Epithalon (10 mg Vial) Dosage Protocol

Dosing & Reconstitution Overview

Epithalon (also written Epitalon, the synthetic Ala-Glu-Asp-Gly tetrapeptide) is a short peptide modelled on the natural pineal extract epithalamin and studied for telomerase activation and circadian regulation. The figures below are compiled strictly for laboratory and educational reference — they describe how the compound was handled and dosed across published research, not a recommendation for use in humans or animals.

For a 10 mg vial, adding 2.0 mL of bacteriostatic water yields a concentration of 5 mg/mL (5,000 mcg/mL). At that fill, every 0.01 mL drawn on a U-100 insulin syringe equals 1 unit and delivers 50 mcg, so a full 1.00 mL (100 units) supplies one 5 mg dose and empties the vial in two daily draws.

Standard (Daily Cycle) Dosing Schedule

Unlike weekly metabolic peptides, Epithalon is dosed daily inside discrete cycles. The standard schedule mirrors the most frequently cited protocol: a fixed daily amount held flat across a 20-day course, then a long washout before any repeat course.

Reconstitution Steps

1. Let the sealed lyophilized vial and the bacteriostatic water reach room temperature, then wipe both stoppers with an alcohol swab.
2. Draw 2.0 mL of bacteriostatic water and inject it slowly down the inside wall of the vial — never directly onto the powder pellet.
3. Swirl or roll gently until fully dissolved. Do not shake; vigorous agitation foams the solution and can shear the peptide.
4. The solution should be clear and colourless. Label the vial with the concentration (5 mg/mL) and the reconstitution date.
5. Refrigerate at 2–8 °C, protected from light, and draw subsequent volumes with a fresh sterile syringe each time.

Advanced (Short High-Dose Cycle) Schedule

The advanced schedule compresses the course into a shorter, higher-dose window — 10 mg per day across 10 days for a 100 mg total cycle. It reaches the same cumulative exposure as the standard 20-day course but front-loads it, which raises the per-injection volume to two full draws.

Supplies Needed

• Epithalon vials (10 mg): ~10 vials for one standard 20-day course at 5 mg/day; ~10 vials for a 10-day course at 10 mg/day; ~20 vials for two cycles in a year.
• Insulin syringes (U-100, 1 mL): 20 for a 20-day course (one fresh syringe per day); 20 for a 10-day course at 10 mg (two draws per day).
• Bacteriostatic water (10 mL): two bottles (20 mL) cover one full 10-vial course.
• Alcohol swabs: a single 100-count box comfortably covers a full cycle.

Protocol Overview

• Research goal: model telomerase activation, telomere maintenance and pineal/circadian regulation.
• Schedule: daily subcutaneous administration in short cycles, not continuous use.
• Dose band: 5 mg/day for 20 days, or 10 mg/day for 10 days.
• Fill: 10 mg lyophilized, reconstituted to 5 mg/mL with 2 mL diluent.
• Storage: −20 °C dry long-term; 2–8 °C once reconstituted.

Dosing Protocol Notes

• Hold the daily amount flat across the cycle — Epithalon is not titrated upward like incretin peptides.
• Keep the same daily time, commonly toward evening, for steady circadian modelling.
• Observe the long off-period between courses; the published model is cyclical, typically two courses per year.
• The reconstituted vial empties quickly at these volumes, so plan diluent and vial counts for the full course in advance.

Storage Instructions

Keep sealed lyophilized vials at −20 °C, protected from light, for long-term stability; routine short-term storage at 2–8 °C is acceptable. Once reconstituted, refrigerate at 2–8 °C and use within about two to four weeks. Allow vials to reach room temperature before opening, avoid repeated freeze-thaw cycles, and keep solution out of direct light.

Important Handling Notes

• Use a sterile syringe for every draw and never re-enter the vial with a used needle.
• Vary handling technique to keep the stopper intact across many daily draws.
• Split larger volumes (e.g. the 2.00 mL advanced dose) across two draws if a single syringe cannot hold it.
• Document each draw — date, volume, remaining material — for reproducibility.

How Epithalon Works

Epithalon is a four-residue peptide (Ala-Glu-Asp-Gly) that has been reported to upregulate telomerase activity, supporting telomere elongation in cultured human somatic cells and, in some studies, pushing cells past their normal replicative (Hayflick) limit. It is also linked to restored nocturnal melatonin output from the pineal gland, which underlies its proposed role in circadian regulation. Additional reported activity includes antioxidant effects and immune modulation. Its small size and short sequence give it a brief half-life, which is consistent with the daily-dosing cyclical model used in the literature.

Reported Benefits & Side Effects

Benefits observed in studies

• Telomerase upregulation and telomere maintenance in cultured human cells.
• Restored melatonin secretion and improved circadian rhythm in senescent animal models.
• Extended lifespan and reduced spontaneous tumour incidence in rodent studies.
• Improved cardiovascular and mortality outcomes over a long-term (12-year) human follow-up.

Side effects reported

• Generally well tolerated with no serious adverse events documented in the cited work.
• Occasional mild injection-site reactions.
• Possible transient shifts in sleep pattern, consistent with its melatonin-linked activity.

Injection Technique (Reference Only)

• Prepare the vial stopper and site with alcohol swabs and let them dry.
• Pinch a skinfold and insert subcutaneously at a 45–90° angle depending on needle length; aspiration is not required for subcutaneous work.
• Inject slowly and steadily; split volume across sites when it exceeds a comfortable single injection.
• Rotate sites systematically (abdomen, thigh, upper arm) and dispose of sharps in an approved container. Evening administration is commonly used in the protocol.
