You'll learn about their potential benefits, considerations before use, and where to find them

What type of B12 injection is commonly used in the UK

Safety, Sourcing, and Why Medical Oversight Is Non-Negotiable BPC-157 has a strong safety record in animal studies notably, the lethal dose (LD1) has not been achieved across decades of preclinical research, and it has been used in human ulcerative colitis and multiple sclerosis trials without reported toxicity.6 But the absence of adverse events in animals does not translate directly to human safety, particularly at unregulated doses from unverified sources

Its also possible that a crash follows the initial boost of energy as the body adjusts to the sudden influx of B12

Further, NICE and the BNF says that if there are neurological symptoms present, then every other day injections are the recommended treatment, so all the points you make about B12 being stored and sufficient are not really relevant
