(made to order)How ordering works
Open a trade account
Free, in a couple of minutes. Prices are shown to everyone; an account is what lets you order. Who qualifies.
Build the order
Whole sealed boxes, from $100 of goods on a first order, stepping up with the account to $1,000 by the fourth. Freight included to US addresses from $1,000 of goods. The rules, with examples.
Pay the proforma
By credit card on the secure card page, by Wise or Interac e-Transfer (from Canada) with the 4-digit code on it, or in Bitcoin or USDT to the address on it, to the exact figure. A card payment confirms itself within minutes, a coin payment on the chain. Sending the exact amount.
Track it to the door
Dispatch in 1 to 2 business days for lines on the shelf, tracked to a US address or, through the desk, abroad. How it ships.
Released against a written specification
Every batch is supplied to a written specification. For a peptide line its certificate reports purity by RP-HPLC, net content and identity by mass spectrometry; a protein, solution or supply line reports the results its own page lists. The retest date is on the batch record. How a batch is made and released, and how to verify a certificate.
Verify a batch, and what volume earns
Verify a batch number
The same number is on the vial, the carton, the packing list and the certificate: L2607-RT30-0002 reads as lyophilised, July 2026, RT30, second batch. Type any of them in to see the record the certificate was issued from.
Volume pricing, two ways
A large order earns its own discount: 5% from $5,000, 10% from $10,000, 15% from $20,000, 20% from $50,000 of goods in one order. A regular account earns a tier on lifetime paid spend, off every later order: 3% from $5,000, 6% from $15,000, 10% from $50,000, 15% from $100,000. The better of the two applies at checkout, never both, and there is no code to enter.

Notes on price: the cheapest lines, what a price covers, buying in bulk
The cheapest research peptides on this list, online in the USA
Two different questions, so two different answers. Leaving out bacteriostatic water, the cheapest box sold singly is NAD+ 100mg x 10 vials (NJ100) at $22.60 for a sealed box of ten. The cheapest milligram is Glutathione 1500mg x 10 vials (GTT), which works out at $0.00359 per mg. Those are the cheapest lines here, computed from the list as it stands today, and not a claim about anyone else’s.
To put a quote from somewhere else on the same scale, the price per mg calculator takes a strength, a vial count and a box price and gives the only figure the two have in common. The whole list, sorted, is on the price list.
Cheap research peptides for sale: what the price has to cover
A box price has to pay for the peptide and then for everything around it: the vial, the stopper, the fill, the label, the carton, the release testing, the certificate that goes with the batch, cold storage, and the freight. Those costs barely move with the strength in the vial, which is why a bigger vial is almost always cheaper per milligram and why per box is a poor way to compare.
When a price sits well under what those cover, something in the list has usually gone. The things worth asking for by name: a certificate tied to the batch number on the box rather than a specimen from another lot; a release specification with actual limits on it; a retest date; a net content within the labelled amount; and a sealed box rather than loose vials. Every line here ships as a sealed box (ten vials, fourteen for L-Carnitine) with the batch number on it, the certificate for that batch is on file, and each compound’s page prints the specification it is released against: fixed limits for the peptide, small-molecule and solution lines, and for the protein and preparation lines the methods, with the limit on the batch certificate. Any number can be checked on the certificate page.
Where to buy research peptides cheap, in bulk, online
Here, on account, by the sealed box. The unit of sale is one box of ten vials of a single strength, the order minimum runs from $100 of goods on a first order, stepping up with the account to $1,000 by the fourth, and freight to a US address is included from $1,000 of goods. The price falls two ways: an order of $5,000 of goods or more takes 5 percent off on the spot, rising to 20 percent at $50,000, and lifetime spend moves an account up a tier that comes off every later order. The better of the two applies.

Purity 98 or 99 percent: what the number on a peptide certificate does and does not tell you
98 or 99 percent is the main peak’s share of the HPLC peak area at 220 nm, not of the vial’s weight: a 10mg vial at 99 percent holds 10mg of material.

Questions buyers ask first
Ask the trade deskIs International Peptides a real company?
International Peptides (intlpeptides.com) sells research peptides to trade accounts by the sealed box of ten vials, priced in US dollars and paid against a proforma by credit card, Wise, Interac e-Transfer (from Canada), Bitcoin or USDT. It is one storefront of a wholesale supplier that ships from stock held in the United States; its trade desk is reached on +1 646-847-1895 or orders@
What if my order does not arrive, or arrives wrong?
A parcel to a US address is at our risk until it is delivered to you (clause 4 of the terms of sale, DAP, delivered in the United States), so one lost in transit is not yours to carry: tell the desk; for an order abroad, ask the desk before you pay where the risk passes. A shortage, transit damage or a wrong item is reported within five business days of delivery, with photographs of the carton and the vials, and the freight claim is ours to handle; a batch that fails its specification is withdrawn and the order replaced or credited. The rule in full is clause 6; the claims page sets out every case.
How can I pay?
Against a proforma invoice fixed in US dollars: by credit card, by Wise, by Interac e-Transfer from Canada (in Canadian dollars), or in Bitcoin or USDT. PayPal is not taken. A card is paid on a secure card page, charged in US dollars to a US delivery address and in Canadian dollars to any other, at the figure the card page shows before you pay, and the order moves on by itself a few minutes later. A Wise or e-Transfer payment carries the 4-digit code on the proforma and is matched by it; a coin payment settles the order on any day once it confirms on the chain: in minutes for USDT, usually within the hour for Bitcoin. A transfer or a coin payment cannot be pulled back once sent, so the protections are written into the terms of sale instead: if we cannot fulfil an order, it is cancelled and repaid in full by the same route the money came (clause 5); a parcel to a US address is at our risk until it is delivered (clause 4); and the proforma shows the goods, the freight, the total and the address before you pay. A first order can be as small as $100. Paying in Bitcoin or USDT.
What are wholesale peptides?
The same research compounds sold by the sealed box rather than the single vial, at trade prices, to businesses buying to resell or for laboratory research. Here that means boxes of ten vials of one strength, priced per box, per vial and per milligram, against an order minimum that starts at $100 of goods. Wholesale changes the unit of sale and the price, not the material.
How do I buy wholesale peptides?
Open a free trade account, which takes a few minutes and needs a business, or a person trading in their own name, that resells the goods or uses them for laboratory research; build the order from the public price list; and pay the proforma by credit card, Wise, Interac e-Transfer (from Canada), Bitcoin or USDT. Prices are shown to everyone without an account, so you can price the order before you register. The whole process.
What does the site sell?
81 compounds in 168 vial strengths, bacteriostatic water and vitamin B12 among them, from $5.19 to $436.00 per box of ten sealed vials, fourteen for L-Carnitine. Every line is on the price list with its code, strength, box price and price per vial.
Who can order?
Trade accounts, in the United States and abroad: distributors and resellers, research laboratories and universities, and people trading in their own name for resale or laboratory research; not individuals buying for their own use. Prices are public; an account, free and opened in a few minutes, is what lets you order.
Do you ship to Canada and other countries?
Yes. Orders ship from stock held in the United States to Canada, the United Kingdom, the European Union, Australia and most other countries. Online checkout takes a US delivery address. For anywhere else, open a free trade account, then email the desk your basket from the order page, or write from the contact page with the account name, codes, quantities and delivery address. The desk places the order, to the same minimums, and puts the freight on the proforma before you pay; the steps are on the shipping page.
What is the minimum order?
It steps up with the account: $100 on a first order, $300 on the second, $500 on the third and $1,000 from the fourth order on, counted on goods and on the orders the account has already paid for. One sealed box of ten vials is the smallest quantity of a regular line, and a line marked special order has a 50-box minimum. BAC3 and BAC10 are sold 10 boxes at a time: bacteriostatic water ships in its own parcel. Boxes are not split. The rules, with examples.
How is an order paid?
Against a proforma invoice. By credit card, on the secure card page the order opens; by Wise or Interac e-Transfer (from Canada), with only the 4-digit code on the proforma as the note; or in Bitcoin or USDT to the address on the proforma, where the exact figure is what matches the payment and it confirms itself on the chain. Whichever way, the order moves to packing once the payment lands. How to send the exact amount.
How quickly does it ship?
Lines on the shelf leave in 1 to 2 business days after cleared payment and are normally delivered 1 to 3 business days later in the United States, tracked and plainly packed. To a US address, freight is included from $1,000 of goods and quoted at checkout below that. To Canada and other countries the desk puts the freight and the transit time on the proforma. Lines marked ships in 1 week or ships in 2 weeks are on their way in, lines marked made to order leave in about four weeks, and lines marked special order are brought in on a 50-box minimum rather than held in stock. Today’s shelf shows which is which.
Is there a certificate of analysis?
Yes. Every batch has a certificate of analysis, sent with the shipment, and again on request. For a peptide line it reports purity by RP-HPLC at not less than 98 percent, net content against the label and identity by mass spectrometry, with the chromatogram and the spectrum; a protein, solution or supply line reports the results its own page lists. Any batch number can be checked against the register its certificate was issued from.
Is any of this for human use?
No. Everything on the site is a research chemical for laboratory use in vitro, sold to trade accounts, and is not for human or animal consumption.
