I have used it. It was a great blend. Just keep in mind, when you are squeezing in 2x as much hormone into 1cc of oil, there is a chancae that the added drug is going to cause more pain at the site of the injection. My suggestion is, if you use this product. I would use it only in larger muscles, in case you get pain from it ans make sure to rotate your sites. I would suggest taking 1cc per shot. If all of this sounds like a concern, you might want to just use the traditional EQ and Test seperately . That would always be the safetl
