Compare peptide listings by normalizing the stated quantity, components and available documentation before looking at price. Similar names can describe different vial quantities, or a blend rather than a single compound.
Make each listing comparable
Copy what is actually displayed: the full product name, each named component, total or component-level milligrams as written, the price in CAD and the category. Never assume that two “10 mg” blends allocate that amount the same way unless the listing explicitly says so.
Use a side-by-side table
| Composition | Single compound or blend; the exact named components |
| Quantity | Stated vial milligrams, and whether allocation is explicit |
| Documents | Lot match, methods, dates and laboratory identity |
| Presentation | Illustrative image or verified package detail |
| Price | CAD price for the stated listing — not an assumed concentration |
Do not turn absence into a claim
If concentration, origin, sterility or a test result is not displayed, mark it “not stated.” A polished image is not documentation, and a purity result does not prove identity, peptide content, sterility or endotoxin status.[1][2]
Compare blends carefully
For a blend, determine whether the quantity describes the entire vial or separately states each component, and keep that wording intact in your notes. Dividing a total equally without explicit support creates a false specification and an inaccurate price comparison.
Choose the clearer record
- Prefer explicit component and quantity language.
- Check that any report identifies the same lot.
- Keep product-specific storage instructions with the record.
- Compare total cost only after the listing details align.
