TB-500 is the most popular systemic healing peptide in the research community, with 500+ forum threads and a 4.1/5 sentiment score. Backed by strong preclinical wound-healing data but zero completed human trials for the fragment itself. Inject anywhere; it reaches the injury regardless of site.

| Beginner | 2mg | 2x/week |
| Moderate | 2.5mg | 2x/week |
| Aggressive | 5mg | 2x/week |
All TB-500 dosing is community-driven. No human dose-finding study exists for the fragment. Beginner: 2000 mcg (2 mg) twice weekly. Moderate: 5000 mcg (5 mg) twice weekly. Aggressive: 7500 mcg (7.5 mg) twice weekly. Reconstitution math for a 5 mg vial with 1 mL bacteriostatic water: concentration is 5000 mcg per mL. Each 10 units on a 100-unit insulin syringe equals 500 mcg. So 2000 mcg (beginner dose) is 40 units. For a 10 mg vial with 1 mL BAC water: 10,000 mcg per mL, meaning 20 units for 2000 mcg. The loading phase matters more than anything else. Skipping it is the single most common reason for disappointing results. You need 2 injections per week for at least 4 to 6 weeks to build adequate tissue-level concentrations. Going straight to once-weekly maintenance is an underdose. Don't train through the injury during a TB-500 protocol. The community figured this out quickly: TB-500 accelerates repair, but it doesn't protect against re-injury from continued loading of the damaged tissue. Relative rest of the injured structure speeds outcomes. Injection site does not need to be near the injury. Abdomen or thigh, alternating sides.
