| Standard Dose | Research indicates 250-500 mcg twice daily via oral capsule on empty stomach. | Research indicates dosing remains experimental. Mouse studies used 5 mg/kg IV, three times weekly. |
| Timing | On empty stomach, 30 minutes before meals. Twice daily dosing (morning and evening) provides consistent levels. | No established timing protocol. |
| Cycle Duration | 4-12 weeks. Oral form enables easier long-term use compared to injectable. | Mouse studies used intermittent dosing (3x/week for several weeks). Human protocols not established. |

Oral-stable BPC-157, typically formulated as the arginate salt, retains the same mechanism as standard BPC-157 — promoting angiogenesis via VEGFR2/PI3K/Akt/eNOS and Src-Caveolin-1-eNOS pathways, enhancing nitric oxide production, and stimulating tendon fibroblast growth and collagen formation. The arginate salt provides a protective buffer against gastric acid degradation, maintaining peptide integrity across a wider pH range. BPC-157 demonstrates remarkable native stability in human gastric juice (24+ hours), and the arginate form reportedly achieves 7-fold greater oral bioavailability compared to the acetate salt in preclinical studies.

FOXO4-DRI is a D-retro-inverso peptide that selectively targets the FOXO4-p53 protein-protein interaction in senescent cells. In senescence, FOXO4 binds p53's disordered transactivation domain (TAD2) in the nucleus, preventing p53 from translocating to mitochondria where it would trigger apoptosis. FOXO4-DRI competitively disrupts this interaction, causing nuclear exclusion of p53 and its redirection to mitochondria, selectively inducing apoptosis in senescent cells while sparing healthy cells. The D-retro-inverso configuration provides protease resistance.
