I just found some old tribulus capsules and yohimbe capsules in my medicine cabinet. I bought them about a year and a half ago, but only used about half of each bottle. I was going to start taking them again, but noticed that the contents of each capsule were hard and shrunken. Would these pills still be effective, or even safe?
Did you check the expiration date?
One said that it expered in February, the other one said it will not expire until November. How do they get these dates anyway?
Those dates are based on quality control curves. The February item is probably still good, and the other one definitely is still good.
