Hello,

Testosterone is a schedule III controlled substance and per federal law can only be dispensed at a maximum of 30 day supply per fill. (Just a hint! Questions are usually based on real-life scenarios).

In addition: No vial, including the 10mL size, may have a day supply greater than 28 days after initial puncture as per USP Section 2 <797> non sterile compounding guidelines and manufacturer guidelines.

To solve this problem, set up cross multiplication.
(0.5 mL/2 weeks)=(1 mL)(x weeks)
x = 4 weeks = 28 days

280 Day Supply, however..., also..., and finally...
by: David

In this example, 0.5ml is injected every two weeks. As answered previously, this means that 1/2 ML every 2 weeks which is 1ml every 4 weeks (28 days).

So, for a 10ML bottle of testosterone cypionate, since this is 10 times 1ml, as a ratio, it would then be 10 times the 28 day supply, which is a 280 day supply.

However, if the expiration date on the package/bottle is earlier than the 280 days from when it is filled, then that would supersede the 280 days.

Also, if the testosterone has a beyond use date based on when the package is opened and the seal is broken, then this date would also supersede the 280 day supply.

And finally, if the patient has an insurance company which limits the days supply allowed, such as 30-day, 60-day, or 90-day supply, then this rx would have to be whichever one of those the insurance requires.

Okay thanks for the 1 ml bottle but what about a 10 ml bottle since my pharmacist is insisting we use that

0.5ML every two weeks = four week days supply for 1ML
by: David

1/2 ML every 2 weeks is equal to 1ML every 28 days.

So your days supply on 1ML is 28 Days.
