Hes also pointed to gut applications, suggesting it can help with leaky gut and inflammatory bowel conditions

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

No serious adverse events have been systematically documented in human use to date, though the absence of systematic reporting infrastructure in the research peptide space means that adverse events are almost certainly underreported
While Vitamin B12 tablets are readily available, easy to use (you just pop it in your mouth!), and cheaper, the rate at which the vitamin absorbs in tablet form is relatively slow
