There are reports of human injecting GHK-Cu bought from other companies. If someone does this watch the blood pressure which may decrease with a very high dose. I do not recommend injection but if you do this, the keep it to a total to 2 mgs to 20 mgs of GHK-Cu. A possible lethal dose, based on studies in mice, would be about 23,000 mgs injected IV at one time.
