AHK-CU Strength Comparator

The AHK-Cu Research Pair contains two vials of AHK-Cu, also designated Copper Tripeptide-3, at 50 mg and 100 mg — 150 mg in total. Both vials hold the same compound to the same specification, differing only in fill mass. Two masses allow a target concentration to be prepared at two different volumes without serial dilution.

Key Takeaways

• This pair contains one 50 mg vial and one 100 mg vial of AHK-Cu, supplied lyophilized, 150 mg in total.
• Both vials contain the same compound produced to the same specification; fill mass is the only difference between them.
• Two fill masses allow a given target concentration to be reached at two different prepared volumes.
• AHK-Cu is designated Copper Tripeptide-3 and is a synthetic analog of GHK-Cu, which carries a substantially larger published literature.
• Both vials are supplied strictly for laboratory research and are not intended for human consumption, therapeutic use, veterinary use, or diagnostic applications.

What’s Included in This Research Pair

Both vials are supplied as pale blue lyophilized powder with batch documentation.

Both Vials Contain the Same Compound

The 50 mg and 100 mg vials contain identical material. Same compound, same specification, same production process — only the quantity of powder in the vial differs.

This is worth stating explicitly because vial size is sometimes assumed to indicate grade or preparation differences. It does not. A 100 mg vial of AHK-Cu is not a different product from a 50 mg vial, and neither is formulated for a different research area.

Fill mass is a practical variable. It determines the concentration range a single vial can reach and how much solution one reconstitution produces. It does not affect what the compound is.

Choosing Between the Two Fill Masses

Neither fill mass is preferable in general. The choice depends on the work:

• The 50 mg vial suits smaller preparations and higher concentrations at low volumes.
• The 100 mg vial suits larger prepared volumes at the same concentration, or higher concentrations where volume is constrained.
• Holding both suits work spanning a concentration range, or where the second vial is retained lyophilized as reserve material while the first is in use.

Lyophilized material is more stable than material in solution, so retaining the unused vial in its lyophilized state until required is generally preferable to reconstituting more than an experiment needs.
