Blend calculators
Blends put several compounds in one vial. One reading always contains every component in the label ratio, so these pages break each draw into its parts.
- KLOW blend calculator: GHK-Cu 50 mg + BPC-157 10 mg + TB-500 10 mg + KPV 10 mg
- GLOW blend calculator: GHK-Cu 50 mg + BPC-157 10 mg + TB-500 10 mg
- Custom blend calculator: enter any components.
Vials labeled in IU
HGH (somatropin) and hCG are labeled in international units rather than milligrams. The IU calculator does the same three steps in IU, and converts HGH between IU and mg at the WHO standard of 3 IU per mg.
Per-vial-size pages
For the compounds people search by vial size, each size has its own page with water options, charts at 1, 2 and 3 mL, per-draw capacity and draws per vial.
Retatrutide
Tirzepatide
Semaglutide
BPC-157
Converters
- mg to units at any concentration
- mcg to mg (divide by 1,000)
- Units to mL on U-100, U-50 and U-40 syringes
- How much bacteriostatic water for a target reading
How we choose what gets a page
A compound gets a calculator page when people search for it and its vials are sold in identifiable sizes. Vial sizes come from counting the sizes that appear repeatedly across public research-supplier catalogs (no seller is named or linked). A per-vial page exists only where people search by vial size.
