01Mechanism of Action
Parameter
Adamax
Matrixyl
Primary target
Melanocortin receptors (MC-Rs) in hippocampus and cortex
Dermal fibroblastsPaccola 2025
Pathway
ACTH(4-10) fragment → MC-R binding → BDNF/trkB upregulation → neurotrophic signaling
Fibroblast stimulation → Collagen I/III/IV synthesis → Glycosaminoglycan deposition → ECM remodeling
Downstream effect
Increased hippocampal BDNF expression, trkB tyrosine phosphorylation, enhanced conditioned avoidance learning, circadian rhythm normalizationDolotov 2006Arushanian 2008
Enhanced extracellular matrix synthesis, improved dermal density, collagen remodelingPaccola 2025
Origin
ACTH(4-10) fragment with modified amino acid sequence at positions 8, 9, 10Teter 2001
Synthetic pentapeptide KTTKS derived from pro-collagen I fragment, N-palmitoylated for lipophilicityGomes 2022

Parameter
Adamax
Matrixyl
Animal dose (rat)
50 mcg/kg body weightDolotov 2006
Single intranasal application; produced maximal BDNF response.
—
Frequency
Single-dose or chronic administration protocols
Chronic dosing normalized circadian rhythms; single-dose produced acute BDNF elevation.
—
Human dose (exploratory)
Not established — limited human data
ACTH(4-10) and analogs dosed 30–60 mcg intranasally in early human studies.
—
Evidence basis
Animal (rodent, rabbit) studies; minimal human RCT data
—
Timing
Variable — chronic administration for circadian effects
—
Formulation concentration
—
0.5–5% in topical vehicle
Common cosmeceutical range; higher concentrations in clinical formulations.
Application frequency
—
Twice daily (AM/PM)
Standard cosmeceutical protocol.

Absolute Contraindications
Adamax
- ·Pregnancy and lactation (precautionary; no data)
- ·Active cardiovascular instability (due to potential pressor effects)
Matrixyl
- ·Known hypersensitivity to palmitoyl peptides
Relative Contraindications
Adamax
- ·Hypertension (monitor BP if using higher doses)
- ·Renal impairment (natriuretic effects may alter electrolyte balance)
Matrixyl
- ·Active dermatitis or open wounds at application site
05Administration Protocol
Parameter
Adamax
Matrixyl
1. Reconstitution (if lyophilised)
Add sterile water or bacteriostatic water to lyophilised vial per manufacturer guidance. Roll gently — do not shake. Ensure clarity before use.
Wash face with gentle cleanser. Pat dry.
2. Route
Intranasal administration is the primary route in animal and exploratory human studies. Delivered via nasal spray or dropper to ensure mucosal absorption.Dolotov 2006Smolnik 2000
Apply 2–3 drops to fingertips. Massage gently into target areas (face, neck, décolletage). Allow 1–2 minutes for absorption.
3. Timing
Variable. Single-dose protocols for acute cognitive tasks; chronic daily dosing for circadian rhythm normalization and sustained neuroprotection.
Twice daily — morning and evening. Apply before heavier creams or sunscreen.
4. Storage
Lyophilised: room temperature, light-protected. Reconstituted: refrigerate 2–8 °C, use within manufacturer-specified timeframe.
Store at room temperature, away from direct sunlight. Stable in formulation for 12–24 months.
06Stack Synergy
Adamax
+ Semax
ModerateBoth Adamax and Semax are ACTH(4-10)-derived nootropics acting via melanocortin receptors and BDNF upregulation. Adamax has distinct amino acid modifications at positions 8-10, potentially offering complementary receptor binding profiles or metabolic stability. Stacking may amplify neurotrophic signaling and cognitive enhancement, though direct synergy studies are absent. Theoretical multi-pathway benefit.
- Adamax
- Research dose intranasal
- Semax
- 300–600 mcg intranasal
- Frequency
- Once daily, morning or pre-cognitive task
- Primary benefit
- Enhanced BDNF upregulation, cognitive performance, neuroprotection
Matrixyl
+ GHK-Cu
Multi-pathwayMatrixyl (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.
