Our top pick is BPC-157, thanks to its uniquely broad research base spanning tendon, muscle, and gut repair alongside a favorable short-term tolerability profile in the available human data, while Collagen Peptides earns the budget and accessibility nod as the only non-injectable, over-the-counter option on this list, backed by randomized trials on skin hydration and joint comfort
If you use another B12 injection kit (hopefully not cyano B12), aim for at least 1 mg of B12 per shot, which is plenty
It has a longer half-life in the body, making it a favorable choice for some individuals

It has no therapeutic pharmacokinetic profile in this context because it is used only as a preservative/diluent at 0.9%
However, supplementing excessively high levels of B12 can have some adverse effects
