Total Testosterone stayed above starting levels 15 minutes after top-half reps, but not full reps, in 10 young men. The study compared two forms of Strength Training. It tracked Total Testosterone in men with no training experience. Their average age was about 24. Each man completed three sessions, spaced one week apart: full reps, top-half reps, and rest. The exercise sessions involved back squats and bench presses. The men performed three sets using the heaviest load they could lift 10 times. Full reps covered the whole movement. Top-half reps covered only the upper half of each lift. Blood was taken before exercise, right afterward, and 15 minutes later. Both types of reps raised Total Testosterone right after exercise. After full reps, it returned to starting levels by 15 minutes. After top-half reps, it was still higher than before exercise. The source summary does not give the size of either rise. This was a short-term change, not proof of a lasting boost. The final blood sample came just 15 minutes after exercise. The study does not show whether top-half reps raise resting levels over weeks. It also does not establish better muscle growth or results for experienced lifters. For BioSocial members, the useful takeaway is context for each blood result. A workout log can sit alongside uploaded bloodwork. Noting the exercises, rep style, and time since lifting may help explain differences. Comparing those details with community peers is more useful than treating one higher reading as lasting progress.
