Road Glide I'm surprised, and concerned, by the comment about Costco / Kirkland Vitamins which ones are you referring to? I thought they tested very well with people like consumer labs which I pay for a subscription for because I believe them to be very impartial. I'm not a Costco defender just a regular customer who has been trusting there brand of vitamins for a number of years.
I think most Costco sups are good quality. Consumer Labs has not tested Pycnogenol yet.
There's no Costco near my place, but I've always heard their supplements are good quality.
