I wanted to show how you can test the legitimacy of your hcg using a store bought pregnancy test. This is actually a dual purpose test, I wanted to test my hcg and I wanted to see if you could freeze hcg for storage. I froze this sample for over 3 weeks stored in a syringe. I used 500ius (20units) and mixed it with an additional 50 units of bacteriostatic water so there would be enough volume to saturate the pregnancy test. I added the extra water after the sample was defrosted. I injected the hcg slowly on the pregnancy test and let it sit per the instructions. As you can see in the pic the test was positive. I would like to do a test with a longer freeze time like 3 months and see what happens. The brand of the hcg is Ovulate-C, it was from World Pharma.
