Sleep Assistance Compounds in Canada | Peptides, Circadian Modulators & GH Secretagogues
Canada Steroid Depot's sleep assistance category covers the most extensively researched non benzodiazepine, non sedative hypnotic compounds for sleep quality improvement, circadian rhythm regulation, and slow wave sleep enhancement. Sleep quality is one of the most impactful variables in recovery, body composition, cognitive function, and hormonal health. With growth hormone secretion, testosterone production, and cortisol regulation all critically dependent on adequate slow wave and REM sleep architecture. CSD stocks the complete range of compounds studied for their sleep enhancing properties across multiple mechanisms.
DSIP | Delta Sleep Inducing Peptide
Delta Sleep Inducing Peptide (DSIP) is a nonapeptide originally isolated from rabbit cerebral venous blood during slow wave sleep induction experiments in the 1970s. It is studied for its ability to increase delta wave (slow wave) sleep. The deepest, most restorative stage of non REM sleep critical for physical recovery, growth hormone secretion, and memory consolidation. Unlike traditional sedative hypnotics, DSIP does not produce sedation or impair next-day cognitive function. It modulates sleep architecture toward deeper slow wave sleep rather than inducing sleep through sedation. DSIP also demonstrates stress protective, antioxidant, and neuroendocrine regulatory properties in research settings. It is administered subcutaneously and is available in CSD's lyophilized vial format.
MK-677 (Ibutamoren) | GH secretagogue with sleep enhancing properties
MK-677 (Ibutamoren) is a potent, orally active growth hormone secretagogue that acts as a ghrelin receptor agonist, stimulating pulsatile GH and IGF-1 secretion. Beyond its anabolic and body composition effects, MK-677 significantly enhances slow wave sleep duration and quality. An effect directly related to the GH pulse it induces during the early sleep cycle. Research demonstrates that MK-677 increases REM sleep duration and improves overall sleep quality, making it one of the most researched compounds for simultaneous body composition and sleep quality optimization. It is taken orally before bed to align the GH pulse with the natural nocturnal GH secretion window.
Circadian rhythm modulators | Epithalon, Agomelatine and Melatonin
Circadian rhythm dysregulation is one of the most common underlying drivers of poor sleep quality. Particularly in shift workers, frequent travelers, and individuals with high evening light exposure. Melatonin is the primary circadian entrainment signal, produced by the pineal gland in response to darkness and suppressed by light exposure. Pharmaceutical grade Melatonin at physiological doses (0.5–3mg) is researched for circadian rhythm resynchronization rather than sedation. Agomelatine is a melatonergic agonist (MT1/MT2) and 5-HT2C antagonist that resynchronizes circadian rhythms while producing antidepressant effects. Particularly relevant where sleep disruption is concurrent with mood disorder. Epithalon is researched for its ability to restore pineal melatonin production in ageing subjects. Addressing age related decline in melatonin secretion as a longevity and sleep quality intervention.
Selank and peptide anxiolytics for sleep onset
Sleep onset difficulty driven by anxiety and hyperarousal is one of the most common research targets in sleep assistance protocols. Selank; a synthetic tuftsin analogue with potent anxiolytic effects is studied for its ability to reduce evening anxiety and hyperarousal without sedation, improving sleep onset latency without impacting sleep architecture or producing next day cognitive impairment. Unlike benzodiazepines, Selank does not suppress REM sleep or slow wave sleep. Making it particularly valuable in research protocols where anxiety driven sleep onset difficulty is the primary target without compromising sleep quality once asleep. Administered intranasally 30–60 minutes before sleep in most research protocols.

DSIP (Delta Sleep Inducing Peptide) is a nonapeptide studied for its ability to increase slow wave (delta wave) sleep. The deepest, most physically restorative sleep stage. Unlike sedative hypnotics, DSIP does not induce sleep through sedation. it modulates sleep architecture toward deeper slow wave sleep without impairing cognitive function or producing next day grogginess. It also demonstrates stress protective and neuroendocrine regulatory properties relevant to recovery and hormonal health.
MK-677 stimulates pulsatile growth hormone secretion through ghrelin receptor agonism. The GH pulse produced by MK-677; particularly when taken before sleep significantly enhances slow wave sleep duration and quality, as slow wave sleep and GH secretion are intrinsically linked. Research demonstrates measurable improvements in REM sleep duration and overall sleep architecture with MK-677 administration, alongside its well documented body composition and recovery benefits.
Melatonin is a circadian entrainment signal that regulates sleep timing. It is best suited to circadian rhythm disorders such as jet lag, shift work, and delayed sleep phase syndrome rather than sleep quality improvement per se. Agomelatine is a melatonergic agonist and 5-HT2C antagonist that both resynchronizes circadian rhythms and improves sleep architecture. Increasing slow wave sleep and REM sleep while simultaneously producing antidepressant effects. Agomelatine is more appropriate where both sleep quality and mood components are research targets.
Yes! Combining compounds that address different aspects of sleep through complementary mechanisms is a common research approach. A typical combination protocol might include DSIP for slow wave sleep enhancement, Selank for anxiety driven sleep onset improvement, and MK-677 for GH pulse augmentation and overall sleep architecture improvement. Epithalon may be added to restore age related melatonin decline as a longer term circadian support intervention.
