Healing & Recovery Protocol

Thymosin Beta-4Complete Dosing & Administration Guide

The body's natural healing peptide that accelerates tissue repair and reduces inflammation

Dose Range

2-5mg

Frequency

Twice weekly

Route

Subcutaneous injection

Cycle Length

8-12 weeks

Dosing

How much
do I take?

Timing

Best time to take

Morning or evening (flexible)

With food?

Not affected by food intake

If stacking

Best administered on different days than other injectable peptides to minimize injection site stress

Adjusting Your Dose

Increase if

  • +Healing is slower than expected after 3-4 weeks
  • +Inflammation remains high despite initial treatment
  • +Underlying injury is more severe than initially assessed

Decrease if

  • -Injection site reactions become bothersome
  • -Excessive bruising or swelling develops
  • -Systemic sensitivity symptoms appear

Signs of right dose

  • Visible improvement in wound appearance by week 2-3
  • Reduced pain and inflammation
  • Improved range of motion around injured area
  • Faster scar maturation

Administration

How do I
use it?

Reconstitution

What you need

  • Bacteriostatic water or normal saline
  • Sterile syringe (3-5 mL recommended)
  • Sterile needle (25-27 gauge)
  • Alcohol swabs
  • Vial of Thymosin Beta-4 powder

Example

For a 5 mg vial: Add 5 mL bacteriostatic water = 1 mg/mL solution. Each 0.1 mL = 0.1 mg (100 mcg)

Desired dose (mg) × mL per mg concentration = volume to inject. Example: 2 mg dose from 1 mg/mL solution = 2 mL

Injection

Route

Subcutaneous

Best sites

  • Lower abdomen (spare 2 inches around navel)
  • Outer thigh
  • Upper arm (back of triceps)
  • Rotate sites with each injection

Technique

  • 1.Clean skin with alcohol swab and let dry
  • 2.Pinch skin gently to create subcutaneous fold
  • 3.Insert needle at 45-90 degree angle
  • 4.Inject slowly over 2-3 seconds
  • 5.Withdraw needle and apply light pressure
  • 6.Rotate injection sites to prevent lipohypertrophy
Full Injection Guide

Storage

Before reconstitution

Keep in original vial at 2-8°C. Protect from light and freezing. Stable for 36+ months when properly stored

After reconstitution

Store at 2-8°C in refrigerator. Do not freeze reconstituted solution

Signs of degradation

  • Cloudiness or particles in solution
  • Discoloration (should be clear to slightly yellow)
  • Unusual odor
  • Solution has been at room temperature for >4 hours

Sample Daily Schedule

Monday morning

2-5 mg injection

Site: Lower abdomen or outer thigh

First dose of the week (loading phase)

Thursday morning

2-5 mg injection

Site: Opposite thigh or upper arm

Second dose of the week (loading phase, then transition to maintenance)

Weekly (maintenance)

2 mg injection

Site: Rotate between abdomen, thighs, and arms

After 4-6 week loading phase, reduce to once weekly for maintenance

Safety

Is it
safe?

Safety Profile

Thymosin Beta-4 is a naturally occurring peptide found in all cells and body fluids in the human body. Clinical trials have demonstrated excellent safety even at very high doses. IV studies showed doses up to 1260 mg were well tolerated with no serious adverse events.

Multiple Phase 1, Phase 2, and Phase 3 clinical trials completed. Phase 1 study showed dose-proportional pharmacokinetics with increasing half-life at higher doses, indicating predictable and safe dosing.

Common Side Effects

Experienced by some users

Injection site redness

Mild redness at the site of injection, usually resolves within hours to a few days

Management: Ice pack immediately after injection, rotate injection sites, use proper sterile technique

Injection site swelling

Mild swelling or puffiness at injection site, typically mild and temporary

Management: Ice compress for 10-15 minutes after injection, elevate area if applicable

Less Common

  • Temporary mild headache
  • Mild bruising at injection site
  • Transient fatigue

These typically resolve with continued use or dose adjustment.

Stop and Seek Help If

  • ×Severe allergic reaction or anaphylaxis
  • ×Persistent injection site infection
  • ×Significant systemic adverse effects
  • ×Pregnancy is confirmed
  • ×No improvement in healing after 12 weeks (reassess approach)
  • ×Active systemic infection develops without antibiotic coverage
