This distinction is worth stating clearly because much of the online discussion about BPC-157 conflates the regulatory position (relevant to competitive athletes) with the research and safety discussion (relevant to everyone)
The effect of injected synthetic thymic peptides on T helper cell activity increased with an increase in the injected dose, but the efficiencies of THF-y2 and thymopentin were 400-fold and 8fold greater than that of thymosin aI, respectively." More recently, we investigated the production of cytokines, namely, interleukin2 (IL-2) and IL-4, by mitogen-stimulated spleen cells from aging mice when cultured with THF-y2 or a recombinant murine cytokine (IL-lp, IL-2, IL-3, IL-4, or IFN-y)
Rather than chasing perfection, focus on creating an environment conducive to your goals
The outcome suggested that a transient and limited increase in gut permeability compared with the unregulated breach of the gut barrier function due to the TJ deregulation and epithelial cell apoptosis can rather lead to a dominant regulatory immune response to gut microbiota antigens and to a net anti-inflammatory effect
