How to Compare Product Specifications

Direct answer: mg, mg/mL, mL and "units per box" measure different things and cannot be compared directly. Before comparing price or value across two products, confirm which of these four figures each supplier is actually quoting.
Four units, four different questions
| Unit | Question it answers |
|---|---|
| mg (total) | How much material (by weight) is in the container — may be total formulation weight, not necessarily net active content |
| mg/mL (concentration) | How concentrated the material is per unit volume — two products with the same total mg but different fill volume have different concentrations |
| mL (fill volume) | How much liquid/reconstituted volume is in the container — not itself a measure of active content |
| Units per box | How many individual vials/syringes/ampoules are packed together — changes your per-unit price calculation even if the per-unit spec is identical |
A twin-vial (double-bottle) product should never be compared by capacity directly against a single-vial product without first confirming whether the quoted figure is per bottle or combined across both bottles.
Worked example: two SKUs, same descriptive name, unconfirmed identity
Our own product catalogue currently contains a real, unresolved case worth understanding: "Friderm B Body" (10 mL, HA, in syringe) and a separate catalogue entry, "HA 10 mL Booster Syringe", are both 10 mL hyaluronic acid products in syringe format. Internally, it has not yet been confirmed whether these are the same SKU under two names, or genuinely two different products. We do not merge them into one listing, and we do not assume they are different — both product pages carry this same open question until it is resolved. We use this as a live example of exactly the mistake to avoid: don't assume two similarly-named/sized SKUs are identical (or different) without supplier confirmation, even when you're buying from a single catalogue, let alone comparing across suppliers.
How to request a comparable spec table from any supplier
- Ask for mg, mg/mL and mL as three separate confirmed figures, not just one of them
- Ask whether the mg figure is total formulation weight or net active content
- Ask for units-per-box and confirm whether quoted pricing is per unit or per box
- For twin-vial/combination products, ask for each component's figure separately
FAQ
Can I compare two products just by their total mg figure?
Not reliably — mg alone doesn't tell you concentration (mg/mL) or fill volume (mL), and may not specify whether it's total weight or net active content. Ask for all relevant figures separately.
Why does FRIDERM Pro have two 10 mL HA products that might be the same thing?
"Friderm B Body" and "HA 10 mL Booster Syringe" are both 10 mL HA syringe records whose SKU identity is still being verified. We disclose this openly rather than guess — both pages carry the same caveat until internally confirmed, and we use it as a real example of why buyers should always verify SKU identity rather than assume from naming or size alone.
How should I compare a twin-vial product to a single-vial product?
Confirm whether the quoted capacity is per vial or combined, and compare like-for-like — never assume a twin-vial's total equals a single vial's labeled capacity.
