What it is
TB-500 is a synthetic fragment of thymosin β-4. used for tendon/ligament/muscle recovery sits in the connective-tissue repair class, where research has focused on tendon, ligament, gut, and systemic healing responses. Pepture treats TB-500 purely as a tracking target, meaning the app records what you enter without making any clinical recommendation about whether the compound is right for you. That determination belongs with a licensed clinician who knows your full history.
Most research and practitioner use reports subcutaneous (SubQ) injection with a U-100 insulin syringe. Its half-life of roughly 3 days places it in the long-acting class, with once-weekly or once-monthly dosing patterns reported.
The Pepture library entry for TB-500 exists so that if you are already logging a TB-500 protocol, you can do so with structured fields, cycle calendars, injection-site rotation, and biomarker context rather than a loose notebook. If you are considering starting a protocol with TB-500, speak with a licensed clinician before obtaining or dosing the compound.
Common uses
The uses most commonly logged for TB-500 in the Pepture community align with its recovery positioning. Users track TB-500 alongside range-of-motion ratings, injection-site heatmap, and subjective recovery scores, so the protocol's impact can be evaluated over a full cycle rather than by memory.
Typical logged doses in Pepture sit in the 2 mg to 2.5 mg range; individual protocols vary substantially.
Pepture makes no claim about efficacy. TB-500 is either FDA-approved, used under a prescription, or labelled for research only depending on the jurisdiction. Confirm the legal and clinical status of TB-500 in your country with a licensed clinician before use.
Reconstitution math
Open the pre-filled TB-500 reconstitution calculator to compute syringe units per dose.
Reconstitution guidance
Typical vial size 5 mg. Reconstitute with 2 mL bacteriostatic water. Refrigerate after reconstitution per manufacturer or clinician guidance. Standard storage window: 28d refrigerated.
Stack combinations
Commonly tracked alongside other recovery peptides in the same stack. Stack partners vary by protocol and clinician guidance.
Cycle length norms
Tracked users commonly run 28 on / 14 off. Cycle norms vary by individual and by clinician guidance. Pepture lets you configure any on/off window that matches your protocol.
Safety considerations
Every peptide carries context-specific risks. Work with a licensed clinician who knows your medical history before starting or adjusting a protocol. Stop and seek medical attention for severe injection site reactions, unexpected swelling, shortness of breath, persistent elevated heart rate, rash, or any reaction you did not anticipate. Pepture does not assess efficacy or safety for any individual.
