In mice, serum thymosin alpha‑1 showed a circadian rhythm, peaking 1.5 hr after light onset.
In plain wordsIn mice, the body's own thymosin alpha‑1 level in blood rose and fell over the day, peaking soon after light onset.

Source sentences
Results from the first experiment showed that Tsn-alpha 1 undergoes a circadian rhythm (p less than 0.001) with an acrophase (time of peak levels) 1.5 hr after the onset of light, and an amplitude (amount of maximum variation from the 24-hr mean) of 0.493 ng/ml Tsn-alpha 1-like immunoreactivity.
2 context sentences(design, population, supporting numbers)
In these experiments, groups of 10 C57BL/6 or Swiss Webster mice were sacrificed at 4- or 6-hr intervals over a 24-hr period.
Serum Tsn-alpha 1 and corticosterone levels were determined by radioimmunoassay.
This result measures the body's own Thymosin alpha-1. Nobody was given the peptide. It is not evidence about taking it.
