About four years ago a gnc I used to shop at sold these paper strips to test test. levels. The package said it was so you could see if your test. was at its monthly peak, but I would think it would be good for checking if gear is legit. Problem is I haven't seen them since and no one at gnc knows what I'm talking about (as usual). Does anyone know what I'm talking about, and if they are still being sold somewhere?
your sure it wasnt for ketones or lithmus paper for pH levels?
