|---|---|---|
| Category | Peptides | Peptides |
| Standard Dose | Research indicates 250-500 mcg twice daily via oral capsule on empty stomach. | Research indicates 100-300 mcg administered before bedtime via subcutaneous injection or intranasal. |
| Timing | On empty stomach, 30 minutes before meals. Twice daily dosing (morning and evening) provides consistent levels. | 30-60 minutes before desired sleep onset. Evening only. |
| Cycle Duration | 4-12 weeks. Oral form enables easier long-term use compared to injectable. | 2-4 week cycles with equal rest periods to prevent tolerance. |

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.

DSIP is a naturally occurring nonapeptide (Trp-Ala-Gly-Gly-Asp-Ala-Ser-Gly-Glu) originally isolated from rabbit brain hypothalamus in 1977. It modulates GABAergic neurotransmission by potentiating GABA-activated currents in hippocampal and cerebellar neurons while blocking NMDA-activated potentiation in cortical neurons. It also interacts with opioid-associated receptors, modulates serotonin and dopamine systems (increasing serotonin levels), and promotes delta wave (slow-wave) sleep through mechanisms that remain incompletely characterized.
