Can BPC-157 help you regain yourself
Larger vials (20mg+) make more sense once you have reached maintenance doses and confirmed retatrutide works well for your research goals
On the other hand, those with severe kidney problems taking high amounts of B12 may see a high level of toxicity since the excess vitamin B12 wont get eliminated from the body easily
First, a provider draws a small blood sample, much like a routine blood test
Getting B12 levels into normal range or overrange does not magically fix this damage overnight, it takes a lot of work - nerves regrow at 1mm a day for example, and often levels need to be maintained at very high ranges to alleviate symptoms
If your diet is solid, your gut works fine, and you have no symptoms, you're probably wasting your money
