Two Canadian research peptide suppliers, two very different catalogs. Here's how they line up on price, coverage, CoAs, and delivery — with pricing verified against peptidewarehouse.ca's public product pages on July 8, 2026.
You need retatrutide, tirzepatide, or modern peptides like 5-Amino-1MQ, SLU-PP, or Dihexa — none of which Peptide Warehouse carries. Or you're running longer, dose-response protocols where 10-vial kits win on unit economics.
You want to try one vial of BPC-157, CJC-1295, Ipamorelin, GHRP-2/6, or Melanotan without committing to a kit — or you need skincare products like copper peptide face cream. Their same-day fulfillment cutoff (2 pm EST) is also explicit.

Peptide Warehouse sells per vial. Helix North sells per 10-vial kit. To compare fairly, we normalize both to cost per milligram of peptide. Peptide Warehouse assumes a 5 mg standard vial at the listed sale price; Helix North uses current kit retail. All figures in CAD.
Helix North is roughly 4.5× cheaper per mg once you're buying more than one vial.
Helix North is roughly 3.7× cheaper per mg for extended tissue-repair protocols.
Helix North is roughly 3× cheaper per mg. Both stock 5 mg / 10 mg / 20 mg dose points.
Helix North is roughly 4× cheaper per mg for anti-inflammatory tripeptide research.
Helix North is ~30% cheaper per ml at the kit level. Both are USP-grade with 0.9% benzyl alcohol.
For a single-vial trial of a legacy peptide, Peptide Warehouse's cash outlay is lower and their same-day cutoff is explicit. For any multi-vial protocol, Helix North's kit format lands 3–5× cheaper per mg on overlapping SKUs. And for GLP-1 research, only Helix North has a stock.
As of July 2026, peptidewarehouse.ca's public product sitemap contains no retatrutide, no tirzepatide, no cagrilintide. If your research touches the GLP-1 / GIP / glucagon receptor family, Helix North is currently the only Canadian-domestic option among these two.

Methodology. Peptide Warehouse pricing and catalog scope were verified against their public product pages, category listings, and store product sitemap on 2026-07-08. Per-milligram costs assume a 5 mg standard vial at Peptide Warehouse's listed sale price; adjust proportionally for larger doses. Helix North figures reflect current kit-format retail as of the same date. Shipping and testing claims come from each supplier's public site copy; Peptide Warehouse review data is sourced from Trustpilot. This comparison is published by Helix North for research-buying decisions and is refreshed quarterly. Peptide Warehouse's own site — peptidewarehouse.ca — is the authoritative source for their current pricing and stock.
