I am on my P2D3 i.e. the first day of VLCD. When I went to get my injection today morning, I realised I have frozen it. It’s too hot this summer and I had raised my temperature of the refrigerator making the hcg vial partially frozen. Though I have thawed the vial with my hands and it is liquid again, I am wondering if it has lost its potency. My question is can I use this frozen hcg injection?
