The Molecula Standard
Every milligram,
accounted for.
Most suppliers publish a purity percentage. A vial can be 99% pure and 78% full. We publish the measured net peptide content of every lot. Our 10 mg ML-RT assayed at 12.11 mg. Our 50 mg GHK-Cu came back 53.65 mg. If a lot ever comes in under label, we credit the difference back to everyone who bought it.

Promise, proof, process
The Molecula Standard
Anyone can put a badge on a website. These are three things you can check yourself — on our numbers, on our paperwork, and on the lot in your hand.
01 — THE PROMISE
Full Fill Guarantee
You pay for peptide, not powder.
Every lot we test is assayed for net peptide content, not just purity. If a lot measures below its label weight, every buyer of that lot is credited the difference — automatically, with an email explaining why. You do not have to notice, and you do not have to ask.
A 10 mg vial that assays at 9.2 mg means 8% back.
02 — THE PROOF
Lot Passport
Every vial has a lot number. Type it in.
Enter the lot number from your vial and get the whole file: purity, measured net content, assay method, the lab, the accession number, the report date and the full COA. No account, no email gate, no "contact us for a COA".
A claim you can check beats ten you can't.
03 — THE PROCESS
Lot Drops
Watch your lot get made.
Nothing sits on a shelf going stale. Every vial belongs to a lot of ten, and the product page tells you which lot yours comes from and how much of it is left. The lot is tested and its certificate published before anything ships — and pre-order costs less than in-stock, because you waited.
No lot ships until its certificate is published.
Lot Passport
Every lot we have published
The lot number is printed on your vial label, your packing slip and your shipping email — and the QR on the label takes you straight to that batch's certificate.

Nothing sits on a shelf
going stale.
Most suppliers guess how much to hold, then sell you whatever has been sitting longest. We buy in lots of ten and tell you exactly which lot your vial came out of, what it assayed at, and how much of that lot is left. Made to order, tested, published, shipped.
- Every vial belongs to a lotTen vials to a lot, because a box is ten. Nothing gets split across batches and nothing sits around.
- You can see which lot is yoursA live counter on the product page shows the lot number and how many vials of it are left.
- That lot goes to the labIdentity, purity and net peptide content. Not a sample of the range — that lot.
- The certificate publishes firstThe COA goes up under its lot number before a single vial leaves.
- Then it ships, on the normal timeline3–5 business days to make and test, 1–2 in transit. You never wait on another customer's order.
Pre-order costs less than in stock. On purpose.
Made to order means we buy a full box and nothing is wasted, so we price it that way — the vials we hold ready to ship cost more than the ones you wait a few days for. Most stores charge a premium for pre-ordering. We think that is backwards.
