01Mechanism of Action

Parameter

Epitalon

SNAP-8

Primary target

Telomerase activity (proposed); pineal melatonin axis modulationKhavinson 2003

SNARE complex (SNAP-25 competitive binding site)

Pathway

Activation of telomerase reverse transcriptase (hTERT) in somatic cells; pineal-axis modulation supports endogenous melatoninKhavinson 2003

Acetyl octapeptide-3 → SNARE complex disruption → Reduced vesicular fusion → Decreased acetylcholine release → Muscle relaxation

Downstream effect

Telomere elongation, improved sleep architecture, reported lifespan extension in aged miceKhavinson 2003

Transient reduction in neuromuscular signal transmission, decreased muscle contraction amplitude, wrinkle depth reduction

Feedback intact?

—

N/A — topical cosmetic, no systemic endocrine axis

Origin

Synthetic 4-AA peptide derived from epithalamin (a natural pineal extract)Khavinson 2003

Synthetic peptide derived from N-terminal fragment of SNAP-25 protein (synaptosomal-associated protein 25 kDa)

Antibody formation

Not reported

—

Cytotoxicity

—

Concentration-dependent antiproliferative effect observed in vitro; IC50 ~10 mg/mL (argireline, 6-AA analogue)

Commercial formulations typically use 0.05–0.1 mg/mL, well below cytotoxic threshold.

Skin irritation

—

Minimal; well-tolerated in clinical use

Peptide oxidation

—

Methionine residue susceptible to oxidation in formulation; may reduce efficacyKluczyk 2021

Formulation stability issue, not a direct adverse effect.

Systemic absorption

—

Negligible; peptide remains in stratum corneum and epidermisKraeling 2015

Hypersensitivity

—

Rare; no widespread allergic reactions reported

Absolute Contraindications

Epitalon

·Pregnancy / breastfeeding
·Active malignancy or pre-malignant state

SNAP-8

·Known hypersensitivity to acetyl octapeptide-3 or formulation excipients

Relative Contraindications

Epitalon

·Family history of cancer

SNAP-8

·Active skin infections or open wounds at application site
·Neuromuscular disorders (theoretical concern, no documented cases)

05Administration Protocol

Parameter

Epitalon

SNAP-8

1. Reconstitution

Add 1–2 mL bacteriostatic water to 10 mg vial → 5–10 mg/mL.

Wash face with gentle cleanser and pat dry. Remove makeup and surface oils to optimize peptide contact.

2. Injection site

SQ — abdomen preferred. Rotate sites.

Apply 1–2 drops or pea-sized amount of SNAP-8 serum or cream to target areas (forehead, glabellar lines, crow's feet). Gently massage until absorbed.

3. Timing

Pre-sleep preferred to align with pineal axis.

Twice daily — morning and evening. Allow 2–3 minutes for absorption before applying additional skincare products.

4. Storage

Lyophilised: room temp, light-protected. Reconstituted: refrigerate ≤30 days.

Apply before heavier creams or occlusive moisturizers. Peptides penetrate best from water-based serums on clean skin.

5. Needle

29–31G, 4–8 mm insulin syringe.

Store at room temperature, away from direct sunlight. Refrigeration may extend shelf life of formulations containing unstable peptides.

6. Duration

—

Consistent use for 20–60 days required for visible wrinkle reduction. Effects are temporary and reverse upon discontinuation.
