Does anyone know if creatine ever goes bad, or if it expires after a given time period. I bought some about a year ago and still have some left, is it okay to use still? Thanks.
I’ve had some sitting around a little longer than that and it seemed fine when I used it. I am sure it would eventually expire, and from what I understand if it is mixed in water already it would go bad much much faster.
If your creatine has a “delivery system”, meaning some form of sugar, then there could be a concern about spoiling. In such cases, you can usually tell the product has gone bad. There will be a degree of discoloration visible (usually a non uniform darkening of the powder).
I wouldn’t use it. I don’t like using a creatine 6+ months after I bought it to make sure it’s not creatinine.
With regards to creatinine, what is it and why would it be bad for me to be ingesting this?
Are there any source where i could find out about this question and get a definite answer?
