EIGHTY:20 Protein by BuildFastFormula

Eighty:20 inhibits muscle protein breakdown (MPB), stimulates muscle protein synthesis (MPS) for six hours, and tastes great! 

Eighty:20 contains a ratio of micellar casein (80%) to whey (20%) naturall found in milk. The blend of anti-catabolic slow absorbing protein (micellar casein) and anabolic fast absorbing protein (whey) was specifically formulated by reviewing new emerging and historic protein research for advanced lean muscle support.


The combination of micellar casein and whey stimulates muscle protein synthesis (MPS) for six hours, inhibits muscle protein breakdown (MPB), and has been scientifically proven to have greater nitrogen retention than whey or micellar casein alone.



It’s a common misconception fueled by product marketing that whey should only be consumed post workout and micellar casein only around bedtime. It is important to understand that this is not an accurate representation of the facts.


Research has proven that adding micellar casein to whey will not inhibit the fast absorption of whey or the desirable slow absorption of micellar casein.


For example, leucine from whey appears in blood plasma rapidly and is associated with an increase in whole body protein synthesis during the first 180 minutes (anabolic properties) with no significant effect on protein breakdown.


To complement whey protein, micellar casein results in a slower leucine appearance in blood plasma sustained over several hours, with smaller increases in whole body protein synthesis and significant and sustained decreases in muscle protein breakdown (anti-catabolic properties). Net whole body leucine is greater after ingesting micellar casein vs. whey.



Simply put, consumed as a blend, micellar casein and whey maintain their unique slow and fast-digesting properties. For advanced lean muscle support, consume a combination of micellar casein and whey rather than either one alone.


Eighty:20 does not contain amino fillers or whey peptides. Whey peptides may sound cutting-edge and exciting, but they are just another amino acid-spiking trick. They artificially manipulate nitrogen protein testing, meaning you get less protein than you paid for. Whey peptides are often incomplete proteins like glutamine peptides, glycine peptides, or a way to disguise low-percentage whey concentrate.


 Eighty:20 is supported by unbiased published scientific data. We encourage everyone to research our claims before purchasing. We believe an educated consumer is a long-term consumer.

Ask a Question
  • Can we see the supplant facts labels and ingredients?

  • I play for the Houston Texans. Is this product NSF certified? Or are there any chance of cross contamination from potentially illegal substances?

    BuildFastFormula is not NSF at this time, but they are working on becoming NSF certified in the future.  However, all of their products are 3rd party tested at an ISO accredited laboratory (International Organization of Standardization).  ISO develops many different standards for a wide range of organizations such as the ISO 9000, which relates to quality management; the ISO 14000, for environmental management; and the ISO 22000, for food safety management, just to name a few. 

    Since BFF products provide fully transparent formulas that are 3rd party tested at an ISO accredited lab, you can be sure what's on the label is exactly in the bottle.
