bromantane expiry date - science bio
i have some bromantane from science bio (before they shutdown apparently )
the ones that i have ( 5 bottles ) i bought more than 1.5 yr ago
now , apparently some of them got crystalized as you can see in the pictures ,
.
- i tried warm and hot bathing on two of them , did not remove any crystalized
1- is there any expiry date for it ?
2- did i lost all my 5 bottles ?
3- is it safe to use it in that form ?
4- is there any smell i should try to notice to identify if i lost all of them or not ?
