These peptide blends in Canada combine two to four research compounds in a single vial, shipped as freeze-dried powder, strictly for laboratory research use only. For a lab ordering by volume, a blend saves bench time and vial count but makes comparison and characterisation harder — understand the trade-off before weighing one against single-compound stock.
Peptide blends in Canada: component breakdown
Each blend listing shows the mass of every component, since the total printed on the vial reveals nothing about how much of an individual compound it holds:
- BPC-157 & TB-500 10 mg: 5 mg of each compound
- BPC-157 & TB-500 20 mg: 10 mg of each compound
- CJC-1295 (no DAC) & Ipamorelin 10 mg: 5 mg of each, with CJC-1295 in its non-DAC form
- GLOW 70 mg: 50 mg GHK-Cu, plus 10 mg each of BPC-157 and TB-500
- KLOW 80 mg: the same three as GLOW (50 mg GHK-Cu, 10 mg each of BPC-157 and TB-500) plus 10 mg KPV
Pricing a blend against single vials
Comparing a blend's price with a single-compound vial only makes sense once the split is known. Take GLOW: a 70 mg total looks generous beside a 10 mg vial, until you see that GHK-Cu accounts for 50 mg of it. Procurement teams working out cost per milligram should do the sum component by component — see the limits of per-milligram price comparisons and KLOW's components and their research context. Blends and single vials combine toward the same quantity tiers.
Characterising a multi-component vial
For a single compound, a certificate gives one purity number against one target mass. A blend needs a separate result for each component, which introduces problems that do not arise with a single vial:
- Overlapping peaks. Components of similar hydrophobicity may co-elute on a reverse-phase column, making a blend's chromatogram harder to resolve than either compound's on its own.
- Proving the ratio. Showing that the vial holds the stated proportions is a quantitative measurement, separate from showing that each component is pure.
- Uneven stability. Components degrade at different rates — GHK-Cu contains redox-active copper, BPC-157 does not — so the least stable component sets the blend's practical shelf life.
- No attribution. An unexpected result in a blend cannot be pinned on one component. If that matters to the study, buy single vials and combine them at the bench instead.

Identity data, certificates and storage
Products are third-party tested, and published certificates are on the COAs page in the form the lab issued them, with vials matched by cap and crimp colour. Each listing also gives identity data per component: sequence, formula, mass, CAS number and a PubChem link. Store every blend to suit its least stable component — see stability of lyophilised peptides.
