Hello guys. First time posting here.

My question is - how long can I refrigerate an already mixed hcg (by Pregnyl)?

I'm planning on running the hcg for 12 weeks at 250iu twice a week in conjuction with my test enanthate (600mg/wk) and deca (500mg/wk).

I have a 5000iu amp of hcg but from what I read on different boards you can only expect the potency of hcg to linger around 30 days or so. But I read somewhere (Anthony Roberts?) that one can use the mixed hcg for 10 weeks.

Do I need to get 2 more amps of hcg (making a total of 3 amps) to be able to run for the 12 weeks, assuming the shelf life is only 30days?

Or is it safe to assume it will last for 10 weeks?

Thank you for your help.
