We started becausenobody would tell us how much was in the bottle.
A trace is enough to make the claim. There's no minimum. A brand can include a fraction of a percent of an active and put it on the front of the bottle in large type, entirely legally. The research they cite in the marketing was run at concentrations they're nowhere near, but you'd have to go looking to know that.
We would rather you didn't have to look.
Peptides are expensive. A trace amount lets you put the ingredient on the label without spending much on it, and no rule says you have to disclose the quantity. So almost nobody does.
That isn't fraud. It's a gap between what a label implies and what's in the bottle — and it's a gap the buyer has no way to close.
GHK-Cu 3% Topical Serum
All Products are 3rd Party Tested
One active per product, at a concentration that justifies its place, printed on the label so you can hold it against anything else you own.
No fifteen-ingredient blends. No proprietary complexes. Each formula does one job, and tells you exactly how much it's bringing to it.
We'd like disclosure to become normal. Not a marketing angle, normal. The kind of thing a shopper expects, the way a nutrition panel is expected on food.
Until then, we'll keep printing ours and inviting the comparison.
