- o**** (860)- Feedback left by buyer.Past 6 monthsVerified purchaseOMG, fast shipping! This is my first order (directly) from Sport Research. I've purchased other (SR) products from Costco this past year which seem to be working. I've never taken any of the supplements I just ordered/received on eBay, so time will tell how effective they will be (but so far, Sports Research seems to be a great company). I took advantage their (order 3 for _15%) discount offer, when I was only looking for a good Vitamin K supplement. Could not be happier so far. A+++Seller!
