Patients should consult a qualified healthcare provider before beginning or changing any medical treatment. R2 Medical Clinic uses medications sourced from compounding pharmacies. Compounded medications are not approved by the U.S. Food and Drug Administration (FDA). Unlike FDA-approved medications, compounded drugs have not undergone FDA review for safety, effectiveness, or efficacy through the FDA drug approval process. While 503B outsourcing facilities are registered with and inspected by the FDA and must comply with Current Good Manufacturing Practice (CGMP) requirements, the compounded medications they produce are not individually approved by the FDA. Similarly, compounded medications prepared by 503A pharmacies are not FDA-approved and are primarily regulated by state boards of pharmacy, with FDA oversight under applicable federal law. # Thymosin Alpha-1 (Tα1)

Neovascularisation of the ischaemic border zone is critical for myocardial salvage and research applications. Tβ4 promotes cardiac angiogenesis through both direct endothelial cell effects (VEGFR2-PI3K-Akt-eNOS tube formation) and indirect cardiomyocyte paracrine effects (Tβ4-treated cardiomyocytes upregulate VEGF-A secretion). HUVEC tube formation assay (Matrigel GFR, 48-well format, IncuCyte quantification): Tβ4 (100 ng/mL-1 μg/mL) comparison to VEGF-A (50 ng/mL) positive control and SU5416 VEGFR2 inhibitor (1 μM) negative control. HUVEC migration (Boyden, VEGF-A 50 ng/mL lower chamber ± Tβ4 upper chamber: establishes whether Tβ4 is a direct motogen or requires VEGF-A). In vivo angiogenesis quantification: CD31 (PECAM-1) IHC (anti-CD31, BD Pharmingen 550274) in peri-infarct zone at 7d and 28d, image analysis (vessels/mm², vessel diameter distribution by image J, angiogenic index = vessel number × mean diameter²/field area). α-SMA+CD31 co-staining distinguishes mature arterioles (indicating functional neovascularisation supporting perfusion) from capillary sprouts (early angiogenesis). Laser Doppler perfusion imaging (LDPI, Moor Instruments LDI2) of post-infarct leg (hindlimb ischaemia model alternative) provides a non-invasive angiogenesis readout suitable for longitudinal tracking.
