Canada's HGH &
Peptide Source.

Great Canadian Peptides was founded with one mission: to provide researchers across Canada with the highest-quality HGH and research peptides — Canadian owned, independently tested, and fulfilled entirely within our borders. All products are for research use only.

Great Canadian Peptides research compounds in a Canadian laboratory
Canadian Laboratory Tested

Our Commitment to Quality

Our flagship product, HGH 191AA Somatropin, is the complete 191-amino acid sequence, independently verified before every shipment. Alongside HGH, we carry a growing catalogue of research-grade peptides including GLP-1, GLP-2, GLP-3, and GHK-Cu.

Every product undergoes rigorous third-party testing before it reaches you. We partner exclusively with certified Canadian laboratories that meet or exceed research-grade analytical standards, ensuring every batch achieves our 99.7% average purity benchmark.

We oversee testing and fulfillment end to end, giving researchers complete traceability and confidence in what they receive.

All products sold by Great Canadian Peptides are intended strictly for in vitro laboratory research purposes only. They are not for human or animal consumption and have not been approved by Health Canada for therapeutic use.

Why Canada?

For us, independent verification is a quality assurance decision, not a marketing line. Every batch is tested by a certified Canadian laboratory before it ships, giving researchers stricter oversight and faster, verified logistics. When you order from Great Canadian Peptides, your product is tested here and shipped from here.

99.7% Avg Purity

Independently verified purity across every batch, every product.

HPLC Verified

High-performance liquid chromatography confirms sequence integrity.

3rd Party Tested

We don't rely on in-house testing alone; every batch goes to independent labs.

Canadian Operations

Every batch tested and shipped from within Canada.

Transparent COAs

Full Certificates of Analysis available for every product lot.

Competitive Pricing

Premium quality doesn't have to mean premium markups.

Why Choose GCP

We started as customers.
We couldn't find a source
worth trusting, so we built one.

Every competitor we found had zero transparency, charged premium prices, and skipped independent testing. GCP exists to fix that.

What sets us apart

Every single batch.
Tested individually.

Most suppliers test once and re-sell for months. We send every individual batch to Janoshik Analytical before it ships. Not shared, not estimated, not skipped.

Tested here.
Shipped from here.

No grey-market shortcuts. When you order from GCP your product is independently verified and dispatched entirely within Canada. That's a standard few others in this space can match.

The best prices
in Canada.

We built this because we couldn't find a supplier worth trusting at a fair price. Premium quality doesn't require a premium markup. We keep our margins lean and pass the savings to you.

3. Estimated Delivery Times

Once dispatched, estimated delivery times within Canada are 3–7 business days, depending on your location. Remote or rural addresses may require additional transit time. Delivery estimates are not guaranteed and may be affected by carrier delays, weather, or other circumstances outside our control.

We will update this policy as we finalize carrier partnerships and are able to provide more precise regional estimates.

4. Shipping Rates

Free shipping is applied automatically to all orders totalling $190 CAD or more (before applicable taxes). Orders below $190 CAD will be charged a shipping fee, which will be calculated and displayed at checkout. Shipping rates are subject to change and will be confirmed before you complete payment.

5. Carriers

We ship via trusted Canadian carriers. Carrier selection may vary by order size, weight, and destination. Tracking information will be provided where available once your order has been dispatched.

Refund Policy

Last updated: July 1, 2025  ·  Great Canadian Peptides  ·  Alberta, Canada

Important — Please Read Before Ordering

Due to the nature of research peptide products, all sales are considered final. We do not accept returns. Please review your order carefully before completing purchase.

1. All Sales Final

All purchases from Great Canadian Peptides are final. We do not accept returns or exchanges under any circumstances. This policy exists because our products are research-grade lyophilized peptides — once shipped, we cannot verify storage conditions or chain of custody, and cannot resell returned product.

2. Store Credit

While we do not offer cash refunds, we may, at our sole discretion, issue store credit depending on the circumstances of your issue. Store credit eligibility is assessed on a case-by-case basis. To request consideration for store credit, contact us within 3 days of delivery with your order details and a description of the problem.

3. Damaged or Incorrect Orders

If you receive an order that is damaged in transit or contains an incorrect product, contact us within 3 days of delivery at contact@greatcanadianpeptides.ca. Please include your order number, a description of the issue, and photos where applicable. In these cases, we will work to resolve the issue, which may include resending the correct or replacement product at our discretion.

4. Reporting Window

All issues — including damaged goods, incorrect items, or missing products — must be reported within 3 calendar days of the delivery date as indicated by carrier tracking. Issues reported outside this window will not be eligible for any resolution, including store credit or resending.

5. Shipping Costs

Shipping costs are non-refundable under all circumstances. In the event that we resend an order due to a confirmed error on our part, re-shipment costs will be covered by Great Canadian Peptides.

6. Order Cancellations

Orders may be cancelled only if they have not yet been dispatched. If you need to cancel an order, contact us immediately at contact@greatcanadianpeptides.ca. Once an order has been shipped, it cannot be cancelled and this refund policy applies.

7. Research Use Acknowledgement

By completing a purchase, the buyer acknowledges that all products are sold strictly for lawful laboratory research purposes, that they have reviewed and agreed to our Terms of Service, and that they understand no refund will be issued on the basis of dissatisfaction related to any use of the product outside of its intended research purpose.

Syringe Reading
Laboratory calculation tool only. This tool performs a mathematical volume conversion for research purposes only. It does not provide dosing, administration, injection, preparation, or treatment instructions, and is not a substitute for professional judgment. Unit readings use the standard U-100 insulin syringe scale (1 mL = 100 units). All products referenced are for in vitro laboratory research use only — not for human or animal consumption, and not approved by Health Canada for therapeutic use. Verify all calculations independently before any laboratory use. Great Canadian Peptides is not responsible for errors resulting from incorrect inputs.

How This Peptide Dosage Calculator Works

Reconstituted peptide vials don't come pre-measured — the concentration depends entirely on how much bacteriostatic water was added to the lyophilized powder. This calculator does that math for you: enter the total peptide amount in the vial, how much bacteriostatic water you used, your syringe size, and the amount you're working with, and it converts that directly into a syringe reading in units.

The underlying formula is simple — bacteriostatic water (mL) divided by total peptide (mg) gives you mL per 1 mg — but doing it by hand for every vial size and target amount is where measurement errors creep in. This tool removes that step entirely.

Why Accurate Peptide Dosing Math Matters

A small error in reconstitution math compounds every time you draw from the same vial. Getting the concentration calculation right once, at the start, is what keeps every subsequent measurement from that vial consistent — which matters for any research protocol that depends on repeatable, comparable volumes.

For the full step-by-step reconstitution process this calculator is built around, see our guide to reconstituting peptides, or read about what bacteriostatic water actually is and why it's used instead of plain sterile water.

Frequently Asked Questions

What is a peptide dosage calculator?

A peptide dosage calculator (also called a peptide reconstitution calculator or peptide syringe calculator) converts a vial's total peptide amount and the bacteriostatic water added into a concentration, then tells you exactly how many units to draw on a syringe for any target amount.

How do I calculate my peptide dosage after reconstitution?

Divide the bacteriostatic water (mL) by the total peptide in the vial (mg) to get mL per 1 mg, then multiply that by your target amount to get the exact volume to draw. This calculator does that automatically once you enter your vial and syringe details above.

Does this work for any peptide?

Yes — this is a unit-conversion calculator based on vial size and bacteriostatic water volume, so it applies the same way regardless of which specific compound is in the vial.

How do I reconstitute my peptides?

Reconstitution means adding bacteriostatic water to a lyophilized peptide vial to bring it into solution. Add the water through the rubber stopper, let it run gently down the vial wall, then gently swirl (don't shake) until dissolved. Use our Reconstitution & Draw Calculator for exact volumes for your vial and dose.

Why e-Transfer as payment?

Due to the nature of the research peptide industry, many payment processors — PayPal, Stripe, standard card processors — classify these businesses as "high-risk" and may limit or decline service, even when products are sold strictly for research use. Interac e-Transfer lets us accept secure, bank-verified payments without that restriction. Card is still available at checkout if you'd prefer it.

Is bacteriostatic water required?

Yes — bacteriostatic water is needed to properly reconstitute lyophilized peptides into solution, a step many researchers don't realize is required. Within standard laboratory practice, its preservative also helps keep multi-use research vials stable for longer. We carry it alongside our peptides for this reason.

Do you test all your products?

Yes — every single batch is independently tested and analyzed before it ships, not just once per product. A Certificate of Analysis (COA) is available for every batch right on the product page, and additional COAs can be specially requested any time.

How fast do orders ship?

Once payment is confirmed, your order ships out the next business day — 2 business days at the latest.

Will I get an order confirmation?

Yes — you'll get an email at every step: order confirmation, payment confirmation, and tracking once it ships. You can also view your full order history any time from your account.
