Parameter

Kisspeptin-10

N-Acetyl Epitalon Amidate

Primary target

GPR54/Kiss1R on hypothalamic GnRH neuronsRønnekleiv 2026 Collado-Sole 2026

DNA promoter regions (telomerase, RNA polymerase II, retinal genes)

Pathway

Kisspeptin → GPR54 activation → GnRH neuronal depolarization → Pulsatile GnRH release → Pituitary LH/FSH secretionLages 2026 Rønnekleiv 2026

Peptide → DNA complementary binding → Gene transcription initiation → Telomerase catalytic subunit expression

Downstream effect

Pulsatile LH surge, FSH elevation, gonadal steroidogenesis, gametogenesis initiationLages 2026

Telomerase enzymatic activity induction, telomere elongation to early-passage length, extension of replicative lifespan in human somatic cellsKhavinson 2003 Khavinson 2004

Feedback intact?

Yes — integrates estradiol, leptin, and IGF-1 signals to modulate HPG axisSilva 2026 Rønnekleiv 2026

Origin

C-terminal decapeptide of KISS1 gene product; retains full biological activity of longer kisspeptin isoforms

Synthetic tetrapeptide (Ala-Glu-Asp-Gly) derived from pineal extract bioregulator research; N-acetyl and C-amide modifications enhance plasma stability

02Dosage Protocols

Parameter

Kisspeptin-10

N-Acetyl Epitalon Amidate

Clinical trial dose

Phase 1/2 investigational

Dosing protocols vary by indication (hypothalamic amenorrhea, IVF trigger).

—

Route

IV or SQ administration

IV preferred in controlled trials for precise pulsatile delivery.

—

Evidence basis

Phase 1/2 trials

In vitro human cell cultureKhavinson 2004 Khavinson 2003

Half-life

Short (minutes)

Rapid clearance; pulsatile dosing mimics physiological GnRH pulse frequency.

—

Standard dose

—

No standardized human dosing in indexed literature

In vitro protocols use direct culture addition; human clinical dosing protocols are in Russian-language literature outside PubMed scope.

Frequency

—

Not specified in candidate papers

Cell culture protocol

—

Addition to human fetal fibroblast culture induced telomerase activity and telomere elongation to early-passage lengthKhavinson 2004

Cells made 10 extra divisions (44 passages total vs 34 in control).

Duration

—

Chronic treatment in aging culture

Sustained effect through late passages.

Modification stability

—

N-acetyl + C-amide caps enhance peptidase resistance

Standard strategy for tetrapeptide stabilization; specifics not quantified in candidates.

Absolute Contraindications

Kisspeptin-10

·Active pregnancy
·Hormone-sensitive malignancy (breast, ovarian, endometrial)

N-Acetyl Epitalon Amidate

·Active malignancy or history of cancer — telomerase reactivation may promote tumor cell immortalization

Relative Contraindications

Kisspeptin-10

·Polycystic ovary syndrome (PCOS) without monitoring
·Uncontrolled thyroid dysfunction

N-Acetyl Epitalon Amidate

·Individuals with hereditary cancer syndromes or high genetic cancer risk

05Administration Protocol

Parameter

Kisspeptin-10

N-Acetyl Epitalon Amidate

1. Reconstitution (if lyophilized)

Reconstitute with sterile water or saline per protocol. Gently swirl — do not shake. Solution should be clear and colorless.

Subcutaneous injection assumed based on peptide class; no specific protocol in candidate papers.

2. Route selection

IV infusion for pulsatile delivery in clinical trials; SQ for outpatient protocols. IV allows precise temporal control of GnRH pulse frequency.

Standard bacteriostatic water for lyophilized peptides. Exact volume not specified in indexed literature.

3. Timing

Pulsatile dosing (e.g., every 60–90 min) mimics physiological GnRH pulse generator. Single-bolus protocols used for LH surge induction in fertility research.

Lyophilized: -20 °C, desiccated. Reconstituted: refrigerate 2–8 °C. N-acetyl and C-amide modifications improve stability vs unprotected tetrapeptide.

4. Monitoring

Serial LH, FSH, estradiol measurements to confirm HPG axis activation. Ultrasound monitoring for ovarian response in fertility applications.

Human dosing schedules published in Russian-language clinical literature; not indexed in PubMed candidate set.

5. Storage

Lyophilized: store at 2–8 °C, light-protected. Reconstituted: refrigerate, use within 24–48 hours per protocol.

— no documented stacks

N-Acetyl Epitalon Amidate

+ Thymalin

Moderate

View Thymalin →

Both are Khavinson-school bioregulators with epigenetic mechanisms. Thymalin targets thymic transcription factors for immune function, while Epitalon targets telomerase and pineal-axis genes. Combined use theoretically addresses dual axes of aging: replicative senescence and immune decline. Multi-target bioregulator strategy per Khavinson gerontology framework.

Epitalon: Protocol not defined in indexed literature
Thymalin: Tissue-specific bioregulator · separate dosing
Rationale: Complementary transcriptional targets
Primary benefit: Dual-axis aging intervention: cellular senescence + immune restoration
