I’m so sorry to hear this. To be honest, I’m not quite sure – it likely does have potency left as of now, I’m just not sure how much more quickly it starts degrading at room temperature like that vs. being in the fridge. It seems likely that it may be okay at least for a time – it may have sped up the overall potency degrading so that you may need to mix a new vial sooner though than otherwise – again I’m just guessing but if you continue to use the same vial, definitely pay attention to your hunger symptoms and if changing the dose doesn’t fix that, I would consider getting/mixing a new vial.
To give you just a little reference point, I once had a vial of mixed hCG shipped to me by a patient, and while it was packed with a few cold packs, by the time it arrived at my home, in the summer, it had been 3-4 days in transit, in warm temperatures. At this point, amazingly, the hCG vial STILL tested positive on an hCG pregnancy test strip- so it’s possible you may be just fine!
