## Key facts
- Concentration mg/mL = mg in vial ÷ mL of solvent. 5 mg in 2 mL = 2.5 mg/mL = 2,500 mcg/mL.
- Draw mL = amount ÷ concentration (same mass unit). 250 mcg ÷ 2,500 mcg/mL = 0.1 mL.
- U-100 insulin syringe: 100 units per mL, so 0.1 mL = 10 units. U-40: 40 units per mL, so 0.1 mL = 4 units. Barrel size (0.3/0.5/1 mL) does not change the scale.
- Doses per vial = vial mg ÷ mg per dose; the water volume does not change it. 5 mg ÷ 0.25 mg = 20 doses.
- 1 mg = 1,000 mcg; 1 mL = 1,000 µL; 1 U-100 unit = 10 µL. IU has no universal mg equivalent.

## Guides
- [Seven Reconstitution Math Mistakes and How to Catch Them](https://peptidecalculations.org/guides/common-reconstitution-mistakes/): Seven arithmetic errors in peptide reconstitution, each with the wrong and right number side by side: mcg vs mg, pack mass, U-40, barrel size and rounding.
- [Cost per mg and Cost per Draw: How to Compare Peptide Vials on Price](https://peptidecalculations.org/guides/cost-per-mg-and-cost-per-draw/): Cost per mg is vial price divided by mg in the vial; cost per draw is cost per mg times mg per draw. A worked 5 mg vs 10 mg comparison, with packs and shipping.
- [GLP-1 Titration Schedules Compared: Semaglutide, Tirzepatide, Retatrutide, Cagrilintide](https://peptidecalculations.org/guides/glp-1-titration-semaglutide-tirzepatide-retatrutide/): Week-by-week label schedules for Wegovy, Ozempic and Zepbound beside the retatrutide and cagrilintide trial doses, plus the math that turns a step into units.
- [How Long Reconstituted Peptides Last: Storage, Fridge Time and Bacteriostatic Water](https://peptidecalculations.org/guides/how-long-do-reconstituted-peptides-last/): Powder keeps for years frozen; a mixed vial is a 28-day multi-dose vial by USP convention. Bacteriostatic water, fridge temps, freezing, light and degradation.
- [How Many Draws Are in a Vial? Vial Yield Math](https://peptidecalculations.org/guides/how-many-draws-in-a-vial/): Draws per vial equals vial mass divided by mass per draw. A yield table for 2, 5 and 10 mg vials, why water volume does not change the count, and rounding down.
- [How Much Bacteriostatic Water to Add to a Peptide Vial (and Why the Volume Is Your Choice)](https://peptidecalculations.org/guides/how-much-bacteriostatic-water-to-add/): The water volume sets the concentration, not the mass. Picking a volume that gives round syringe units, a table for 2, 5 and 10 mg vials, and capacity limits.
- [How to Inject Peptides Subcutaneously: Sites, Needles, Steps](https://peptidecalculations.org/guides/how-to-inject-peptides-subcutaneously/): Which insulin syringe to use, where to inject (abdomen, thigh, back of arm), site rotation, 45 vs 90 degrees, why no aspiration, and needle disposal.
- [How to Read a Peptide Dosage Chart (and Turn It Into Syringe Units)](https://peptidecalculations.org/guides/how-to-read-a-peptide-dosage-chart/): What a dose range means, the three basis types (label, trial, commonly reported), weekly vs daily totals, and two worked conversions from a chart row to units.
- [How to Use a Peptide Reconstitution Calculator (Step by Step)](https://peptidecalculations.org/guides/how-to-use-a-peptide-reconstitution-calculator/): The three inputs, the three outputs and the formula behind every peptide reconstitution calculator, with two worked examples and the input mistakes to check.
- [Insulin Syringe Units Explained: U-100, 0.3 mL, 0.5 mL and 1 mL Barrels](https://peptidecalculations.org/guides/insulin-syringe-units-explained/): What a unit means on a U-100 insulin syringe, how 0.3 mL, 0.5 mL and 1 mL barrels are marked, the U-40 trap, and a units-to-mL table for reading any draw.
- [mcg vs mg: The Conversion Every Reconstitution Depends On](https://peptidecalculations.org/guides/mcg-vs-mg/): 1 mg equals 1,000 mcg, and µg means the same as mcg. Where the 1,000× mistake shows up in reconstitution math, a conversion table, and how mcg/mL is derived.
- [Peptide Cycle Length: How Long to Run BPC-157, TB-500, GH Secretagogues and GLP-1s](https://peptidecalculations.org/guides/peptide-cycle-length-and-breaks/): Why GLP-1s run continuously by label, why GH secretagogues get breaks (the hexarelin data), and why BPC-157 and TB-500 cycle lengths are convention only.
- [Reading a Certificate of Analysis for Mass: Net Peptide Content vs Label Claim](https://peptidecalculations.org/guides/reading-a-coa-for-mass/): What a third-party COA reports, why 99% purity is not 5 mg of peptide, how net peptide content differs from label mass, and how it changes the math.
