It’s fine it’s supposed to be in liquid lol, I’ve used that hcg numerous times. Even though it comes in liquid form it’s not reconstituted yet. I have no clue how they are able to keep it in liquid form, but that hcg has been around awhile and nobody seems to have issues with it.
Just reconstitute it and test it with the pregnancy test method. Also look up the manufacturer and then find hucog, I believe they explain on their website what preservatives are used to keep it stable at room temperature. I’m too lazy to try and find it so your on your own there haha
