Frequently asked questions

Peptuvia is a research peptide marketplace. Instead of being one vendor with one price list, we list multiple vetted independent sources for each compound so you can compare them on price, shipping origin, and published lab results — then buy from whichever one you prefer. We work with independent US analytical labs to test batches, and every result we get is published publicly, pass or fail.

Two differences. First, we're a marketplace, not a reseller: you see several sources per compound with their prices side by side, rather than a single marked-up price. Second, the quality data is independent — results come from analytical labs we work with directly and get published whether they pass or fail, instead of a certificate the vendor picked out to show you.

Most US peptide brands buy from the same class of overseas manufacturers we do, then resell at roughly 10–12× that price. You're paying for a domestic middleman, not a different molecule. Buying through the marketplace removes that layer: you pay close to source pricing plus our marketplace margin.

No. Peptuvia never manufactures, takes title to, or physically handles inventory. Orders are fulfilled and shipped by the independent sources — many of them from their own regional warehouses in the US, UK, EU (Germany), Australia, and Canada. We handle the storefront, the order, the payment, the lab relationships, and support.

No. Checkout works as a guest — you only need an email address and a shipping address. Creating an account is optional and just adds order history and a saved shipping address. Either way you can look up any order with its order number and the email you used at checkout.

Check the receipts rather than taking our word for it. Every lab result we hold is published in a public COA library with the batch code, the testing lab, and the date — failures included. Several of our sources also carry independently published track records on third-party databases like Finnrick and Janoshik, which we don't control. And every order ships with tracking you can follow from dispatch to delivery.

A COA is the lab document that says what is actually in a specific production batch. A useful one reports four things: the identity of the compound, its purity as a percentage, the batch or lot code it applies to, and the date and name of the lab that ran the analysis. Without a batch code tying it to the vial in your hand, a COA is marketing, not evidence.

Check four things in order. Identity: mass spectrometry should confirm the molecular weight matches the target peptide. Purity: the HPLC figure, where 98% or higher is a pass. Batch / lot code: it must match the code on your vial — that's the link between the paper and the product. Test date and lab: recent, and from a named independent facility rather than the manufacturer's own QC.

They answer different questions. HPLC (High-Performance Liquid Chromatography) separates the sample and measures how much of it is the target peptide versus impurities — that's where the purity percentage comes from. Mass spectrometry measures molecular weight to confirm the compound is the peptide it claims to be. A 99% purity number means nothing if the identity is wrong, which is why a credible COA carries both.

It's the HPLC peak area for the target compound relative to everything else detected in the sample. We treat 98% or higher as a pass, and hold sources to 99% or better — anything under that is a refund or reship on the source's dime.

Purity tells you what fraction of the powder is the target peptide; net content tells you how many milligrams of it are actually in the vial. A vial can be 99% pure and still be under-filled against its label. Where the lab measures it, we publish net peptide content in mg alongside the labeled amount, so you can see whether a batch is short, on-label, or over-label.

Enter the batch code on the verification page. You'll get that batch's independent results — purity, identity, net content where measured, the lab, and the date — plus the COA itself where a PDF is available. Every batch page has a permanent URL at https://peptuvia.com/verify/<batch-code>, so it stays citable and shareable.

It's printed on the vial or kit label from the source. You can also find published batch codes in the test history on each product page and in the COA library, which lists every verified batch we hold.

No. Results come to us directly from the independent lab, not from the vendor, and customers can't upload their own certificates. We publish everything we receive — passes and failures — so no source can surface only its best batch. The complete history for a compound sits on its product page.

Batch-specific. Each published result ties to an actual production run, identified by its batch code. That's deliberately different from the industry-standard stock COA — a certificate from a sample sent off months ago, used to market every batch since.

It gets published anyway, flagged for review rather than quietly dropped, and it counts against that product's quality score. For your order, a failure is covered: if an independent test of your batch comes back under 99% purity, we reship it free or refund the order — your choice.

Each product carries a grade derived from the average purity of every published independent test for it: A+ is above 99.5%, A is above 99%, B is 97–99%, C is 95–97%, and D is under 95%. Alongside the grade you'll see the number of tests, the pass rate, and the range from lowest to highest result, so a single flattering test can't carry the score.

Independent US analytical facilities we work with directly — the network is listed on our testing page, sorted to show the one nearest your state first. Bioviridian is an established partner today and we're actively onboarding more labs to widen coverage. We also work with independent labs outside the US as that network expands.

HPLC purity and mass-spec identity are the standard panel. Endotoxin (LAL) and heavy-metal (ICP-MS) screening are available as add-ons at several of our partner labs for research applications that need sterility or elemental-impurity data. Where those were run, the result appears on the batch's verification page.

Not yet. The COA library grows as results come in from the labs, so a specific batch may be verified before others from the same source. The honest way to check is the product page: it shows the full test history for that compound, and the COA library shows every verified batch we hold across the catalog.

Nothing stops you, and we'd encourage it — send a vial to any independent analytical lab and compare their number to ours. Routing an order through a partner lab as a checkout add-on is paused right now, so orders ship direct while we publish batch results from the labs we work with. If you have a specific testing need, email us and we'll point you at a facility.

Find the compound in the catalog, pick a source from the list on the product page — they're compared on price, shipping origin, and published purity — add it to your cart, then check out with your shipping address and payment method. You'll get an email confirmation once payment is detected.

Cash and bank apps through a hosted checkout — Zelle, Venmo, Cash App, Wise, Revolut and N26 — plus card, Apple Pay and Google Pay through a payment partner, and self-custodial crypto (USDC, USDT, ETH, SOL). Gift cards and store credit can be applied to any order. The exact list live at any moment is shown on the checkout page.

No. Plenty of orders are paid with Zelle, Venmo, Cash App or Wise, and no wallet is involved. Crypto is offered because it's fast, cheap and self-custodial, not because it's required.

Paying by cash app or card routes through a third-party provider that charges its own fee, and that fee is shown before you confirm — it's never added silently after the fact. Paying in crypto has no provider fee; you only pay the network's own transaction cost.

Crypto payments are self-custodial: you send from your own wallet or exchange to the address shown, and we detect the payment on-chain. If you pay by card, the payment partner handles it on their own hosted page — we never see or store card numbers, and there's no KYC with us.

As soon as your payment is detected, automatically — you'll get a confirmation email with your order number. An order that's never paid is cancelled automatically after 48 hours, so nothing sits pending indefinitely. If you started a payment and something went wrong, reply to the confirmation email or contact support and we'll sort it out.

Get in touch immediately with your order number. Before an order is forwarded to the source we can usually change the address or cancel it. Once the source has dispatched it, we can't recall or modify the parcel.

Yes, and the live ones are all listed publicly on our deals page — if a code isn't there, it isn't valid. One code per order, applied to the product subtotal (never to shipping or lab testing).

Yes. Gift codes start with GIFT- and apply to your whole order total, including shipping and any testing fee. If the card is worth more than the order, the remainder stays on it for next time. You can check any card's remaining balance at any point.

Enter your order number and the email you used at checkout on the tracking page, and you'll see live status — payment, dispatch, tracking number, and any published test results for your batch. Tracking numbers are also emailed as soon as the source provides them.

Out-of-stock offers show a "Notify me" option on the product page. Leave your email and you'll get a message the moment that source restocks. Often another source in the same list has it in stock right now, so it's worth checking the alternatives before waiting.

Email us with the compounds and quantities you need and we'll check pricing and lead times with the sources directly. Larger orders often route differently than a standard cart, so it's worth asking first.

It depends on the source you pick. Many ship from in-region warehouses in the US, UK, EU (Germany), Australia, or Canada, so the parcel is a domestic delivery with no customs leg. Others ship direct from the manufacturer. Each product page shows the origin for every source, and you can filter the list by region.

Sources shipping from an in-region warehouse typically deliver in about 2–7 days. Sources shipping direct from the manufacturer usually take 12–21 days. The estimate for the specific source you've chosen is shown on the product page and again at checkout.

It's set per source, because each one ships its own parcel from its own location. Rates start around $15–$20 flat from a regional warehouse, and many sources waive shipping once their own product subtotal passes a free-shipping threshold — commonly $800, though it varies by source. You'll see the exact figure for each source in your cart before you pay.

Because your cart included products from more than one source, and each ships its own parcel with its own shipping fee and its own timeline. If you'd rather have one parcel and one shipping charge, consolidate the cart onto a single source — the cart flags this when it applies.

Coverage varies by source, since each sets its own export restrictions. The country checker lists exactly which vendors deliver to your country, and checkout blocks any source in your cart that can't ship to your address before you pay.

Orders from an in-region warehouse are domestic deliveries and never cross a border. For parcels that do ship internationally, we cover the risk: if one is held in customs, we reship it or refund the order.

Yes. Parcels ship in plain packaging with no product names or branding on the outside. Every order is tracked, and there's no minimum order size to get tracked delivery.

Most listings are kits containing multiple vials of lyophilized (freeze-dried) powder. Each product page shows the milligrams per vial, the number of vials in the kit, and the price both per vial and per kit, so you can compare against vendors that quote single vials.

That's the marketplace part. The same molecule is available from more than one vetted source, each with its own price, shipping origin, delivery time, and published purity history. Rather than picking for you, we list them side by side so you can weigh cost against speed and track record.

Lyophilized vials are stable stored cold, dark, and dry — a fridge or freezer, away from light — and are far more sensitive once reconstituted. Handling and storage specifics are covered in the storage guide rather than summarized here, because the details matter.

No. Everything sold here is a research chemical for in-vitro laboratory study, and we don't publish dosing, protocols, or anything that could be read as medical guidance. Our content covers analytical quality, verification, storage, and the underlying science.

They're the same molecules, generally made by the same class of manufacturers that supply US resellers. The difference is what you pay and what you can verify: our purity and identity data is published per batch and traceable to a batch code, rather than asserted on a label.

If an independent lab test of your batch comes back under 99% purity, we reship it free or refund the order — your choice. That's the same standard we hold sources to, which is why it's a commitment rather than a marketing line.

Because these are research chemicals, delivered goods can't be returned once they're out of our hands — with one exception: a documented quality failure. If a batch fails on purity or identity, we arrange a replacement or a full refund.

Tracking can sit quiet for a few days between scans, especially on an international leg. If it's been longer than the estimate you were quoted, or the tracking hasn't moved in several days, contact support with your order number and we'll chase the source and the carrier directly.

Email support with your order number and photos of what arrived, including the packaging. We take it up with the source and arrange a replacement or refund — you don't have to negotiate with the vendor yourself.

Use the support form or email hello@peptuvia.com. Order questions get routed straight to the team handling your shipment, so include your order number if you have one. We reply by email.

No. Everything sold here is a research chemical intended for in-vitro laboratory study only. These products are not drugs, supplements, foods, or medical devices, and are not for human or veterinary use. Nothing on this site is medical advice.

No. Nothing on this site has been evaluated by the U.S. Food and Drug Administration, and no product is intended to diagnose, treat, cure, or prevent any disease. Peptuvia is a chemical supplier — not a compounding pharmacy under section 503A, and not an outsourcing facility under section 503B.

You must be at least 18 and legally permitted to purchase research chemicals where you live.

That depends on your jurisdiction, and it's your responsibility to check — we can't give legal advice. What we can tell you is that sources set their own export restrictions, so checkout will block any source that can't legally ship to your country.

We collect what's needed to fulfil and support your order — email, shipping address, order history — and pass the shipping details to the source that's actually sending your parcel. We never see or store card numbers. The privacy policy covers what's kept and for how long.

Yes, and it's self-serve — sign up and get a personal code instantly, with no follower minimum. Your audience gets 15% off, and you earn 10% commission on every order they place, rising to 20% once you pass 50 confirmed orders. Commissions are recurring on reorders, with payouts in USDC or SOL on Solana, or as store credit if you'd rather skip crypto.

Yes. After a delivery is confirmed we email you a review link for that order, so reviews are tied to real purchases rather than open to anyone. Ratings are published per source on the product pages, which is what makes them useful when you're choosing between vendors.
