We dispatch from Florida in 1–2 business days. Transit after that depends on the destination within the United States. Free shipping over $100.

The batch number is printed on the vial label, not on a separate sticker. That number lives in the COA registry with its purity, its method and the lab that measured it once the certificate is out.

No. Bacteriostatic water is ordered separately or in a pack, where it comes out cheaper than buying them individually and arrives in a single shipment.

Refrigerated. It's printed on every vial label. The lyophilized powder handles transit at room temperature without issue.

You have 30 days. If the vial arrived broken, with an unreadable label, or the batch doesn't match the registry, we replace it at no cost. Email us your order number and a photo.

The vial ships lyophilized. You add bacteriostatic water, and the concentration depends on how much you add. Run the numbers here:

Resulting concentration: —

That's just the arithmetic of the solution. One 10 ml water vial covers several peptide vials.

Inside the vial

One dual agonist, broken down

GIP

GIP receptor

Glucose-dependent insulinotropic peptide

One of the two axes it works on.

GLP-1

GLP-1 receptor

Glucagon-like peptide-1

The most studied of the incretin class.

A single 20 mg peptide. The bar represents the two receptors, not a mix of compounds.

About this compound

What's in the vial and how it's documented

Synthetic peptide: dual agonist of the GIP and GLP-1 receptors. CAS 2023788-19-2, formula C225H348N48O68, molecular weight 4813.45 g/mol.

Each vial holds 20 mg of lyophilized powder with its batch number printed on the label. It ships undiluted.

Every batch goes out for independent testing. When the certificate comes back it's published in the COA registry, linked to the batch number on your label. Until then it's listed as pending: we'd rather show the gap than invent a number.
