Handling guides, short and sourced.
Practical guides from the Primara Labs team on reconstituting a vial, reading a U-100 syringe, bacteriostatic water, storage and reading a Janoshik report, plus a glossary. Every figure in them cites its source. None of them suggests an amount, a frequency or a protocol for any compound.

Reconstitution
- How to reconstitute a lyophilized peptide vialMaterials, clean technique, adding water down the vial wall, swirling rather than shaking, and labelling the vial.Updated 24 September 2026
- How to read a U-100 insulin syringeUnits to millilitres from 1 to 100, the three barrel sizes and their tick marks, U-40 versus U-100, and the common unit questions answered.Updated 24 September 2026
- Reconstitution calculatorConcentration, volume and syringe units from the numbers you enter. Arithmetic only.Tool
Handling & storage
- Bacteriostatic water vs sterile waterWhat the benzyl alcohol does, how plain sterile water is labelled, and why multi-draw vials use bacteriostatic water.Updated 24 September 2026
- Storing peptides: sealed, mixed and on deliveryLyophilized versus reconstituted, 2 to 8 °C, light and freezing, and what to do when the cold-chain parcel arrives.Updated 24 September 2026
