GHK-Cu + SNAP-8 Peptide Renewal Serum vs Copper Peptide Renewal Serum
Amplified Glow sells two copper peptide facial serums with similar names, similar positioning and different specifications. This page compares every attribute the brand publishes for both, in the same order, using only first-party information.
Both columns here are Amplified Glow products, and every value comes from the brand’s own product pages — so it’s a like-for-like comparison you can check for yourself.

Choose GHK-Cu + SNAP-8 Peptide Renewal Serum when
- The disclosed copper peptide percentage is what you are shopping on — 0.15% is the highest in the Amplified Glow skincare range.
- You want to spend less up front, at $21.00 rather than $30.00.
- You want more than two named peptides in one bottle.
- You are trying a peptide serum for the first time and would rather not commit to a large bottle.
Consider Copper Peptide Renewal Serum when
- Cost per millilitre is your priority — $50.00 per 100 mL against $70.00.
- You already know a copper peptide serum suits your routine and will finish a 60 mL bottle.
- You prefer both named peptides to map cleanly onto INCI names, which is true here and not for SNAP-8.
The concentration difference is real but narrow
0.15% against 0.1% is a 50% relative difference in disclosed copper peptide concentration. That sounds substantial stated as a ratio and is a small absolute difference stated as a percentage of the formula.
What it does not establish is that one serum outperforms the other. The formulas differ in more than one variable at once — different second peptides, different hydration systems, different volumes, and an undisclosed remainder in both cases. Amplified Glow publishes no comparative testing, so a concentration difference is a specification difference and nothing more.
The price gap runs opposite to the concentration gap
The serum with the higher disclosed concentration is the more expensive one per millilitre, and the cheaper one per millilitre is the more expensive one in total. That is the actual trade-off, and it does not resolve to a single right answer.
If you have not used a copper peptide serum before, the smaller bottle limits what you spend to find out whether the format suits you. If you already know it does, the larger bottle costs 29% less per millilitre. Our 30 mL versus 60 mL comparison covers the part that gets skipped: whether you will actually finish the larger bottle.
What neither product tells you
Neither product page publishes a full ingredient list as text. Neither publishes a concentration for its second peptide. Neither describes the packaging. If you need to screen for a specific ingredient before applying a leave-on product to your face, neither serum can be screened from the website alone.
That is a shared limitation rather than a point of difference, which is exactly why it belongs in a comparison — the row that reads the same in both columns is often the most useful one on the page.

Frequently asked questions
Which serum has more copper peptide?
The GHK-Cu + SNAP-8 Peptide Renewal Serum discloses 0.15%; the Copper Peptide Renewal Serum discloses 0.1%. Note that the 60 mL bottle contains more total product, so at those concentrations it contains more copper peptide overall despite the lower percentage.
Which is better value?
Per millilitre, the 60 mL Copper Peptide Renewal Serum, at $50.00 per 100 mL against $70.00. In total outlay, the 30 mL serum at $21.00. Neither is better value in the abstract — it depends on which you are optimising.
Are both fragrance free?
Yes. Amplified Glow states fragrance-free status explicitly for both, which it does not do for most of its other skincare products.
Can I use both together?
Amplified Glow doesn’t publish guidance on using two of its serums together, so there’s no reliable answer to give. If you’d like to try it, the brand’s customer service is the best place to ask.

GHK-Cu
GHK-Cu is a small peptide complexed with copper. In cosmetics it appears under the INCI name Copper Tripeptide-1 and is used as a conditioning ingredient. It is the ingredient every Amplified Glow copper peptide product is built around, and the only one for which the brand publishes concentrations — between 0.1% and 0.15% depending on the product.

SNAP-8 is a trade name suppliers use, not the standardised (INCI) name that appears on an ingredient list. Amplified Glow names it for three products but doesn’t publish the ingredient list, so the exact ingredient behind "SNAP-8" on these labels can’t be confirmed — and a trade name and an ingredient-list name aren’t interchangeable.
Read the ingredient page →Polysaccharide salt; humectantSodium hyaluronate
Sodium hyaluronate is the sodium salt of hyaluronic acid, used in cosmetics as a humectant — an ingredient that attracts and holds water. It is the most widely used ingredient in the Amplified Glow range, disclosed in eleven of the fifteen products.

How to compare peptide serums
Compare the attributes that are actually published and actually comparable: disclosed concentration, net contents, price per millilitre, fragrance status and whether a full ingredient list exists. Do not compare on peptide count, marketing language, or research about isolated ingredients — none of those distinguishes one finished product from another.
Read the guide →GuideHow to interpret price per ounce
Price per unit is a fair comparison between products of the same format with the same job. It breaks down across formats, across formulas with different disclosed actives, and whenever you do not finish the container. The assumption underneath every per-unit calculation is that you use all of it — and for products people try and abandon, that assumption often fails.
