DUSK
What connects stress, our internal clock and the way we rest? A personal question became a closer look at peptide research.
Five separate research products. 3-packs save 15%; 5-packs save 20%.
Laboratory research only · not for human use.

A note from Lutho / Founder
“I started paying closer attention to my sleep. Over three months of personal tracking, I found myself asking what happens before the night begins — and how daytime stress follows us into it.”
That curiosity became DUSK: a collection shaped by reading about circadian rhythms, stress signalling and neural resilience.
“My hypothesis centres on the transition into sleep. Could that window help us understand what follows? It is a question I’m exploring, not a result I can promise.”
Lutho Founder, Peptide South Africa
Start with what is known
The original DUSK idea brings together Epithalon, Pinealon and Selank. Their individual studies do not validate a combined sleep protocol.
The internal-clock question
In older rhesus monkeys, researchers reported changes in evening melatonin and cortisol rhythms. That does not demonstrate better sleep in people.
Read the original studyThe stress-response question
A small study of 62 patients compared Selank with medazepam for anxiety symptoms. It was not a trial of DUSK or proof of improved sleep architecture.
Read the original studyThe neural-resilience question
Laboratory work explores oxidative stress and cell survival. Direct evidence for sleep improvement remains limited; a melatonin-support claim is not established by this study.

The supplied charts document an exploratory model. Their dose, half-life, route and cycle details are unverified and should not be followed as instructions.
The founder’s comparison of three compounds. Half-lives, dose ranges and timing in this chart have not been independently validated for these products or for human use.
Peptides are short chains of amino acids. Researchers investigate how particular chains interact with biological signals. Begin with the compound identity, the study model and the limits of the evidence. A promising laboratory result is not a proven benefit in a person.
No. DUSK is a collection of five separately sold research products. Epithalon, Pinealon and Selank appear in the founder’s blend hypothesis; Semax and Cerebrolysin extend the research collection. Ordering from this page does not create a premixed blend or a validated protocol.
No clinical validation is presented for this combination, ratio, timing or cycle. The founder’s personal observations cannot establish cause and effect, safety or effectiveness. No underlying personal sleep dataset is published on this page.
These listings are for lawful laboratory research only, not human use or consumption. They are not offered as sleep or anxiety treatments. Persistent sleep or anxiety symptoms should be discussed with a qualified healthcare professional.
The single-vial base price is shown for each compound. The recommended 3-pack saves 15%; a 5-pack saves 20%. Pack totals use the same whole-rand rounding as the rest of our store. Each vial contains the stated strength; pack size changes the number of vials, not their strength. BAC water is sold separately. Delivery is R89 below R1,500, with free delivery on merchandise totals of R1,500 or more after discounts and paid add-ons.
Matching-strength analytical documentation for these new listings is pending. No purity, sterility or clinical-equivalence claim is made here. Review each product record and ask us about identity and batch documentation before ordering.
