For rats, the best time for muscle protein building after eating regular whey protein is about an hour later.

Scientific Claim

In rats, the peak muscle protein synthesis rate after intact whey protein ingestion occurred 60 minutes post-administration.

Original Statement

“Postprandial FSR was highest 60 min after WPC was administered (3.64 ±0.19, 4.62 ±0.28, 4.19 ±0.21 and 3.99 ±0.19%/day for 30, 60, 90 and 120 min).”

Similar Assertions

When rats exercised and then ate a small amount of whey protein hydrolysate, their muscles built protein faster than when they ate regular whey protein at the same dose.

84%

When rats swam for two hours and then consumed whey protein, their muscle building rate peaked at 60 minutes with a value of 7.76% per day.

75%

Eating a big protein meal (100g) after working out makes your muscles keep building for longer than a smaller meal (25g), at least for 12 hours.

74%

A larger dose of regular whey protein activated a key muscle-building pathway more than hydrolyzed whey protein or no protein in rats.

73%

When rats swam for two hours and consumed dairy proteins (whey, milk, or caseinate), their muscle building rates were higher than those eating soy protein at specific times after eating.
