How much does peptide testing cost?

Straight answer first: independent testing of one research peptide vial — identity, chromatographic purity, and net-peptide content — costs $150 at our bench, dropping to $125/vial at 5 vials and $100/vial at 10. Bacteriostatic water is a flat $75. Here's what that money buys, what moves the number, and where the cheaper options quietly cut.

The price list

Per vial with one active, standard turnaround included. Blends and rush are covered below.

The price is charged for each vial, not once per product or lot. Each vial is one test and gets its own certificate, so two vials of the same product are two lines on the order. Two things do not change the price: which compound is in the vial and how many milligrams the label claims. Every single-active peptide vial bills at the same rate.

What drives the cost of a test

A peptide test is priced per vial because most of the work is per vial. Four things set the cost.

• The reference standard. Identity and content are measured against a certified reference standard of the same compound (a characterized reference material where no certified standard exists). The lab has to buy that standard and verify its method for every compound it reports. That is why a compound outside our panel needs advance notice. The lead time is on the pricing page.
• Bench and instrument time. Every vial is photographed at intake, prepared by weight, run on the HPLC, and reviewed by an analyst, who seals its certificate. Ten vials are ten samples. Our instrument and method are listed on lab facts.
• How many results are reported. A purity percentage alone is the least work. Confirming identity and measuring the milligrams in the vial both need the reference standard, so a full panel is more work than a purity-only test, and it tells you more.
• How many actives are in the vial. A blend needs a standard for each active and a method that separates them.

Two more things move your total: how many vials are on the order and how fast you need the results.

What the price includes

• Identity — retention time + UV character against the reference standard. The pass/fail question.
• Chromatographic purity (area %) — how much of the peptide material is the intended peptide vs related impurities.
• Net-peptide assay (mg/vial) — the actual milligrams in the vial, measured, not assumed from the label. The number purity alone can't give you.
• Chain of custody — your vial photographed at intake, the photo printed on the certificate.
• A verifiable certificate — sealed with a SHA-256 fingerprint any stranger can check at /verify, so it can't be quietly edited or reused.
• Appearance and a conformity check — appearance is reported on every certificate, and every certificate carries a Conforms or Does not conform line against the specifications printed on it. Give us a target spec and we assess against that.
• Your lot number — enter a batch or lot number on the order form and it prints on that vial's certificate.
• Standard turnaround — typically 5–7 business days from receipt, 7 business days maximum.
• Delivery — each certificate is emailed as a sealed PDF when it is issued, so finished results are not held for the last vial.

One price covers all of it. There is no separate fee for the certificate, the photo or the verification page. The steps are laid out in how third-party testing works.

What the price does not include

• Shipping to the lab. You pay the carrier. Any carrier works and no signature is needed. Packing steps are on the submission page.
• The vial itself. Testing uses up the sample, so nothing is sent back. Count the vial as part of the cost.
• Solution pH. A paid add-on listed on the pricing page. It is not part of the online total, so note it on your order and we invoice it separately.
• A later re-test. A certificate reports on the one vial we tested. New or replacement material sent afterwards, from the same lot or a different one, is a new order at the current rates.
• Bacterial endotoxin. A $150 per-vial add-on (USP <85>, kinetic chromogenic LAL, run in-house), flat — outside the volume tiers and the rush surcharge — ticked per vial on the order form and reported on its own certificate. For now it needs a second unopened vial of the same lot; liquids such as bacteriostatic water are tested from the same vial. It is not a sterility test.
• Tests outside our scope. We run RP-HPLC-UV. Sterility and heavy metals testing are not offered here, so no price on this page covers them. See the scope of services.

How order size changes the rate

The tier that wins applies to every vial on the order — 1–4 vials at $150, 5–9 at $125, 10+ at $100. The vials can be different compounds.

Check the next size up before you order. An order of 4 vials costs $600 and an order of 5 costs $625, so the extra vial adds only $25. An order of 9 vials costs $1,125 and an order of 10 costs $1,000, so the extra vial lowers the bill by $125.

Quirk worth knowing: a $75 bacteriostatic water counts toward the tier. On their own, 4 peptide vials cost $600. Add a bacteriostatic water and the order is $575, with the extra test included. More in the bacteriostatic water testing guide.

How blends are priced

Each extra active in one vial adds +50% to that vial. At the $150 rate a two-active vial is $225, three actives $300, four $375. The surcharge follows your tier, so on an order of 5–9 vials a two-active vial is $187.50.

A blend still counts as one vial toward the volume rates. Every active gets its own identity, purity, and content row on one certificate, because a blend where one component is missing is precisely the thing worth catching.

Two cautions. Not every combination can be separated cleanly, so send us the list of actives before you ship and we will confirm what we can quantify. And if a vial turns out to hold more actives than the order says, it is re-priced at the blend rate and waits until the difference is paid.

Rush and faster service

Standard turnaround is included in the price. Faster service is a surcharge on the order total, because expediting moves every vial on the order ahead of other work.

Turnaround is counted from the day the lab logs your vials in. Shipping time is separate. Rush batches above 4 vials and same-day service depend on capacity, so ask before you ship.

Worked examples

These totals come from the same pricing rules the order form bills with. Vials hold one active and run at standard turnaround unless the row says otherwise.

Tier rate is the per-vial rate the order qualifies for. Rush adds +100% to the order total. A two-active vial bills at the tier rate +50%.

Cost per vial for a group

The volume rates count the vials on one order, not who owns them. A group that puts its vials on one order pays the lower rate on every vial.

A group of 5 with one vial each pays $625 on one order, or $125 per person. A group of 10 with one vial each pays $1,000 on one order, or $100 per person. Ordering alone, each person would pay $150.

Split the bill by vial, not evenly. Single-active vials all cost the same, but a blend costs more. On an order of 10 vials, each single-active vial is $100 and a two-active vial is $150.

One order means one name, one email address and one invoice. Every certificate on the order carries the name entered on the order form, and results go to that one email address. The full walk-through is on the group testing page.

The cheap-testing checklist

When a price looks dramatically lower, one of these is usually missing — ask directly:

1. Is identity confirmed against a reference standard, or is it purity-only?
2. Is content reported in mg per vial, or does the label's claim just get repeated?
3. Is my actual vial photographed and printed on the certificate?
4. Can anyone verify the certificate independently, or is it just a PDF?
5. Is the lab independent, or connected to a vendor?

Get your exact total

Live prices are always on the pricing page, and the order form shows your exact total — tiers, blends, rush — before you pay a cent. Submitting the form gives you a secure Square payment link on screen, and an itemized bill with the same link by email. Nothing is charged until you pay it, and testing does not begin until the order is paid in full. The turnaround clock starts the day the lab logs your vials in.
