Watched an Interview with an accomplished german amater BB these days who considers himself as a supplement "guru" for many years.
The guy claimed that Whey Protein is still the "gold standard" for all proten powders. The biggest BS scam product to steal money from clueless idiots nowadays is the trendy "Beef Protein".
If the powder sold in tubes was legit protein extracted from lean quality beef
a) one tube wouldn't cost 40 bucks but rather several 100s of dollars (not affordable for average Joe)
b) the protein would taste so bad that you'd puke after every single sip.
What's sold as "Beef Protein" in tubes is pure garbage, collagenic protein and slaughterhouse waste with no biological value what-so-ever.
Is that true? Has Kai lied to us?
