## How does PepsTracker compare peptide prices fairly?

PepsTracker normalizes all prices to cost-per-milligram ($/mg). This is important because vendors sell peptides in different vial sizes — a $30 vial of BPC-157 at 5mg is actually more expensive than a $50 vial at 15mg. PepsTracker does this math automatically.

## Is PepsTracker free?

Yes. PepsTracker is completely free for researchers. The site earns revenue through affiliate commissions when users click through to vendor sites, at no additional cost to the buyer.

## How often are prices updated?

Prices are reviewed and updated daily. Last-updated dates are shown on each comparison result.
