Prices are the vendor's list price for one vial on the check date, in USD, before shipping. Ranked by price per mg; vendors that only sell multi-vial kits are listed after single-vial prices, at the per-vial price; sponsorship never changes the order. Links marked "Check price" may earn us a commission.

FAQ

DSIP price questions

Where is DSIP cheapest?

On October 20, 2026, the lowest DSIP price per mg among in-stock vendors was Orbitrex Peptides at $3.00/mg ($29.99 for 10 mg).

How much does DSIP cost per mg?

The median across 58 in-stock vendors was $7.20 per mg on October 20, 2026, with a range of $3.00 to $14.00.

How often are these prices checked?

Weekly. We read each price from the vendor's own product page and save every check, so each row shows the change since last week.

What does the COA badge mean?

The vendor publishes certificates of analysis (lab reports) for its products on its own site. 84% of the in-stock offers above come from vendors that do. Check that a report exists for the exact product and lot you order: a COA shows what a lab measured for one batch, not a guarantee about the vial you receive.
