Combine the two. Get them in separate vials so the amounts can be adjusted more accurately.
Considering beginning BPC-157 to address pain in my knee and lower back. Is it better to try BPC-157 on its own first, or combine it right away with TB-500? I'd like to know others' results with this. Also, TB-500 rarely gets used alone and is usually combined with BPC. Why is that the case, or has it just become common practice?
