U-100 insulin syringe
Where a compounded drug parts company with an FDA-approved one, where 503A parts company with 503B, and which accreditation programs tell them apart.
Definition
The syringe shipped with almost every compounded GLP-1 vial: 100 units to 1 mL, so one unit is always 0.01 mL. ⛔ U-40 syringes also exist, are used in veterinary insulin, and will deliver 2.5 times what you intend if you read one as U-100. Check the barrel.
