05Administration Protocol

Parameter

Matrixyl

Pinealon

1. Cleanse

Wash face with gentle cleanser. Pat dry.

Add 1–2 mL bacteriostatic water to 10 mg vial.

2. Application

Apply 2–3 drops to fingertips. Massage gently into target areas (face, neck, décolletage). Allow 1–2 minutes for absorption.

SQ — abdomen preferred.

3. Timing

Twice daily — morning and evening. Apply before heavier creams or sunscreen.

Daily during cycle, any time.

4. Storage

Store at room temperature, away from direct sunlight. Stable in formulation for 12–24 months.

Lyophilised: room temp. Reconstituted: refrigerate ≤30 days.

5. Needle

—

29–31G, 4–8 mm insulin syringe.

06Stack Synergy

Matrixyl

+ GHK-Cu

Multi-pathway

View GHK-Cu →

Matrixyl (Pal-KTTKS) stimulates fibroblast collagen synthesis via pro-collagen I mimicry, while GHK-Cu acts as a copper-binding tripeptide that enhances ECM remodeling through metalloproteinase modulation and wound healing pathways. Combined, they address collagen synthesis (Matrixyl) and matrix remodeling/repair (GHK-Cu) through distinct mechanisms, producing complementary effects on dermal architecture.

Matrixyl: 0.5–5% topical serum · AM/PM
GHK-Cu: 1–2% topical serum · same application
Frequency: Twice daily
Primary benefit: Enhanced collagen synthesis + ECM remodeling, improved skin density and elasticity

Pinealon

+ Epitalon

Moderate

View Epitalon →

Pinealon (neuroprotection) + Epitalon (telomerase activation) form the canonical Khavinson "longevity stack" — both pineal-derived bioregulators with complementary axes. Pinealon supports neuronal antioxidant defense; Epitalon supports telomere maintenance. Anecdotally cycled together 1–2× per year.

Pinealon: 5–10 mg SQ · daily × 10 days
Epitalon: 5–10 mg SQ · daily × 10 days (overlap or alternate)
Primary benefit: Neuroprotection + telomere preservation
