Retatrutide, and best sellers
The full Retatrutide range first, 20mg through 40mg. Everything after it is ranked by units actually sold, and Shopify recalculates that order.
What every vial carries
≥99% purity
HPLC verified per lot.
Third party COA
Independent certificate of analysis.
Ships from Canada
Victoria BC to all 13 provinces and territories.
Lot traceability
Batch number on every vial.
How an order works
No account required, no minimum, no waiting on a quote.
Every lot is assayed
An independent laboratory runs HPLC with mass spectrometry on the lot before it is released. Lots below 99% are not published.
Certificate on request
Every vial's lot number is matched to a lot-specific certificate, available on request. Where the assay data is on file, purity, identity, net peptide content, lot number and method are printed on the product page.
Tracked, not refrigerated
Sent from Victoria, British Columbia by tracked courier. Lyophilized material is ambient stable for a domestic shipment, so parcels are not shipped refrigerated.
Canada only, no border
We ship to all 13 provinces and territories. Nothing clears customs, so nothing sits at the border.
Laboratory handling
Storing it correctly
What arrives, how to keep it, and what is actually in the vial.
Before reconstitution
Lyophilized vials arrive as a fine white powder or cake. Store sealed at 2 to 8 degrees C for short term reference, or at minus 20 degrees C for extended stability. Keep away from light and moisture until you are ready to reconstitute.
Reconstituted form
Once reconstituted with bacteriostatic or sterile water, peptides are typically stored at 2 to 8 degrees C and used within the working window described in the associated research literature for that molecule. Avoid repeated warm up and cool down cycles.
Handling hazards
Treat every compound as a potential irritant and sensitizer. Work in a ventilated area, wear gloves and eye protection, and avoid generating airborne dust when handling lyophilized powder. Many sequences are hygroscopic, so keep vials sealed until you are ready to reconstitute.

Before you order
Questions, answered
What is a peptide?
Peptides are short chains of amino acids, the same building blocks that make proteins. They are used in laboratory research to study cell signalling, metabolism, tissue repair and hormone pathways. They are not foods, supplements or medicines.
What is retatrutide?
Retatrutide is a research peptide that activates GLP-1, GIP and glucagon receptors. It has been studied in clinical trials for metabolic effects, but the material sold here is a research reagent only. It is not a drug, not for human use, and not equivalent to any approved medication.
Is this sold for human use?
No. Everything in this catalogue is supplied strictly for in-vitro laboratory research. It is not a drug, it is not approved by Health Canada or the FDA for human use, and it is not intended to diagnose, treat, cure or prevent any disease.
Do I have to be a certain age to order?
Yes. Purchasers must be 19 or older, which is the age of majority in British Columbia.
Can I see the certificate of analysis?
Yes. Every vial's lot number is printed on the label and matched to a lot-specific HPLC and mass spectrometry certificate. The key figures are published on the product page where the lot record is on file, and the full signed certificate is available on request.
Does it need to be shipped refrigerated?
No. Lyophilized peptides are stable at ambient temperature for the length of a domestic shipment, so parcels are not shipped refrigerated.
Where do you ship, and how long does it take?
Within Canada only, to all 13 provinces and territories, dispatched from Victoria, British Columbia. Standard delivery is 5 to 8 business days and Express is 1 to 2, counted from dispatch. Remote and northern destinations can take longer.
How much is shipping?
Standard is $12.95 CAD and is free on orders of $150.00 CAD and over. Express is $20.00 CAD. Your rate is shown at checkout before payment.
What if a vial arrives damaged?
Photograph the shipment before touching the contents and email us within 48 hours of delivery. Once we confirm the damage we reship the affected items at no cost.
Can I return a vial I have opened?
No. Once a tamper seal is broken or a peptide has been reconstituted the product is considered used and cannot be returned, exchanged or refunded. Unopened orders can be cancelled free until they enter the packing queue, typically within 2 hours of checkout.
