Even after a super hard workout, the body’s baseline testosterone level doesn’t stay high the next day — it goes back to normal quickly.

Scientific Claim

In strength-trained men, a single session of hypertrophic resistance exercise does not alter basal serum testosterone concentrations over a 48-hour recovery period, indicating that acute hormonal responses are transient and do not persist into recovery.

Original Statement

“Basal T concentrations (from 23.8 ± 7.4 to 23.1 ± 7.4 and 22.2 ± 9.1 nmol·L−1 at pre, +24 and +48 hours, respectively) and FT concentrations... remained unaltered compared to the control day values.”

Assessment Explanation

The claim accurately reports the absence of change in basal levels with precise values and time points, avoiding causal language. The design supports this descriptive quantitative claim.

After a tough workout, testosterone spikes briefly but goes back to normal within two days — so the body doesn’t stay in a high-testosterone state long-term.

Similar Assertions

During a tough leg workout, testosterone levels spike temporarily, but they go back to normal by the next day and don’t stay high.

87%

One workout, whether heavy or high-rep, doesn’t change your testosterone levels in the hours after.

84%

Even though short rests make your body release more hormones like testosterone right after lifting, that doesn’t help you build more muscle — longer rests work just as well or better.

77%

Even though the guys doing the most workouts looked like they might have grown a little more, the difference wasn’t big enough to say for sure that more sets = more muscle.

72%

When trained guys do lots of reps, they feel more tired, weaker longer, and more stressed than when they do fewer heavy reps — even though their muscles are damaged about the same.
