related full-length recombinant thymosin beta-4 (a different formulation than the marketed TB-500 fragment) has also been examined in small human studies for cardiac and dermatologic indications Examined in preclinical models, including diabetic rat Achilles tendon and rat ligament-injury studies, for actin-binding, cell-migration, and angiogenic activity that researchers have proposed as a mechanism for tendon and ligament repair, though this literature remains comparatively sparse for musculoskeletal applications specifically Known risks and side effects: Because TB-500 is manufactured and sold without FDA oversight as a "research chemical," independent testing and industry reporting describe wide variability in purity (with some products measured well below labeled potency) and contamination with heavy metals or bacterial byproducts, unlike pharmaceutical-grade recombinant thymosin beta-4 used in registered clinical trials Thymosin beta-4's core mechanisms, angiogenesis and cell migration, are also pathways exploited by tumors

However, the peptide's ability to promote tissue repair and create an environment conducive to overall health might indirectly influence GH function
Additionally, while the most common side effect was mild to moderate gastrointestinal upset, there were fewer events per 100 patients across all of the cagrilintide treatment groups in comparison to the subjects receiving 3.0 mg of liraglutide [1]
