If it’s been more than 2 weeks since being on hCG, it would be good to do the loading phase again. And remember, you don’t have to load dirty, you can load clean to both minimize the loading gain as well as to overall feel better and have fewer cravings the first week.
Regarding using the same hCG vial:
Once hCG is mixed into the solution, it’s potency begins to gradually degrade. Exactly at what rate we don’t know, but the general consensus is to use your vial of hCG within about 3-4 weeks. After that it seems that the potency may not be very good and could cause both issues with weight loss and hunger.
If you’re really in a pinch and have no other option, you could try taking a large amount of hCG in your syringe to make up for the lost potency, but I don’t think this is the ideal route.
I hope that helps you decide what you want to do!
