Thymosin Beta 4 (TB500) 2mg is a synthetic 43-amino acid peptide engineered to replicate the functional active sequence of naturally occurring Thymosin Beta-4 (Tβ4). Renowned in regenerative biochemistry for its low molecular weight and high systemic mobility, TB500 plays a crucial role in actin sequestration, cellular migration, micro-vascular angiogenesis, and collagen remodeling. By accelerating soft tissue repair across tendons, ligaments, and muscle fibers while lowering chronic inflammatory signaling, this lyophilized 2mg vial provides an ideal entry point for targeted recovery cycles. Third-party HPLC lab-tested to guarantee active compound purity exceeding 98%.
YK-11 5mg (methyl (2E)-2-[(3r,5aS,6R,8aS,9R,10A-S,11S,12aS)-6-fluoro-11-hydroxy-10a,12a-dimethyl-1,3,4,5,5a,6,7,8,8a,9,10,11,12,12a-dodecahydrospiro[cyclopenta[a]phenanthrene-2,2'-[1,3]dioxolane]-3-yl]acetate) is a unique steroidal selective androgen receptor modulator (SARM) and gene-modulating myostatin inhibitor. Engineered to bypass natural genetic limits on muscle growth, YK-11 binds to androgen receptors to induce significant expression of follistatin—a naturally occurring glycoprotein that directly neutralizes myostatin. By deactivating the body's natural limits on muscle expansion, YK-11 5mg promotes dense muscle fiber hypertrophy, skeletal strength, and cellular recovery without converting into estrogen.
