27 peptides, priced per milligram. These are the peptides for sale that PeptideDeck links to: single vials and blends from $40 to $120, each listed with its vial size, the current price, the price per mg and the purity of the tested batch.

Buying peptides online is mostly a trust problem. The same name on two websites can mean two very different vials. So the checks that matter are simple: is there a certificate of analysis for your batch, where does it ship from, and is the price believable?

Every card below opens a product page with the vial details, the batch COA where the vendor publishes one, and what to check before you order. Code PEPTIDEDECK takes 50% off at checkout.

How to Choose Peptides for Sale Online

Four checks catch most bad vials before you pay. If a seller fails one, buy somewhere else.

  1. 01

    A COA for your batch

    Purity by HPLC, identity by mass spec, a named lab and a batch number that matches the vial.

  2. 02

    Purity of 98% or more

    Below that, a meaningful share of the powder is something other than the peptide you paid for.

  3. 03

    US shipping and storage

    Domestic stock arrives in days, not weeks in customs, which matters for a powder that dislikes heat.

  4. 04

    A believable price

    Use the price per mg. A vial at a third of everyone else's price is usually short-filled or mislabeled.

Peptides for Sale: FAQ

How much do peptides cost?

On this page, from $40 (Melanotan II) to $120 (KLOW Blend) per vial. Vial sizes differ a lot, so compare the price per milligram on each card rather than the sticker price. Code PEPTIDEDECK takes 50% off at checkout.

How do I know a peptide is what the label says?

Ask for the certificate of analysis (COA) for the batch you will receive. It should show HPLC purity above 98%, a mass-spec result matching the peptide's molecular weight, the lab's name and a batch number that matches your vial. A generic COA with no batch number proves nothing. How to read a peptide COA

Is it legal to buy peptides online?

In the US most of these peptides can be bought online without a prescription, but they are sold as chemicals, not as approved medicines, so no agency checks the vial before it ships. A few have prescription versions through a doctor, such as tesamorelin (Egrifta) and bremelanotide (Vyleesi). The rules for compounding pharmacies changed in 2026. Are peptides legal? The 2026 rules

Not medical advice. Peptides sold online are not reviewed by the FDA the way prescription medicines are. Talk to a doctor before using any peptide, especially if you take prescription medication, are pregnant or have a medical condition. Prices and stock change; check the seller's page before you order.
