Well, its because blood loss is one of the primary causes of Iron deficiency

intensive protocols don't dramatically accelerate skin changes Longer cycles (6-8 weeks) may optimize collagen remodeling Some practitioners recommend concurrent topical GHK-Cu application for enhanced skin-specific effects Sun protection is essential during therapy to maximize benefits Consider complementing with vitamin C supplementation to support collagen synthesis Injury recovery focus For musculoskeletal injuries, tendon/ligament repair, or post-surgical healing: Consider starting with intensive protocol for 1-2 weeks before tapering to standard Injection site near (but not into) injury location may enhance local effects, though systemic administration is also effective Continue until recovery milestones achieved, extending beyond 4 weeks if necessary Combine with appropriate physical therapy and rehabilitation The wolverine stack (BPC-157 + TB-500 without GHK-Cu) may be preferred for pure injury focus Gut health focus For inflammatory gut conditions or gut healing: BPC-157 is the primary active component for gut effects Standard glow peptide protocol provides adequate BPC-157 dosing Some practitioners use standalone BPC-157 for pure gut focus Oral BPC-157 (stable variants) may provide enhanced gut-local effects Expect longer timelines for gut-related benefits

"BSH Cobalamin and Folate guidelines" published 2014 NICE published a new B12 deficiency guideline in 2024 I have some doubts about this guideline but I think it's worth reading
A part of the output was used to generate a broadband IR pulse in an OPA with an AgGaS 2 crystal (2.5-J pulse energy at the sample position, FWHM of ~350 cm 1 )
IV push, IV infusion over a set time, IM injection into a muscle, etc.)
