I have some peptides (triz, bpc, tb-500). And have more peptides that I do bac water. I usually do 2ml for a 10mg amount of peptides. Any reason to avoid a higher concentration.
For instance I would be injecting 5 units of BPC, which I have tried to avoid using such a small amount of liquid being concerned about loss in the needle.
