01Mechanism of Action

Parameter
Kisspeptin-10
Pancragen
Primary target
GPR54/Kiss1R on hypothalamic GnRH neuronsRønnekleiv 2026Collado-Sole 2026
Pancreatic acinar and islet cell differentiation pathwaysKhavinson 2013
Pathway
Kisspeptin → GPR54 activation → GnRH neuronal depolarization → Pulsatile GnRH release → Pituitary LH/FSH secretionLages 2026Rønnekleiv 2026
Transcription factor activation → Pdx1/Pax6/Pax4/Ptf1a/Foxa2/NKx2.2 upregulation → Cell differentiationKhavinson 2013
Downstream effect
Pulsatile LH surge, FSH elevation, gonadal steroidogenesis, gametogenesis initiationLages 2026
Enhanced pancreatic beta-cell function, normalized insulin/C-peptide dynamics, improved glucose clearanceGoncharova 2014
Feedback intact?
Yes — integrates estradiol, leptin, and IGF-1 signals to modulate HPG axisSilva 2026Rønnekleiv 2026
Yes — preserves physiological glucose-insulin response
Origin
C-terminal decapeptide of KISS1 gene product; retains full biological activity of longer kisspeptin isoforms
Synthetic tetrapeptide derived from pancreatic tissue extracts (Khavinson bioregulator methodology)

02Dosage Protocols

Parameter
Kisspeptin-10
Pancragen
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.
IntramuscularGoncharova 2015
Evidence basis
Phase 1/2 trials
Non-human primate RCT, in vitro cell cultureGoncharova 2015Khavinson 2013

Organotypic tissue culture, both young and aged rat explants.
Frequency
Once daily for 10 daysGoncharova 2014
Treatment cycle
10-day course, effects persist 3+ weeks post-withdrawalGoncharova 2014
Diabetes model
STZ-induced diabetes (rat)
Evaluated via metabolic markers characterizing apoptosis.

04Side Effects & Safety

05Administration Protocol

Parameter
Kisspeptin-10
Pancragen
1. Reconstitution (if lyophilized)
Reconstitute with sterile water or saline per protocol. Gently swirl — do not shake. Solution should be clear and colorless.
Lyophilised tetrapeptide reconstituted in sterile saline or water per manufacturer protocol. Concentration not specified in literature.
2. Route selection
IV infusion for pulsatile delivery in clinical trials; SQ for outpatient protocols. IV allows precise temporal control of GnRH pulse frequency.
Intramuscular injection. Primate studies used daily IM dosing for 10 consecutive days.Goncharova 2015
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.
No specific timing constraints documented. Administered once daily in primate protocols.
4. Monitoring
Serial LH, FSH, estradiol measurements to confirm HPG axis activation. Ultrasound monitoring for ovarian response in fertility applications.
10-day treatment course. Restorative effects on pancreatic function persist for at least 3 weeks post-discontinuation.Goncharova 2014
5. Storage
Lyophilized: store at 2–8 °C, light-protected. Reconstituted: refrigerate, use within 24–48 hours per protocol.
