- Typical Dosage Range
- 4–6mg weekly, split into 2 injections (e.g., 2mg Monday, 2mg Thursday)
- 2–4mg weekly or biweekly as single injection
- Unreconstituted: store at −20°C; reconstituted: 2–8°C, use within 28 days
- Higher loading doses establish tissue saturation; maintenance sustains effects without receptor downregulation risk
- Injection Frequency
- Twice weekly (every 3–4 days) to maintain plasma levels above threshold
- Once weekly or biweekly depending on response and research timeline
- Avoid freeze-thaw cycles. Aliquot if necessary before freezing
- Frequent early dosing compensates for short 10-hour circulating half-life
- Reconstitution Volume
- 2mL bacteriostatic water per 5mg vial = 2.5mg/mL concentration
- Same. Consistency in concentration prevents dosing errors
- Inject bacteriostatic water slowly down vial wall, never shake, swirl gently until dissolved
- Correct dilution math is non-negotiable. Errors here mean wasted peptide or ineffective dosing
- Injection Route
- Subcutaneous (abdominal, deltoid, or near injury site if localized study)
- Subcutaneous, systemic sites preferred for maintenance
- Rotate injection sites to prevent lipohypertrophy or tissue irritation
- Subcutaneous absorption reaches peak plasma in 30–60 minutes; IM offers no advantage
- Temperature Control
- Ship with cold packs; transfer to freezer immediately upon receipt
- After reconstitution, refrigerate. Never refreeze
- Any excursion above 8°C risks denaturation; visual clarity is not a potency indicator
- Temperature discipline matters more than dosage precision. Heat-damaged TB-4 is biologically inactive
- Contamination Risk
- Use sterile technique. Alcohol swabs, clean work surface, no touch transfer
- Always use fresh needle for drawing and separate needle for injection
- Bacteriostatic water inhibits bacterial growth but does not sterilize; aseptic technique required
- Contaminated vials can cause injection site reactions or systemic infection
