Gut & Recovery Support
BPC-157 and TB-500 — the guardrail stack. GI protection during GLP dose escalation and deep tissue recovery.
Mechanism of Action
Gastroprotection (BPC-157)
BPC-157 upregulates eNOS/NO system, increasing mucosal blood flow. Protects gastric epithelial barrier against GLP-induced gastroparesis and stress. Run from day 1 of any GLP protocol.
VEGFR2 Angiogenesis (BPC-157)
BPC-157 activates VEGFR2 → PI3K → Akt → eNOS cascade, driving new capillary formation at injury sites. Rate-limiting for tissue repair across multiple organ systems.
G-Actin Sequestration (TB-500)
Thymosin Beta-4 sequesters ~40-50% of cellular G-actin, regulating cell migration into wound zones. The mechanism behind TB-500's connective tissue and systemic repair effects.
Gut & Recovery: The Guardrail Layer
GLP-1 agonists at research-level doses produce significant GI side effects — nausea (43% incidence in Phase 2), diarrhea (34%), vomiting. The Clav stack addresses this directly.
BPC-157: GI Protection
BPC-157 (Body Protection Compound-157) is a 15-amino acid peptide derived from gastric juice. 36+ preclinical studies. No minimum toxic dose found in rodent models.
Primary mechanisms:
- NO system modulation → increased gastric mucosal blood flow
- Upregulates growth factors at injury sites
- Angiogenesis in healing tissue
- Direct gastroprotective effects
TB-500: Deep Connective Tissue
Thymosin Beta-4 sequesters G-actin, enabling controlled cell migration during tissue repair. Key for joint and connective tissue health during aggressive fat loss and body recomposition — when load-bearing tissues adapt to changing body mechanics.

Frequently Asked Questions
Why run BPC-157 with Retatrutide?
Retatrutide and all GLP peptides delay gastric emptying and alter gut motility — causing nausea and GI stress at higher doses. BPC-157 has documented gastroprotective effects via NO system modulation. It's the gut guardrail on an aggressive GLP protocol.
Can BPC-157 and TB-500 be combined?
Yes — they're commonly co-administered. BPC-157 covers gastric/mucosal protection; TB-500 addresses connective tissue and systemic tissue repair. Different mechanisms, fully complementary.
