Digestion + lean performance
Filtered to remove nearly all lactose, so it digests easily, absorbs quickly, and never leaves you feeling heavy.
Who It’s For:
Dairy makes you bloated or uncomfortable
You train and want fast, clean recovery
You want the most protein per calorie
Shop Whey Isolate
Whey

You mix it into food, smoothies, or morning coffee
You want protein as part of your everyday routine, not just after training
Fine with dairy, not lactose-sensitive
Shop Whey
Beef Protein
Hybrid protein
100% grass-fed beef. Zero dairy. One ingredient. All the recovery, none of the digestive compromise.

You follow a paleo, carnivore, or animal-based diet
You want to support joints and connective tissue alongside muscle

Both are fast-absorbing and ideal for muscle building and recovery. Whey Protein delivers 25g of protein per serving with a fuller nutritional profile. Whey Isolate delivers 30g per serving and is micro-filtered to less than 1g of lactose — the better choice if you're lactose-sensitive or want the leanest macro profile.
Whey Isolate is micro-filtered to under 1g of lactose per serving, making it well-tolerated by most lactose-sensitive individuals. If you need to avoid dairy entirely, Beef Protein Isolate is 100% dairy and lactose free.
Whey and Whey Isolate absorb quickly, making them ideal post-workout or between meals. Beef Protein works any time of day. If you want overnight recovery support, Beef Protein absorbs slowly over several hours and is best taken before bed.
Use the Promix Protein Calculator to find your daily protein target and get a recommendation based on your body, activity level, and goals — in under 60 seconds.
The Whey and Beef proteins are animal-derived. For a fully plant-based option, Promix offers a Vegan Protein Powder made from organic Canadian yellow peas — 25g of protein per serving, complete amino acid profile, no artificial anything.
