We typically recommend: Weekly or bi-weekly if youre addressing a deficiency or need support during weight loss Monthly for maintenance and overall wellness Well help you figure out the right schedule based on your symptoms, lifestyle, and goals
The absence of large-scale human trials makes the true frequency of allergic responses across broader populations unknown
Standard ratios: 2mg peptide + 2ml water = 1mg/ml (1000mcg/ml) 5mg peptide + 2ml water = 2.5mg/ml (2500mcg/ml) 5mg peptide + 1ml water = 5mg/ml (5000mcg/ml) 10mg peptide + 2ml water = 5mg/ml (5000mcg/ml) How to choose: More water (2-3ml per vial): Easier to measure small doses accurately Larger injection volumes (0.2-0.3ml) Lasts longer (more injections per vial) Less water (1ml per vial): Higher concentration Smaller injection volumes (0.05-0.1ml) Fewer injections per vial Most people use 2ml of water for 5mg vials
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?
