Aloha, try going to Pr. Monday June 30th on I-hub and go down to 3rd paragraph an something about a doctor doing you with Botox , I not sure if that's what you referring to.
it's been around for years as you probably know. The military used it to save time and not deal with people with needle problems.....however, it was a complex high pressure system that measured and fired a shot in a matter of seconds. Kinda a 'don't try this at home' unit....lol We have a rough road ahead I fear.......I want to see it in action with real doctor's on hand to give their opinions of pros and cons.
