Short answer
Skin and pigment research peptides are compounds studied in skin, collagen and melanocortin research. The group covers GHK-Cu, a copper-binding tripeptide, and melanotan 2, a melanocortin receptor agonist.
What are skin and pigment research peptides?
Skin and pigment research peptides are compounds studied in skin, collagen and melanocortin research. The group covers GHK-Cu, a copper-binding tripeptide, and melanotan 2, a melanocortin receptor agonist.
GHK-Cu is a copper-binding tripeptide first identified in human plasma. Melanotan 2 is a synthetic melanocortin receptor agonist and is Schedule 4 in Australia.
Which compounds are in this group?
| PRODUCT | WHAT IT IS | STRENGTHS | FROM |
|---|---|---|---|
| GHK-Cu | Copper(II) complex of the endogenous tripeptide glycyl-L-histidyl-L-lysine (GHK) | 50mg | A$58 |
| Melanotan 2 | Synthetic cyclic heptapeptide analogue of alpha-melanocyte-stimulating hormone (melanocortin receptor agonist) | 10mg | A$68 |
How do these compounds differ?
GHK-Cu is a copper complex of a plasma tripeptide; melanotan 2 is a cyclic analogue of alpha-MSH.

How is each batch tested?
Every batch is tested by an independent lab, [lab], before it goes on sale: purity by HPLC and identity by mass spectrometry. The certificate is published under the batch number printed on the vial.
Search any batch number in the certificate library. The testing page explains each method and its limits.
Are these peptides legal in Australia?
Legal status depends on the compound. 13 of the 28 research compounds in this range are listed in Schedule 4 of the Poisons Standard (prescription only), counting tesamorelin under the group entry for growth hormone-releasing hormones. 7 are also listed in Appendix D clause 5, which makes possession without authority an offence. The rest are not named in the Poisons Standard. Each product page states its compound's status, and Peptides Collective sells every product for laboratory research use only.
The legal guide explains each schedule, Appendix D and the WADA list.
How should they be stored?
Store sealed lyophilised vials frozen (about -20 degrees Celsius), dry and dark. Keep reconstituted solutions at 2 to 8 degrees Celsius and avoid repeated freezing and thawing.
BAC Water (sterile water with 0.9% benzyl alcohol) is the usual laboratory solvent. Dilute acetic acid is the alternative for peptides that dissolve poorly in water. Each product page names the solvent for its compound.
The storage guide and reconstitution guide cover laboratory handling.
Skin questions
What are peptides for the skin?
Peptides studied in skin research include GHK-Cu, a copper-binding tripeptide, and melanotan 2, a melanocortin receptor agonist. Both are sold here for laboratory research only.
What does a copper peptide do?
GHK-Cu, the best-known copper peptide, binds copper(II) ions. Cell and animal studies examine its role in wound and collagen biology.
Are these compounds legal to buy in Australia?
Legal status depends on the compound. 13 of the 28 research compounds in this range are listed in Schedule 4 of the Poisons Standard (prescription only), counting tesamorelin under the group entry for growth hormone-releasing hormones. 7 are also listed in Appendix D clause 5, which makes possession without authority an offence. The rest are not named in the Poisons Standard. Each product page states its compound's status, and Peptides Collective sells every product for laboratory research use only.
Which compounds here are Schedule 4?
Melanotan 2 is listed in Schedule 4 of the Poisons Standard. GHK-Cu is not named.
Is every compound in stock?
Every product is in stock at the time of this update. Stock shows on each product page and in the cart.
Where do orders ship from?
Orders ship tracked from Western Australia. Orders placed before [cut-off] leave the same business day. Delivery estimates for each state are on the shipping page.
What do these compounds have in common?
Both are studied in skin research, through different mechanisms: copper binding (GHK-Cu) and melanocortin receptors (melanotan 2).
