HCG and BAC water expiry question

Hi guys,

It’s my first time using HCG. I have been on TRT for like 4 years now, in my initial pack from Dr I got HCG sets. 3x 5,000 IU with 1ml bac water, I didn’t use them.

HCG expiry is 2023 (unmixed powder)
BAC water expiry is 07/2025.

Is it good to use? I have stored it in dark cupboard. Am I ok to mix 5,000 iu with 1ml bac water provided? I plan to administer 500iu 2x per week, so 0.1ml works fine for me, just cautious about safety and HCG expiry and BAC water expiry? Nothing is opened and was stored well
