I bought 100 grams eight years ago and just ran out, so I ordered another 100 grams. I seems just like the last purchase, no change in strength, must be stable. I stored it in semi darkness, with wide changes in temperature. No bad effects noted.

years. Always have received a quality product with no complaints...
ever! They even gave me tips on how to store it, very helpful.
