bcaa and eaas
 

Use of free-form amino acids such as BCAA’s and EAA’s would be the preferred choice pre-workout, as well as what could be considered the next generation of proteins, in the form of hydrolysed proteins (such as hydrolysed whey and hydrolysed casein). These protein sources containing mostly di- and tri-peptides are considered to be absorbed much faster than intact proteins and even free-form amino acids, and have been demonstrated to induce greater insulin responses, as well as enhanced amino acid availability when consumed pre-exercise.
