Trustworthy firm. I enjoy the informative articles, science/research based approach and candid mantra of those behind proteinfactory.com. I spent couple days delving into each product I purchased. A lot of effort is put into full descriptions both written and podcast for most products offered. I reached out via email directly to the owner Alex and he, or someone repping him, thoroughly answered my question within an hour…on a Saturday. That alone resulted in gaining my trust and over $200 purchase. Keep up the great work guys!

The Protein Factory is my go to Muscle Factory... I have been buying proteins from Alex since he first established the Protein Factory in 1998. No company in the USA sells higher quality proteins and no other company offers as wide a variety of protein types under one brand. Try finding another major player who sells Whey Isolate, Pepto Pro and Bio Serum Proteins on their websites--you won't. Try finding genuine Creapure Creatine--good luck (hint...Al has it). Pricing is very competitive and shipping has always been timely. Thanks, Alex. Respect, Mark Rustad

Excellent products The whey protein is pure with no Added ingredients like other over the counter protein products you find in the stores which have sugar and Other ingredients which can actually cause weight gain. The protein factory by far has the best products you Could find. It is top quality.The chocolate and vanilla flavors taste like drinking a milkshake if added with banana and almond milk and ice.or a banana with another fruit. Best taste on the market!

STOLE MY MONEY Service has been getting worse and worse and this time THEY COMPLETELY STOLE MY MONEY. 4 attempts by email and text to check the status of my order and NO RESPONSE AT ALL. This company is totally tanking into the toilet bowl. They were good when the owner Alex had a passion for business 20 years ago. Now evidently he couldn't care less about the his customers, and even stealing money now. STAY AWAY FROM THIS COMPANY. There are many great companies very eager to please

Go for the 100% Whey Isolate. It's worth the Cost. I've been ordering from Protein Factory for years. Great, clean product, good service and fast shipping. Recently the cost went up (due to dairy prices I'm sure) for the 100% Wisconsin Whey Isolate so I cheaped out and got the Mega Whey instead. the MegaWhey is 'fine'. It's still better than most grocery store brands, but it doesn't mix as cleanly or have as clean a taste. I will go back to the Wisconsin in the future.
