low protein?

[-BLP-]

a friend of mine a truck driver 41 y.o. , good muscular shape, train all his life , steroid history 8 years or so , did a bloodwork/check , and is protein result was really really low ??? since is a driver , he rely on whey shake for most of time to gain less fat, he stay sit for so long so it make sense , why someone who have 5 to 7 shake's a day will portait this ? he came allergic ? he doesnt seem to loose mass ... is body reject whey isolate ? drug use compromise protein asimilation ?

Is he adding anything (like fat) to the shake to slow down the digestion? The whey is entering too fast for regular meal replacement. If it isn't that I don't know.
