How we price.

One unit. £/mg.

Every vendor lists different vial sizes. We normalise all prices to GBP per milligram so that a 5 mg vial at £45 and a 10 mg vial at $79 can be compared directly. Shipping and vendor fees are excluded. Capsule, topical, sublingual, and oral-solution offers do not participate in £/mg rankings — their raw mg is not bioequivalent to an injectable vial's mg.

Daily FX.

Foreign currencies are converted at 09:00 GMT using mid-market rates. We snapshot once a day, not live. The rates in use: GBP 1, USD 0.79, EUR 0.87. Refreshed when drift exceeds 5%.

Consistency tiering.

Vendors are tiered A/B/C from consistency data: COA cadence (per-batch, historical, or on-request), community rating, time on the market. This is a display-only signal — ranking order is not affected by tier.

Ranking.

The Index sorts on £/mg alone for each peptide's dominant form factor. Tier, country, rating, and in-stock status are display signals. Affiliate commission has no effect on ranking order.

Research-only.

All listed compounds are sold and discussed as research chemicals. Nothing here is medical advice; Pepwizard does not facilitate therapeutic use. Age-gated access (18+) is required to view content.
