Hello.
I have recently purchased some bulk Powders.Tryptophan,Dlpa,Rhodiola,Piracetam, in specific.Does anyone know the characteristics of these powders as I do not know how to identify them.
Is it normal for a bulk powder like Tryptophan to have a vinegary smell to it?
How can they be stored for use in the long-term without them spoiling?
Is Ziplock double seal bags ok to store them in,in a humid climate and should the storage area be free of any micro contaminants?
Thanks.
