Multi-Peptide + Copper Peptides 1% Serum
Reviewed by SerumTruth Editorial · Updated July 2026
The value benchmark of the category: multiple studied peptides at a disclosed copper level for roughly the price of a lunch. It is the obvious first serum to compare everything else against, even if you re-cap it fast.
- Evidence18 / 30
Strength of the research behind the key actives
- Copper Peptide (GHK-Cu): moderate evidence
- Matrixyl 3000: moderate evidence
- Argireline: limited evidence
- Score is the average of the key actives’ evidence grades.
- Potency20 / 25
Dosed at studied levels, not fairy-dusted
- Copper Peptide (GHK-Cu) (1%): dosed at a studied level
- Matrixyl 3000: dosed at a studied level
- Argireline: present, but below a studied dose
- Potency tracks how strongly the actives are dosed, led by the strongest, not how many there are.
- Delivery & stability6 / 20
Delivery tech + packaging that protects fragile actives
- Delivery: standard
- Packaging: clear dropper
- Air- or light-sensitive actives (Copper Peptide (GHK-Cu)), so packaging is scored.
- Formulation6 / 10
Disclosure, active breadth, and ingredient generation
- 1 of 3 actives disclose a concentration
- 3 key actives (breadth credit caps at 3)
- Current-generation or synergistic: Copper Peptide (GHK-Cu), Matrixyl 3000
- Value12 / 15
What a month of use costs vs. the category
- About $19 per month to use
- $32 for 30 ml, used about twice a day (about 0.3 ml each time), so a bottle lasts about 1.7 months
- Band: $6/month or less earns full marks, $60/month or more hits the floor.

What’s inside
| Active | Disclosed | Dose |
|---|---|---|
| Copper Peptide (GHK-Cu) | 1% | Studied |
| Matrixyl 3000 | n/a | Studied |
| Argireline | n/a | Light |
A genuine multi-peptide formula (copper peptides, Matrixyl 3000, Matrixyl Synthe’6, Argireline, SYN-AKE) that discloses its 1% copper level, which is unusual transparency at this price. It is lightweight and layers well. The frosted-glass dropper is the weak point for a copper peptide that oxidises.
How it’s delivered
Air- and light-sensitive actives (vitamin C, copper peptides) lose potency fast in the wrong packaging, so delivery and the bottle are scored, not just what’s on the label.
