GHK-Cu in the Philippines

GHK is a tripeptide with the sequence glycyl-L-histidyl-L-lysine, found naturally in human plasma. It binds copper(II) with high affinity, and the resulting complex — GHK-Cu — is what research works with. The copper is not an additive: it is part of the molecule, which is why the reconstituted solution has a distinct blue colour.

A 50mg vial is a larger cake than most research peptides, so it takes more water and dissolves a little more slowly. Give it a few minutes at room temperature rather than agitating it.

Concentration is simply vial milligrams divided by water volume. With a 50mg vial, the common working choices are:

1. 1Wipe both stoppers with an alcohol pad and let them dry.
2. 2Draw the chosen volume of bacteriostatic water.
3. 3Angle the needle so the water runs down the inner glass wall, not onto the cake.
4. 4Let the vial sit; swirl gently if needed. Never shake.
5. 5Once fully clear-blue, label the vial with the concentration and the date.

• Unopened lyophilized vial: stable at room temperature in transit; refrigerate at 2–8°C for long-term holding, protected from light.
• Reconstituted: refrigerate at 2–8°C and use within roughly 21–28 days.
• Do not freeze reconstituted solution.
• Keep away from strong reducing agents and prolonged direct light — copper complexes are light sensitive.
• Discard on cloudiness, particulates, or loss of the characteristic blue colour.

GHK-Cu appears in published work on extracellular matrix remodelling, collagen and glycosaminoglycan synthesis, antioxidant and anti-inflammatory signalling, and gene expression profiling. Its plasma concentration in humans is documented to decline with age, which is why it recurs in ageing and repair research models.

Bacteriostatic water is sold separately and is required to reconstitute the vial — it can be added on the product page in one click.

1. 1Confirm the stated milligrams per vial — 50mg vials and 100mg vials are priced very differently per milligram.
2. 2Ask which laboratory issued the analysis and whether the report can be verified independently.
3. 3Check the report covers purity, quantity, and endotoxin, not purity alone.
4. 4Confirm the powder is described as blue lyophilized GHK-Cu, not plain GHK without copper.
5. 5Confirm the seller ships with tracking and states research use only.
