Been a fan of the "Muscle Shake"…

Been a fan of the "Muscle Shake" protein blend for awhile. Giving the Force 440 a go this time around as well.
Easy to read website, easy to place your order, pick your shipping method....couldn't be easier.
always recommend the Protein Factory to friends.

I was disappointed that on the website…

I was disappointed that on the website it reported free shipping but when I placed my order, which was over $150.00, I was charged $5.99 for shipping.

The website is easily accessible and there are plenty of products to choose from plus an excellent rundown of how to use the products and analysis of how they work. I would have given a five star rating if not for the above complaint.

I just love your products.

I just love your products.

There is one exception though...
This page on your website: ".../best-whey-protein/"
(I couldn't put the full link above because it isn't allowed)

It states,
"Before I teach you exactly why you & anyone smart should ONLY INGEST Protein With A Supplement Facts Panel, and how to find the best whey protein, I will boldly state I do own ...Proteinfactory..., yes all my protein has a supplement facts panel."

The above statement needs to be corrected because it just is not a true statement.
Almost all of your protein powders show "Nutritional Facts" and not "Supplemental Facts".

I do like the results that I get from your products, Creatine (Creapure®) & Ion Exchange Whey Protein Isolate, and I will purchase again; I just wanted to point that out because it really bugged me.

I enjoy this company for its high quality protein and supplements. I recommend to spend the extra money on shipping if your not the patient type of person. Otherwise the products arrive on time or sometimes early. Thank you protein factory, and thank you alex rogers for providing me with quality products time and time again.

Excellent products

Excellent products. I really like the results.
One thing, if possible, I would like to see improved upon is quicker turn around on orders. Had a couple of orders stuck in processing for 3 weeks.

I've always liked Protein Factory…

I've always liked Protein Factory service and quality of products, I still do. That said, the Wisconsin Isolate Whey protein must have changed vendors. The powder is visibly different and has a very strange flavor. It tastes like plastic, very noticeable and unusual.

The Best in This Business

Shopped on the ProteinFactory.com web site twice in the last 10 days purchasing 4 supplements & waiting for another one to come back in stock. Always a pleasure doing business with ProteinFactory. Here's why:

• Web site is easy to navigate, from the shopping menu categories to the purchasing process.
• Product info is extensive — product descriptions, articles, book recommendations, videos, podcasts and research studies
• Company CEO hosts the Bodybuilding Supplements podcast & posts videos on TikTok.
• Company CEO is a bodybuilder himself with nearly 25 years experience inventing/formulating supplements
• Company CEO access — Can text/talk with to get questions answered during business hours.
• THEIR PRODUCTS WORK extremely well!

If you're serious about supplements, you shop at ProteinFactory.com — or you should. It's that simple for me.
