About Deer
A small Canadian supplier that shows its work.
Deer Supply & Research makes GLP weight-loss medications and recovery peptides in Canada and ships them across the country. No storefront theatre, no miracle promises. Just a catalog, consistent quality behind it, and a team that answers email.
Who we are
Deer exists because getting reliable, tested peptides in Canada was harder than it should be. We keep the catalog small, test what we sell, and stay reachable at every step of your order.
Questions? Talk to us →01 · Who we are
Made in Canada, plainly said
We are a Canadian team focused on one thing: making research peptides people can actually verify. Everything we sell is made in Canada with a focus on purity, quality, and safety, priced fairly, and shipped discreetly to every province.
We write the way we talk. When trial results are cited on this site, they are the published averages, always with the same caveat: trial averages are not a prediction of your result. When we do not know something, we say so. And when a package question or an order problem comes up, a real person at info@deer.supply sorts it out.
02 · How we test
Independent labs, batch by batch
Third party
Labs we do not own
Batches are sent to independent analytical labs for testing. We do not test our own products in-house and grade our own homework.
COA
A report you can open
Tested batches carry a certificate of analysis with the purity result and batch identifier. The COA links on product pages go to the actual documents.
By request
Ask for any batch
If a batch report is not posted yet, email lab@deer.supply and we will send the results for the batch in your order.
03 · The fine print, in plain words
What we are, and what we are not
Deer sells research supplies for personal research purposes. Our products are not approved by Health Canada, do not carry a DIN, and are not pharmacy-dispensed prescription medications. Nothing on this site is medical advice, and nothing here is a promise about your result.
What we can promise is the part we control: what is in the vial, verified by an independent lab, at a fair price, delivered discreetly. For the full legal wording, read the disclaimer. For decisions about your health, talk to a licensed healthcare professional.
