Native Whey Protein Isolate- After A LOT of research on whey protein, I bought this one. Dissolves really well, tastes good. Even the plain one tastes good - like a creamy milk. No stomach issues. Overall a great product and worth the price. The cheap shipping option even made the price somewhat competitive to some of the cheaper proteins that charge more for shipping (considering the weight).

On April 11th, I purchased the Caldrol 500. My package was given a tracking number, but USPS never received it. Customer service is only available via text or email; the owner seldom responds to customer concerns. Shipping is extremely slow, as well. My usual approach to reviewing isn't to leave bad reviews, but the shipping and customer service is so bad that I'm compelled to do so. As of this review, I'm still awaiting my package, and the owner won't even respond with a tracking number. I sent a complaint through Paypal to get a refund because I am tired of dealing with this company.

I was charged for a ebook and never received it

I used $20 fastest shipping (1-4 days) for the ZF goat colostrum and it's going to take 11 days. I emailed them about a refund for the fast shipping and haven't gotten a response. I have Crohn's, which this product helps at least ease my mind about (and plan on ordering as much as possible since I've felt improvements here and there), so going so long without it isn't a great feeling. I ordered with 1-7 day shipping last time, and got it pretty late, too, possibly a day or so earlier even than with the 1-4 day shipping. Each time during these two orders, I feel like I had to email them each time before they shipped it out—though this could've been coincidence (and thus maybe they haven't acknowledged me writing to them). I thought about giving 2/5 stars for service, if it wasn't for feeling good about the product, etc.

I will have to say that this protein is high quality.

I have ordered my LJ 100 Tongkat Ali on the 10th of February. Now is 23rd of April and I still haven't received it. I have contacted customer service on April 2nd and never received an answer. The tracking number shows that the package went all the way to my country and then returned back to their shop. I would certainly appreciate if someone finally responds to my emails and start communicating with me as I haven't received the product that I purchased, nor the money that I paid for it. Order number: 219991

Hello, sorry about your shipment but we cannot control the customs process in your country of the Czech Republic. The tracking clearly shows we shipped your order, but unfortunately it was returned to us. We cannot refund you until, we receive it back. And as the tracking clearly shows we have not received it yet. But the good news is that we should have it this week.
All there products are effective and good prices

I’ve always had a good experience with this company. I really enjoy the products and feel that they are superior and pure. Only thing that I don’t like is the shipping seems like it takes a long time to get from New Jersey to New York.
