He's translating both injected CHK-cu and orally ingested copper to milligrams of copper absorbed to make sure you are comparing apples to apples. If you inject 2 mg of GHK-cu, you absorb 0.31 mg of copper (16% of GHK-cu mass is copper X 100% bioavailability). If you eat the upper range of recommended dietary copper (2 mg) per day, you absorb ~0.6 mg (2 mg x estimated 40% bioavailability).
My takeaway is that unless your dietary intake of copper is unusually high, GHK-cu injections will not cause you to exceed the tolerable intake, and in many cases will not even cause you to exceed the recommended intake. Consequently, depending on your diet, there may be no reason to take breaks from GHK-cu treatment.
I have a question for you [USER=38526]@BadassBlues[/USER]: Are you administering the 2 mg per day as a single injection or morning and night 1 mg injections?
