You mix it with bacteriostatic water. Most amps come in 5000iu powder form, mix it with about 2ml of bac water and 1/10th cc is 250 iu. Refrigerate after mixing, only use a sterile vial, and inject sub-Q. So no you don't mix it with test. Also many hcg amps come with sterile water... Don't use it, get bacteriostatic water.
