Vaporizor Oils?

When I purchased a vaporizer back about 5 years ago, it came with some drops that I used to refresh my bowls. Generally the bowls dont hit too strongly and only last a few pulls but when I put these drops it they enhance it and I makes it a ton better. These drops didnt come with any brand or anything on it. Does anyone know what this is? Thanks

Anyone know? If anyone vapes this is an awesome product. I use it every time
