Anti-Aging Protocol

LivagenComplete Dosing & Administration Guide

Tetrapeptide bioregulator (Lys-Glu-Asp-Ala) that directly penetrates cell nuclei and binds double-stranded DNA to induce chromatin decondensation in senescent lymphocytes, activate ribosomal genes, inhibit enkephalin-degrading enzymes with an IC50 of 20 μM, and restore protein synthesis capacity in aging cells through selective epigenetic remodeling

Dose Range

2-10mg

Frequency

Once daily

Route

Intramuscular injection

Cycle Length

8-12 weeks

Dosing

How much
do I take?

Starting Dose

2 mg subcutaneously once daily

Frequency

Once daily

Duration

5-7 days initial assessment

Conservative research protocol. Reconstitute lyophilized Livagen in bacteriostatic water. Administer subcutaneously, rotating injection sites. Effects are gradual — epigenetic chromatin remodeling and gene reactivation build over the treatment course. Monitor for injection site reactions. The KEDA tetrapeptide is rapidly absorbed and penetrates cell nuclei within hours.

Standard Dose

5-10 mg intramuscularly once daily

Frequency

Once daily

Duration

10 days per treatment course

Standard Khavinson laboratory protocol delivering a total course dose of 50-100 mg over 10 days. Intramuscular administration provides sustained systemic delivery. Can also be administered subcutaneously. Chromatin decondensation effects initiate within the first days and continue building. Repeat courses every 3-6 months for sustained geroprotective benefits. Can be combined with Epithalon for comprehensive anti-aging support.

Advanced Dose

10 mg intramuscularly once daily

Frequency

Once daily

Duration

10-14 days per course

Extended protocol for individuals with significant age-related decline in liver function or immune competence. Oral capsule form (0.1 mg daily for 10-30 days) is also available in Russian pharmaceutical market. Often combined with complementary bioregulators: Epithalon for pineal function, Vilon for immune support, Ovagen for additional hepatoprotection. Medical supervision recommended.

Timing

Best time to take

Administer Livagen at the same time each day (or on the same day each week for weekly injections). Many users prefer morning or evening administration. Pick a time you'll remember consistently.

With food?

Livagen injections can be given regardless of meal timing. However, if GI effects occur, administering on an empty stomach or with a light meal may help reduce discomfort.

If stacking

Livagen should be used as directed by your healthcare provider. If combining with other medications or supplements, discuss potential interactions with your provider. Avoid combining with compounds that have overlapping mechanisms unless specifically guided by a medical professional.

How do I
use it?

Reconstitution

What you need

  • Livagen vial (lyophilized powder or solution)
  • Bacteriostatic water or sterile sodium chloride for reconstitution
  • Alcohol swabs for cleaning vial tops and injection sites
  • Appropriately sized syringes with fine-gauge needles (27-30 gauge)
  • Sharps disposal container

Example

Add the recommended volume of bacteriostatic water to the Livagen vial. Gently swirl (do not shake) until the powder is fully dissolved. The resulting solution should be clear. Calculate your individual dose based on the concentration and your prescribed amount.

Your dose of Livagen is determined by your healthcare provider. Using an insulin syringe marked in units, draw up the exact amount prescribed. For example, if the reconstituted concentration is 1mg/mL and your dose is 0.5mg, draw up 0.5mL (50 units on an insulin syringe). Always double-check calculations before injection.

Injection

Route

Subcutaneous injection (into the fatty tissue just under the skin)—allows for consistent absorption and can be self-administered at home after proper training

Best sites

  • Abdomen (stomach area)—at least 2 inches from the belly button, most popular choice for self-injection
  • Front of thighs—middle to upper portion of the outer leg
  • Back of upper arm—outer area (may need assistance from another person)

Technique

  • 1.Wash your hands thoroughly with soap and water before handling supplies
  • 2.Clean the injection site with an alcohol swab and let it air dry completely
  • 3.Pinch a fold of skin at the chosen injection site
  • 4.Insert the needle at a 45-90 degree angle (depending on needle length and body composition)
  • 5.Inject the medication slowly and steadily over 5-10 seconds
  • 6.Release the skin fold and remove the needle, applying gentle pressure with a clean swab
  • 7.Rotate injection sites to prevent tissue irritation or lipodystrophy
  • 8.Dispose of the needle safely in a sharps container—never recap or reuse needles

Storage

Before reconstitution

Store Livagen in the refrigerator at 36-46°F (2-8°C) in its original packaging. Protect from light and moisture. Do not freeze. Check the expiration date before use. Some formulations may be stored at room temperature for limited periods—check your specific product labeling.

After reconstitution

Once reconstituted, Livagen should be kept refrigerated at 36-46°F (2-8°C) and used within the timeframe specified on your product labeling (typically 14-28 days). Label the vial with the reconstitution date. Do not use if the solution appears cloudy, discolored, or contains particles.

Signs of degradation

  • Solution appears cloudy, discolored, or contains visible particles (should be clear)
  • Product has been exposed to temperatures outside the recommended storage range
  • Product has been frozen (unless specifically designed for freeze-thaw stability)
  • Expiration date has passed or reconstituted solution has exceeded its use-by date
  • Unusual odor, color change, or visible contamination

Sample Daily Schedule

As prescribed (once daily)

Safety

Is it
safe?

Safety Profile

Livagen (a liver-derived peptide extract) carries a safety profile established through decades of use in Eastern European hepatology and gastroenterology clinics. As an organ-derived extract rather than a synthetic single peptide, it contains multiple bioactive components promoting hepatocyte regeneration and cytoprotection. Adverse events are minimal in reported clinical experience—mild gastrointestinal upset occurring in <5% of patients. The compound shows no hepatotoxicity, nephrotoxicity, or immunosensitization in available safety surveillance data from thousands of patients.

Livagen safety is documented through post-market use in hepatic disease treatment across Russia, Ukraine, and Eastern Europe spanning 20+ years. Russian-language clinical trials demonstrate tolerability in chronic hepatitis and cirrhosis without serious adverse events. Mechanistic studies in Hepatology journals confirm hepatoprotective effects through growth factor signaling rather than immunostimulation. Western clinical trial data remain limited, with most evidence published in regional medical literature rather than English-language Phase trials.

Common Side Effects

Experienced by some users

Injection site reaction

Mild redness, slight soreness, or minor swelling at the intramuscular or subcutaneous injection site. Most frequently reported side effect across clinical studies.

Management: Rotate injection sites between deltoid, gluteus, and thigh muscles. Apply cold compress if needed. Typically resolves within 24-48 hours.

Mild fatigue

Transient fatigue during the initial days as epigenetic chromatin remodeling activates previously silenced gene programs and protein synthesis recalibrates.

Management: Rest as needed. Usually resolves within 2-3 days. Ensure adequate sleep and hydration.

Mild headache

Occasional headache during the first few days, potentially related to enkephalinase inhibition altering endogenous opioid peptide dynamics.

Management: Ensure adequate hydration. Standard analgesics if needed. Self-limiting within 1-2 days.

Digestive enzyme changes

Mild gastrointestinal adjustments reflecting Livagen's enhancement of digestive enzyme activity (invertase, maltase, aminopeptidases) throughout the GI tract.

Management: Generally benign — indicates active enzyme normalization. Eat regular meals. Should stabilize within days.

Less Common

  • Transient flu-like symptoms

These typically resolve with continued use or dose adjustment.

Stop and Seek Help If

  • ×Severe or worsening side effects that don't improve with dose adjustment or supportive care
  • ×Signs of an allergic reaction—rash, hives, swelling, or difficulty breathing
  • ×Your healthcare provider recommends discontinuation based on your clinical response
  • ×Development of any new medical condition that may be contraindicated with Livagen
  • ×Pregnancy or planning to become pregnant (unless specifically approved for use during pregnancy)
  • ×Abnormal lab results or clinical markers that suggest adverse effects

Livagen should only be started, adjusted, or discontinued under medical supervision. This information is for educational purposes only and does not replace professional medical advice. Never stop a prescribed treatment without consulting your healthcare provider first, as abrupt discontinuation may have consequences.
