There is Whisky shots,bourbon shots,and ouch they just stuck a needle in my back shots lol..sorry for being a smart butt lol..best advice i can give you is look them up online because im a smart a__ __ not a doctor, smiles!

Sorry, I posted on your wall about the different things. There's actually a couple responses :)

Was told the shots last 6 months to to 2 years,if they in fact work for you and your particular pains
