This may be my take on things, but other brothers may say something else. The components BPC-167 and TB500 have been used by quite a few brothers in the past, which was BPC-150 and TB4. There were quite a bit of mixed results.
BUT, this is a warning for this specific product containing camphor and and menthol that penetrates the skin with the TB500 synthetic, it's meant to alleviate hard tissues from pains and aches, with a cellular restorative bioavailable loads. However, camphor and menthol tends to conflict the cellular regenerative processes during the ADP stages. TB500 also is known for higher concern for cancerous growth because it over triggers the ATP process, not allowing the cells to "rest". An abundant concentration will force the cells to grow abnormally. If you need more publications on this, let us know.
