ahead is dose and disclosure. For a serum sold as "GHK-Cu", 0.5% is less than half our 1.2%, and it's the only percentage on the label — every other peptide, including that EGF, is undisclosed. There's no antioxidant to protect a copper peptide that oxidises, no soothing botanicals, and no bottle size stated, so you can't even judge value. We publish a 9% peptide system to the decimal, protect it, and tell you it's 30ml for $89.99. Variety is good; a dose you can trust is better.
