Instructions: Undergraduate students may enroll in a maximum of 16 units throughout the Early/Final Priority Period of registration. During Open Registration, a maximum of 19 units is allowed. All requests for 20 units or more must be approved by the Dean of the College in which your major is housed.
You should always refrigerate any bottles you fill for later feedings to prevent bacteria from growing, as well as any open containers of ready-to-feed or concentrate formula. Throw away any mixed formula after 24 hours and any open ready-to-feed or concentrate formula after 48 hours.
A bottle is supposed to be fresh for 28 days after you take it out of the fridge and start using it. As long as it wasn't in direct sunlight you should be okay. Cold insulin kind of hurts when you inject it-I never store mine in the fridge except the bottles I haven't opened yet.
