However, a randomized double-blind trial in men found no change in testosterone levels with its use

The current evidence base primarily from animal studies and limited human trials suggests the following potential applications: Improved sleep quality increased proportion of slow-wave sleep, reduced sleep latency, fewer nocturnal cortisol spikes Cortisol normalisation reduced HPA hyperactivation, particularly relevant in high-stress or metabolically burdened patients Nociceptive effects several studies indicate DSIP modulates pain processing, with implications for patients whose poor sleep is pain-driven (3) Antioxidant activity may reduce oxidative stress markers, which are elevated in both sleep-deprived and insulin-resistant individuals Neuroendocrine support preliminary evidence of effects on LH, FSH, and somatostatin hormones that regulate testosterone, oestrogen, and growth hormone release Potential stress adaptation some data suggest DSIP may reduce the physiological stress response magnitude without blunting alertness It is important to be precise here

Other benefits, such as improved sleep quality, enhanced mood, or cognitive improvements, may develop more gradually over several days or weeks of treatment
The symptoms are more common at the start of treatment
