How many units of GHK-Cu should I draw?

It depends on your vial size, BAC water, and dose. For a 5mg vial with 2mL BAC water, a beginner dose of 200mcg is typically 8 units on a U-100 syringe. Use the calculator above for your exact numbers.

How much BAC water should I add to GHK-Cu?

The standard amount is 2mL of bacteriostatic water for a 5mg vial. More water gives a more dilute solution — easier to measure small doses. Less water means fewer injections per vial. Adjust the BAC water slider in the calculator to see how it changes your syringe units.

How long does a GHK-Cu vial last?

At a beginner dose of 200mcg daily, a 5mg vial lasts about 25 doses. The calculator shows exact doses per vial for your selected tier.

What syringe should I use for GHK-Cu?

Most people use a U-100 insulin syringe (1mL / 100 units). For very small doses, a U-50 or U-30 syringe gives better precision. The calculator adjusts units automatically for whichever syringe you pick.

t½ = ~1 hour

After 1 half-life (1h): 50% remainsAfter 2 half-lives (2h): 25% remainsAfter 3 half-lives (3h): 12.5% remains

At a 500mcg dose: 50% = 250mcg remaining after 1h. Recommended frequency: Daily.

Disclaimer: This curve is a simplified first-order exponential decay model. Actual pharmacokinetics vary based on injection site, individual metabolism, body composition, and other factors. Half-life values are approximate and based on available preclinical and clinical literature. Many research peptides lack formal human pharmacokinetic studies.

About GHK-Cu

GHK-Cu is a naturally occurring copper-binding tripeptide that declines with age. It's one of the most studied anti-aging peptides, with research showing it stimulates collagen and elastin production, promotes wound healing, reduces fine lines and wrinkles, and even promotes hair regrowth. Available both as injectable and topical formulations, it works at the genetic level — activating over 4,000 genes involved in tissue repair and regeneration.
