How do you check from manufacturer ? You mail in the lot number right ? Which can be fabricated. Using the original ones.Never had any fake stuff from Jacked. I always check the products I buy from them via the manufacturer. Plus they have a 200% cashback incentive, if you have been sold fake supps.
Sportsone is the official distributors of ON, yes, but they charge the MOST. Don't know how you can say they have 'sweet prices'. They overcharge everything, and give you 0% discount. In fact, they have big stickers all over their shops that say "FIXED PRICE, NO BARGAINING". Meanwhile, I have a membership of Jacked, and they give me 10% discount on all supps (except those of Jym) for 1500 annually. So, I would never recommend Sportsone over Jacked.
I found their prices to be a lot less than jacked. Last time i went to jacked was 2 years back. The inner seal of whey was opened. Once pre workout was clotted well within expiry. I am not saying everything they have is fake. Some of the things at random.
GNC is cheapest btw.
Anyway even if sportsone is expensive i would rather go with official distributor. Since this thing can affect health and I am simply not willing to risk it.
The only way to really test supplements is a lab test.
