| Attribute | Thymosin Alpha-1 (TA1) | BPC-157 |
|---|---|---|
| Category | Immune & Inflammation | Injury, Repair & Recovery |
| Research Stage | Approved (International) | Preclinical |
| Mechanism of Action | Thymosin alpha-1 does not act through a single canonical receptor in the way many peptides do. Its mechanism is pleiotropic, involving pattern-recognition receptors, modulation of immune cell maturation and function, and shifts in cytokine signaling patterns.… | Nitric Oxide (NO) System Modulation BPC-157 exerts a central integrative effect through modulation of the nitric oxide system. Studies by Seiwerth et al. (2022) demonstrated that BPC-157 counteracts both NO-excess and NO-deficiency states, functioning as a… |
| Half-Life | ~2 hours | ~4 hours (estimated from animal pharmacokinetic data) |
| Typical Dose Range | 1,600 mcg (1.6 mg) per injection (standard clinical dose) | 200-500 mcg subcutaneous 1-2x daily (community protocols); 1-10 mcg/kg in animal studies |
| Dosing Frequency | 2–3 times per week subcutaneous | Twice daily (AM and PM) for optimal serum levels; once daily acceptable |
| Administration | Subcutaneous | Subcutaneous, Oral, Intraperitoneal, Intravenous |
| Side Effects | Tα1 has one of the most benign side-effect profiles in the peptide space, supported by 45+ years of clinical experience in approved indications. Most users experience no acute side effects beyond mild injection site discomfort. Common (5-15% of users): -… | Generally well-tolerated. Mild nausea or GI discomfort during initial use. Temporary increase in pain/inflammation at injury site (healing response). Rare: drowsiness, dizziness, mild headache. Very rare: transient changes in blood pressure. |
