Frequently Asked
What BAC water volume gives the cleanest microdose precision for GHK-Cu?
A 10 mL reconstitution of a 50 mg GHK-Cu vial yields 5000 mcg/mL, which works out to 50 mcg per insulin unit on a 100-unit U-100 syringe. This makes targets like 100 and 250 mcg land on round unit marks instead of fractional half-units, which is the main precision constraint for microgram-scale research dosing.
How many micrograms is one insulin unit of GHK-Cu at this dilution?
At 50 mg per 10 mL of BAC water, each unit on a 100-unit insulin syringe (1 unit = 0.01 mL) delivers 50 mcg of GHK-Cu. The full draw chart for 100, 250, 500 mcg targets is calculated on this page.
Can I use a different BAC water volume?
Yes. Larger BAC water volumes produce lower mcg/mL concentrations, which improves precision for very small doses but increases the injection volume. The alternative-volume table on this page shows what happens at 5 mL and 8 mL so the precision tradeoff is explicit. Always verify with the main GHK-Cu calculator before drawing.
Why does sub-100 mcg precision actually matter?
At the microgram scale, the difference between adjacent insulin unit marks can represent a 50-100% dose change. A single unit error on a target near 100 mcg can double or zero the intended dose. Topical and subq research use cases routinely target sub-milligram per-event doses for follicular and cosmetic protocols.
Does the ASCEND main GHK-Cu calculator handle these doses too?
The main /calc/ghk-cu/ page handles the full dose range for GHK-Cu including the milligram presets. This microdose page is a focused entry point for sub-milligram research targets and links into the main calculator with the dilution pre-filled.
