I previously purchased a 10-pack from a different supplier a few months back and had a good experience with them. When that supplier was out of stock, I turned to PS to buy more, in a 20 pack. To my suprise, the batch was not multicolored, and only had yellow and green gummies, where as the 10-pack I previously bought had 5 different colors. The color of the gummies didn't matter much to me, however even after 2 gummies (800mg) I felt no effects whatsoever, whereas with the previous batch I got I did. This batch simply wasn't as potent as it should have been. These gummies too were more dried out and less soft than the first pack I bought, which makes me think they were old/stale. PS was very helpful in remedying the problem, and passed along to the vendor the issues I reported. I intend to try buying another batch again perhaps in a few months, because it's genuinely a good product, however I am a user that prefers reliability with my dosing.
