Really like this one honestly. Run it on a hundred day cycle, twice yearly, 20mg kit split into 2mg nightly. Never had a sting from it, and the batches I've currently got tested clean. Course, I also don't react with a sting to NAD, glutathione, or any of the growth stacks either, lol.
Haha, personally nicknamed that one the bee sting special. My very first dose came from a 500mg bottle mixed with just 2ml of bac water. Genuinely hurt like an insect got me. Learned my lesson after that.
