Definitely look up a guide on how best to mix the lube when you start out. My first patch ended up not mixing well and I had to scoop the un-mixed part out, the second one was too thin and runny. Of course like Goldilocks, the third batch was JUST right after looking up a proper guide and using measuring spoons. 1 tablespoon per 500ml was around the sweet spot and is also equal to two caps of powder.
This lube also answered two main reasons I didn't take part in anal play that often. The price of lube is handled due to price per volume and the idea that it would keep fine for a while so there was no rush. Now I am encouraged to at least do some anal stretching play daily after making a batch to use it before it goes bad and needs to be thrown out.
