Research peptides for sleep researchers in South Africa

Sleep science in South Africa is small, serious and polysomnography-based, with laboratories at a handful of universities and private sleep clinics in Johannesburg and Cape Town. Its peptide literature is older than most people realise, going back to delta sleep-inducing peptide in 1977 and GHRH sleep-lab studies in the early 1990s.

This page reads that literature for a sleep researcher: slow-wave sleep and the GH pulse, the circadian clock and its VIP neurons, pineal peptides and melatonin rhythm, and the unresolved DSIP story. It names the compounds, states what each study measured and how strong it was, and explains sourcing in South Africa. Compounds are supplied for laboratory research only.

What this field's literature looks at

The slow-wave sleep literature is the most rigorous. GHRH administration increased slow-wave sleep in human sleep-lab studies in the early 1990s, establishing the link between the GH pulse and deep sleep that secretagogue research still rests on. Circadian research gives VIP its place: VIP neurons of the suprachiasmatic nucleus synchronise the clock, and mice lacking VIP signalling lose rhythmic sleep-wake timing. NAD+ couples to the clock through SIRT1 and CLOCK in mouse work.

The pineal literature is Russian: Epitalon restored nocturnal melatonin rhythm in clinical gerontology cohorts. The DSIP literature is a case study in how a name outlives its evidence: named for enhancing delta EEG after brain infusion in rabbits, followed by small double-blind insomnia studies in the 1980s, and described as unresolved in a 2006 review. A sleep researcher can read all four strands and grade each on its merits.

  • GHRH and slow-wave sleep in humans
  • The GH pulse and sleep stage
  • Suprachiasmatic VIP neurons
  • NAD+, SIRT1 and the molecular clock
  • Pineal peptides and melatonin rhythm
  • Delta sleep-inducing peptide history

Compounds that recur in this literature

Research context only — what each compound has been studied for in published work, not what it does for anyone. Independently tested by Janoshik Analytical.

CJC-1295 + Ipamorelin

Research vial

GHRH analogue plus secretagogue, the pairing that models the GH pulse. GHRH increased slow-wave sleep in human sleep-lab studies, the foundational finding of this literature.

VIP

Research vial

Vasoactive intestinal peptide, the signal of the suprachiasmatic clock's synchronising neurons. Mice lacking VIP signalling lose rhythmic sleep-wake timing; a circadian research tool first and a gut peptide second.

Epitalon

Research vial

The pineal tetrapeptide studied in Russian clinical cohorts for restoring nocturnal melatonin rhythm in ageing. Human evidence from one tradition.

View product and certificate →

DSIP

Research vial

Delta sleep-inducing peptide: rabbit delta EEG in 1977, small human insomnia studies in the 1980s, a sleep role still called unresolved. The literature's own cautionary tale.

Questions sleep researchers ask

Which sleep peptide has the strongest evidence?

GHRH, for slow-wave sleep in human sleep-lab studies. VIP has strong mouse circadian data. DSIP has the weakest, by the literature's own account.

Is DSIP a sleep aid?

No. Its sleep role is unresolved after fifty years and it is supplied for laboratory research only.

Can a sleep clinic order?

For research purposes, yes, with documentation. Nothing is for patients and we provide no protocols.

What does the certificate state?

Compound identity and HPLC purity on an independent Janoshik Analytical report.
