ghk cu and bpc 157 together BPC-157 + TB-500 + GHK-Cu GLOW Blend BPC-157 vs GHK-Cu vs TB-500:
Description
B12 injections are administered like any other injection, typically in the thickest part of the upper arm muscles
Using your insulin syringes you should draw as follows according to your dose

Published evidence indicates that B12 deficiency can make HbA1c unreliable, but the direction of the distortion whether the result is spuriously high or spuriously low is variable and may depend on the degree of anaemia, the specific HbA1c assay used, and other concurrent conditions

The 1:1 represents a balanced approach to covering both mechanisms
