Most manufacturers do “quality testing” by randomly testing products on their way out of the factory.

We triple quality check every supplement we sell. That means we:
• Test every batch
• Test our raw ingredients AND finished formula
• Utilize 3rd party testing through external labs

The result? You can trust that every supplement we send you is potent, pure, and bioavailable until you’re ready to use it.

What’s Inside:

Creatine Monohydrate

The gold standard. Scientifically proven from decades of research, and as close to a home run as you can get in sports nutrition. Proven to increase muscle size, strength, and stamina.

BioFit Probiotic

150 Million CFU of high-quality probiotic cultures to aid absorption and support healthy gut flora

How to Take

Method 1: Take 5g (1 scoop) of creatine daily. If you’ve never taken creatine before, this method will gradually increase its level inside your muscles, causing them to increase in size, strength and stamina.

Method 2 is known as “loading.” You start by taking 5g of creatine, four times daily (a total of 20 g), for one week. Following this, you take 5g daily. Because the loading method causes your muscles to accumulate creatine faster, you will also experience benefits faster. Pick whichever method you choose. They both work reliably.

“I love that it is a 2 in 1 product with the probiotic. It dissolves better than just plain Creatine. I put it in with my pre workout on training days and work it in whenever I can on days off.”
