What you have there is a total of 15,000iu's (3 amps of 5,000iu's each). You need to order one empty sterile vial and one vial of Bacteriostatic Water from Researchology. Pull out 1ml of the Bact. water and slowly inject it down the side one one of the amps, the powder will turn to a liquid form. Draw the liquid up into the syringe and inject it into the empty sterile vile. Now, add 4ml of Bac Water to the solution and you now have 1,000iu's/ml.
Do not mix up more than 1 amp at a time, 1 should last you 30-60 days at 250-500iu's every 3-4 days which is the reccommended dosage by most. Oh, and forget the water that comes with it if you order the Bac water from R'ology.
