Reconstitution
Where a compounded drug parts company with an FDA-approved one, where 503A parts company with 503B, and which accreditation programs tell them apart.
What is Reconstitution?
Reconstitution means turning a freeze-dried powder into a liquid you can inject by adding a measured volume of sterile or bacteriostatic water.
The volume you add SETS the concentration, and the concentration sets how many syringe units your dose is. Getting it wrong scales the whole dose.
