Sleep is actually four different problems. Most people treat it like one thing, throw melatonin at it, and wonder why they still wake up wrecked. The first is low growth hormone during sleep. Your body releases most of its GH in the first couple hours of deep sleep, and if that pulse isn't firing right, you're not actually recovering. Ipamorelin works through ghrelin receptor signaling to directly promote slow-wave sleep — a 2002 study in the American Journal of Physiology confirmed this in humans. Second is the racing mind. Brain won't stop, you just can't fall asleep. DSIP (delta sleep-inducing peptide) is what's being researched here. Human trials including a double-blind study in chronic insomniacs showed better sleep efficiency and faster sleep onset. Third is "tired but wired." Completely depleted but can't settle. This usually points to mitochondrial dysfunction. SS-31 targets cardiolipin in the inner mitochondrial membrane — the FDA cleared it for Barth syndrome in 2025 and the fatigue data from those trials was solid. Fourth is broken circadian rhythm. You fall asleep fine but wake up at 3am. Epitalon works on the pineal gland to drive melatonin production through the enzyme pathway. Brunel University London confirmed the telomerase findings independently in 2025. Here's what I see people getting wrong: they buy all four and run them together. You won't know what worked. Most people have one or two dominant patterns. Figure out which one fits you first. Which of the four patterns sounds like you? Drop it below — this community has people who've worked through all of them. *This is Not medical advice, Not your doctor. Please also Do your own research.
