Vancouver Island Peptides is British Columbia's leading source for domestic peptides in Canada — research-grade compounds synthesized here, not imported overseas. Every compound we offer is produced at our boutique Vancouver lab partner — not mass-produced, not rebranded imports. When you buy peptides in Canada through us, you are getting West Coast quality with full traceability.
Retatrutide is a next-generation triple agonist peptide targeting the GLP-1, GIP, and glucagon receptors simultaneously. It is one of the most researched metabolic compounds in the world, with clinical studies showing significant weight reduction and metabolic improvement. We offer Retatrutide Canada in both 10mg and 20mg vials, synthesized domestically in Vancouver, BC. Unlike imported alternatives, our Retatrutide is produced locally — no overseas seizure risk, no unknown purity.

The landscape of GLP-1 research peptides is rapidly evolving. While Ozempic (Semaglutide) targets only the GLP-1 receptor and Tirzepatide targets both GLP-1 and GIP, Retatrutide is a novel triple agonist — it targets GLP-1, GIP, and Glucagon receptors simultaneously, making it the most advanced compound in its class for metabolic research applications.
All products are sold strictly for laboratory research purposes only and are not intended for human consumption.
Tirzepatide is a dual GLP-1/GIP receptor agonist widely studied for metabolic health and weight management. Our Tirzepatide Canada offering is available in 10mg and 20mg vials, synthesized at our Vancouver lab partner to research-grade standards.
Our recovery lineup includes BPC-157 Canada, TB-500 Canada, KPV, GHK-Cu, and MOTS-C — all synthesized domestically in British Columbia. These compounds are widely studied for tissue repair, gut health, inflammation reduction, and mitochondrial support. All are available as true domestic peptides Canada — BC-synthesized, not sourced overseas and rebranded.
We are a small, BC-based operation with a single focus: delivering the highest purity research peptides in Canada at fair prices. No middlemen. No imported compounds. No compromises. Pacific Northwest Purity is not just our tagline — it is our standard for every vial we produce.
Shakepay is the easiest way for Canadians to buy and send Bitcoin. Here's how to get set up:
Shakepay is a Canadian-regulated platform. Your funds and identity are protected under Canadian financial regulations.
Your Transaction ID (TXID) is a unique code that proves your Bitcoin payment was sent. Here's how to find it on common platforms:
Once you have your TXID, simply reply to your order confirmation email with it and we will verify your payment on the blockchain.
TXIDs are 64-character strings of letters and numbers. They look like: a1b2c3d4e5f6...
All products are sold as Full Kits (10 vials). We moved to full-kit-only to simplify ordering and ensure customers receive a complete supply for their protocol.
Each order is limited to one Full Kit per product to maintain fair availability across our customer base. If you require larger quantities, contact us at orders@vancouverislandpeptides.com.
All products are synthesized in small batches at our Vancouver lab partner. Kit limits ensure we can serve all customers consistently.
Our products are research-grade compounds synthesized at our boutique Vancouver lab partner to the highest purity standards. However, there are important things to know before ordering:
Pacific Northwest Purity is not just our tagline — it is our commitment to every compound we offer.
Here is what to expect after your payment is verified on the blockchain:

Vancouver Island Peptides offers Retatrutide Canada in 10mg and 20mg vials, synthesized domestically at our Vancouver, BC lab partner. Unlike many suppliers who import from overseas, our Retatrutide is produced right here in British Columbia — ensuring consistent purity, no import risk, and full traceability.
Retatrutide is a triple agonist peptide targeting GLP-1, GIP, and glucagon receptors simultaneously. It is one of the most studied metabolic compounds available for research purposes.
All products are for research and personal wellness purposes only. Not approved by Health Canada. Consult a healthcare provider before use.
Retatrutide (also referred to as LY3437943) is a next-generation synthetic peptide and triple agonist that simultaneously activates three hormone receptors:
This triple-receptor mechanism is what distinguishes Retatrutide from single-agonist peptides like semaglutide, or dual-agonists like Tirzepatide. Early clinical research has shown exceptional results in metabolic optimization and weight management.
Retatrutide is currently under clinical investigation and is not approved by Health Canada or the FDA for human use. Our product is for research purposes only.
Both are GLP-1 based peptides, but they differ significantly in mechanism and potency:
For researchers comparing the two, Retatrutide's triple mechanism offers broader metabolic coverage, while Tirzepatide is a well-established dual-agonist with a longer research history.
Both products are for research purposes only. Not for human consumption.
Yes. All our Canadian peptides are stocked and shipped directly from our Canadian warehouse. You will not have to deal with international customs, border seizures, or extended delivery times. Every order ships from within Canada, typically within 1-2 business days of payment confirmation.
We ship Canada-wide. No international orders are accepted at this time.
Retatrutide should be reconstituted using bacteriostatic water. Ensure all equipment is sterile and follow standard laboratory protocols for peptide reconstitution. Add the bacteriostatic water slowly by injecting it against the side of the vial — do not shake. Gently swirl until the powder is fully dissolved.
This product is for laboratory research purposes only. All reconstitution should be performed under sterile conditions by qualified researchers.
Honestly? Pictures of peptide vials are pretty boring — they're very small, clear, and look almost identical to one another. AI imagery lets us make things more interesting and visually communicate what each compound is about.

Buy local, save local — it's that simple.
Pacific Northwest Purity doesn't have to mean premium pricing.
We are a small lab and can only produce so many vials at a time. To protect against mass purchasing and ensure fair access, we've restricted buy amounts to one kit per product per order.
These peptides are in high demand and sell out quickly. Check back soon — stock will be replenished.
If you need more than one kit, email us at orders@vancouverislandpeptides.com and we'll see what we can do.
Small batch synthesis keeps our quality high. We'd rather sell out than compromise on purity.
Yes! Since we don't produce growth hormone in our own lab, we've partnered with a trusted overseas supplier who maintains a domestic warehouse — verified GH without import risk or delays.
Stock and pricing varies — please email orders@vancouverislandpeptides.com to inquire about current availability.
Growth hormone is the one exception to our domestic lineup — and we only offer it through a supplier we personally trust.
