PEP-OXYTOCIN • RESEARCH USE ONLY

Oxytocin

Oxytocin, often referred to as the "connection hormone," supports emotional balance, trust, bonding, and social connection while helping reduce stress and anxiety. It plays a key role in emotional intimacy, mood regulation, and relaxation, making it useful for both social and relationship support.

Protocol & Dosing

Use it as needed, typically 30–60 minutes before the desired effect. Do NOT use daily. Most users take it 2–3 times per week, leaving 24–48 hours between doses.

Standard
125 mcg (2 sprays)
Higher
250 mcg (4 sprays)
Key Benefits

Enhances mood, deepens emotional and social connection, reduces anxiety and stress, promotes relaxation, and may support libido and emotional intimacy.

Guidance
  • Start with 2 sprays and assess emotional and relaxation response
  • Increase to 4 sprays only if needed
  • Avoid repeated daily use
  • Best used situationally for connection, relaxation, or stress reduction
  • Ideal for social situations, emotional bonding, or intimacy support
  • Can be combined with PT-141 or Kisspeptin for enhanced libido and connection (use lower doses when stacking)
  • Effects are subtle and emotional rather than stimulant or sedative
PROPRIETARY DELIVERY TECHNOLOGY

Zenith Nano™ Spray System

Nasal delivery is facilitated with the Zenith Nano™ Spray System — a proprietary liquid ion delivery platform engineered for enhanced bioavailability, deep tissue penetration, and improved compound stability without compromising safety. Unlike carriers that rely on encapsulation, it enables direct solubilization and optimized partitioning of actives including peptides and coenzymes — no liposomes, no lipid nanoparticles, no emulsifier-dependent payloads. Built from amino acids and endogenous molecules for biocompatibility; scalable across routes that include intranasal sprays.

Lipid disruption & cation exchange
Alkyl chains intercalate into the stratum corneum lipid matrix via hydrophobic interactions, reducing cohesion and increasing permeability. Cationic components displace native ions such as Ca²⁺ within lipid lamellae, weakening structural integrity so actives pass through more efficiently.
Dual-polarity solubilization
Hydrophilic and lipophilic character solubilizes and transports a broad range of actives directly — without emulsifiers or encapsulating carriers.
Keratin modulation & partitioning
Temporarily denatures keratin within corneocytes, opening transient micro-pathways for epithelial migration. Improves solubility and skin partitioning while maintaining proprietary differentiation for IP — inspired by systems like CAGE (choline–geranic acid ionic liquids).
Superior loading vs. lipid carriers
Solubilizes actives directly instead of inefficient encapsulation. In-house studies: lipid-based carriers penetrated only ~22 μm — insufficient for meaningful absorption — whereas the Zenith Nano™ Spray System reaches therapeutically relevant layers.
>57× vs. saline · <10 nm (DLS)
>57× barrier penetration vs. saline in an ex vivo epithelial model (Zenith Nano™ third-party data). Minimum confirmed nanoparticle size under 10 nm — mucus-penetrating ionic clusters by dynamic light scattering.
Safety, stability & distribution
ISO 10993-5 CCK-8 assay: 80–100% viability at 24 h and 48 h. Four-month room-temperature stability: 101.1–101.9% HPLC recovery — no cold chain. In vivo oral mouse study: systemic distribution across five organs at 1 hour post-dose.
