Protocol notes
This is a research-only stack. The 'athletic' framing reflects the multi-tissue injury profile typical of sports-medicine research, not an endorsement for human use in athletic populations. BPC-157 and TB-500 are listed under WADA S0; LL-37 and GHK-Cu are not currently listed but researchers should confirm against the current annual WADA Prohibited List before any in-vivo work that involves athletic subjects. The mixed-tissue model requires multiple injury types in the same animal (e.g. tendon transection + skin excisional wound) and careful per-tissue endpoint design.
Mechanistic rationale
Athletic injury research models often combine multiple tissue types — tendon, ligament, muscle, dermal abrasion, and (in contact-sport models) contaminated wound. This stack addresses that heterogeneity. BPC-157 brings tendon and gut-axis activity with strong angiogenic effect, TB-500 brings actin-sequestration-driven cell migration into hypoxic injury sites, GHK-Cu drives dermal collagen synthesis and antioxidant defence at skin abrasion sites, and LL-37 provides direct antimicrobial activity that limits infection-driven wound conversion in contact-sport contamination models. The combination is wider than any single-tissue stack but mechanistically defensible across the injury domains a sports-medicine model is designed to capture.
Endpoint suggestions
Per-tissue endpoints: tendon — biomechanical load-to-failure and collagen fibril alignment; skeletal muscle — central nucleation density, fibre cross-sectional area recovery, and grip strength; skin — wound-closure rate and re-epithelialisation grade; infected-wound — bacterial colony counts and infection-conversion rate. Systemic endpoints: serum creatine kinase as a global muscle-damage marker, and CRP or IL-6 as inflammatory composite readouts. Time-course design (days 3, 7, 14, 28) captures the sequence of inflammatory, proliferative, and remodelling phases.
Confounders
Sample size scales steeply with the number of tissue endpoints — power calculations should reflect the per-tissue effect-size rather than a global composite. Exercise rehabilitation arms (treadmill running, loading protocols) are themselves potent healing modulators and should be either standardised across arms or factorial in design. Combining LL-37 with whole blood or serum-rich vehicles requires low-binding labware due to its plastic-adsorption behaviour, and the GHK-Cu copper complex must be kept away from reducing agents in the formulation.
