Likewise, BPC 157 ameliorates healing and recovers the impaired function of severely injured muscles that otherwise fail to spontaneously heal and plays a role after complete transection, crush, and denervation injuries [7780] and after succinylcholine intramuscular application, muscle lesion, neuromuscular junction failure, fasciculations, paralysis, and hyperalgesia [81]
The Mayo Clinic notes that even at therapeutic mega-doses, side effects are uncommon and mild: headache, nausea, diarrhea, fatigue, and a tingling sensation in extremities
However, studies suggest that supplementing with B12 does not reduce the risk of developing dementia or Alzheimers disease in older adults, or slow its progression
Vitamin B12 injections allow for quicker absorption into the body and you feel the effects (increased energy, focus, improved sleep) within 48 - 72 hours and the effects last for about 1 week.
