Our group, working with partially deficient IGF-1 mice, has demonstrated that the liver is capable of expressing IGF-1R (which under physiological conditions it does not [99]) as a defence mechanism (peer review)
Peptide blends Pre-formulated peptide blends like the wolverine stack (BPC-157 + TB-500) or glow peptide blends (TB-500 + BPC-157 + GHK-Cu) come with multiple peptides in a single vial
A nasal spray is also available but is not considered the best treatment for severe deficiency because B12 is not absorbed as well as it is via injection
This includes: Pernicious anemia Crohns disease or celiac disease Gastric surgery or gastrointestinal disorders For mild deficiency, starting with 1,000 mcg of Vitamin B12 weekly is common
Site rotation: If using injection routes, rotate sites to avoid localized tissue effects
The pain is typically caused by inflammation at the injection site as your immune system responds to the vaccine
