Seems to be only one ester of EQ. I’m sure the answer is pretty well known but I’m out of the loop
Both cyp and ace are available. Nobody uses them because they come with some pretty nasty PIP, and since demand is low the number of labs that carry either of them are much lower than the more traditional ester.
Bold cyp hard to keep from crashing and bold ace had horrid Pip.
Just be patient and run it 16 weeks
