The peptide you're after. Nothing else.

GHK-Cu and AHK-Cu in a plain cream or serum base, made in small batches in Auckland. No extra actives padding out the ingredient list, no fancy packaging, no BS. Just the strength and the milligrams on the label, and a certificate of analysis for every batch.

The Sine Cera range: two amber pump-bottle serums and two amber jars of cream

Shop by active ingredient.

Pick the molecule, then pick cream or serum. Every label states the percentage and the milligrams in the container.

Any two products are 10% off and three or more are 15% off, worked out in the cart.

What's in the jar is what's on the label.

Most creams list a peptide somewhere in the ingredients and leave it at that. We print the percentage and the milligrams on the front, and the batch number on the label leads to a certificate of analysis on this site.

The packaging is plain on purpose. You're paying for the peptide.

The strength, as a percentage
1% GHK-Cu means 1 gram of copper tripeptide-1 in every 100 grams of product.
The amount, in milligrams
600 mg in a 60 mL jar, 300 mg in a 30 mL bottle. No working it out yourself.
The batch it came from
Look the batch number up on the batch COA page to see the peptide lot behind it.
Sine cera

Latin for "without wax". The story goes that Roman sculptors who sold honest marble marked it sine cera, meaning no wax was hiding the cracks. That's the idea here: the molecule, the strength and the batch, nothing filled in. No BS marketing or expensive packaging served with a ridiculous markup.
