The Claim
After whey peptide ingestion, the phosphorylation of S6K1 at Thr389 is significantly higher in healthy young women than in healthy young men, despite identical dosing and comparable baseline phosphorylation levels.
What the research says
Supports is higher
Support is ahead, but a single strong opposing study can change this.
These are independent scores, not a percentage. Higher-grade studies count more, so a single strong opposing study can outweigh several weaker ones.
After consuming whey peptides, healthy young women show a higher level of S6K1 protein phosphorylation at Thr389 than healthy young men, even when both groups receive the same dose and start with the same baseline phosphorylation.
See the scientific wording
The phosphorylation of S6K1 at Thr389 after whey peptide ingestion is significantly higher in healthy young women than in healthy young men, despite similar baseline levels and identical dosing.
After consuming whey peptides, amino acids enter the bloodstream and are taken up by muscle cells, where they activate a molecular switch that turns on protein-building machinery. This switch triggers a chain reaction that ultimately phosphorylates S6K1 at Thr389, and this response is stronger in women than in men, even when both consume the same amount.
What the research says
1 studyWhen men and women drank the same amount of whey peptide, women’s muscles showed twice as much activation of a key signal that helps build muscle, even though both started at the same level. So yes, women’s muscles responded more strongly.
