Signs of deficiency may include: Megaloblastic anemiaa condition of larger than normal red blood cells and a smaller than normal amount
It includes thiamine (Vitamin B1), which helps with energy and brain health, mainly for those with neurological issues
Facial flushing in the minutes after injection has also been reported, most likely reflecting an acute vasodilatory response to the peptide itself rather than the GH release
In research communities, these peptides are often discussed as complementary rather than directly competitive because: GHK-Cu is often chosen for collagen, skin, scar, and cosmetic tissue remodeling goals BPC-157 is often chosen for tendon, ligament, joint, muscle, and deeper recovery goals For that reason, many researchers discussing GHK-Cu vs BPC-157 eventually decide the better question is not which one is better, but which one better matches the tissue target?
