Canadian research peptides · independently tested
Canada’s most documented peptide source — 244 independent lab reports, a published purity floor of 93.844%, and domestic shipping.
Overseas orders can be delayed, held, or seized at customs. A Canadian vendor shipping domestically removes that risk entirely and gets your order to you faster. This single choice eliminates the most common practical headache. (More on the legal status: are peptides legal in Canada?)
No regulator checks what's in these vials, so testing is your only quality signal — and not all "testing" counts. Require:
Don't marry one vendor. Keep two or three that ship domestically and pass the testing checks, and buy from whoever has what you need in stock. See buying peptides in Canada for the longer version.

Most bad outcomes in this category come from doing the steps in the wrong order: choosing a product, then a price, then a vendor, then discovering the testing question. Reverse it. Choose the vendor first, on testing and shipping origin; then the product, on whether its current batch has a report; then the price, which by that point is a comparison between two known quantities rather than a known one and a guess. The order costs nothing and removes the failure mode where a good price on an untested vial decides the purchase.
Resolve one report. Take a report number from the vendor's listing to the laboratory's own site and confirm the record comes back naming the vendor. Confirm the origin. Ask where the parcel ships from and, if the vendor claims a Canadian origin, look for a review that mentions domestic tracking rather than an international arrival scan. Read the non-arrival policy. The sentence that says what happens if a parcel is lost, held or refused is the most important sentence on the site. Check the coupon field, not the banner. If you are using a code, watch the discount line appear at the cart before entering payment details; a discount that only appears on a banner has not applied.
Card payment through a processor offers chargeback recourse; e-transfer and crypto do not. Both of the latter are common in this category because processors are reluctant, and their presence is not a red flag in itself. What matters is the sequence: a vendor that offers a card option and then, after you have chosen it, steers you to an irreversible one has changed the deal. Pay by the method you chose, or do not pay.
Photograph the label with its batch number before discarding anything, and match that batch to the report. If the batch on the label is newer than the newest report, the honest status of your vial is untested so far; note the batch and check the vendor's archive again in a few weeks, because testing lags production. Store lyophilised product cold, dark and dry. A report describes the vial at the laboratory; the buyer's storage decides what it is a month later.
These products are sold in Canada as research materials, not as approved drugs or supplements, and the label saying so is a statement about regulatory category rather than about quality. Buyers should read the current Health Canada guidance on personal importation before ordering from outside the country, and should understand that the domestic-vendor path exists precisely because the border is where imported parcels in this category most often stop. Nothing on this page is medical or legal advice.

Testing: 244 Janoshik reports across 133 products, 99.03% mean purity over the 181 that state a figure, 93.844% to 99.99%, each hosted on the testing lab's domain. Shipping: from inside Canada, in Canadian dollars, with no customs step for a Canadian buyer. Time: the vendor has been answering publicly in its own forum threads since November 2021. All of it, itemised.
