Look at your goal and needs and training/recovery requirements.
When riding hard I usually use 1.2 x body weight in kg = in grams 102g for me.
When I did bodybuilding I using 150g of protein and creatine etc.
Funnily enough attended a lecture yesterday about sport stimulants and growth factors. Amazing what pro atheletes/sports scientists are applying.
Promax is whey isolate-easily absorbed/digested.
Everybody's body is different. I'm slightly lactose intolerant and stay away from wheat.
For cycling I find just buying chicken/fish and the odd recovery shake made by sis adequate for cycling.
Find out what you are consuming to nearest gram before adding loads.
Also I take a protein shake before bedtime as Growth hormone is higher at night and help recovery.
If you're not training hard then you can just eat healthy and sorted.
