Greska’s vs SES vs C60 Purple Power: The Real Cost Per Serving
Sticker prices don’t tell you what a C60 supplement actually costs you — what matters is the price of one daily serving. Compared that way, one brand is dramatically cheaper. Here are the numbers for all three, plus every Greska’s product price.
THE BOTTOM LINE
Greska’s Carbon-60 is the cheapest per serving — and it isn’t close. At about $1.69 a serving, it costs roughly 41% less than SES ($2.85) and 64% less than C60 Purple Power ($4.69) — because a Greska’s serving is a tiny ⅔-dropper, so each bottle stretches much further.
Cost per serving, side by side
Each figure uses that brand’s own recommended daily serving and its best-selling single bottle (Greska’s 45-day Sunflower Oil; SES Original 100 ml; C60 Purple Power 8 oz).

✓ lowest cost per serving. Monthly and yearly figures assume one serving per day, at each brand’s one-time bottle price. All three brands market their C60 as solvent-free; Greska’s makes its 100% solvent-free, no-solvents-ever process a central selling point.
Why Greska’s wins on cost per serving
It comes down to how much you take. SES and C60 Purple Power both recommend about a teaspoon (5 ml) a day. Greska’s recommends just two-thirds of a dropper — about 0.67 ml, roughly one-seventh of the volume. Greska’s C60 is 100% solvent-free — no solvents are ever used to make it, dissolve it, or preserve it — and ultra-fine (they claim particles “200,000× smaller” than typical C60 powder), so a much smaller amount is meant to do the job.
That tiny serving is why a small 30 ml Greska’s bottle delivers ~45 servings, while a larger 100 ml SES bottle gives ~20. Divide price by servings and Greska’s lands at $1.69, SES at $2.85, and C60 Purple Power at $4.69 per serving. Over a year of daily use that’s roughly $616 vs $1,039 vs $1,712 — Greska’s saves about $420 a year versus SES and $1,100 versus Purple Power.
Zero solvents, ever. Greska’s Carbon-60 is made with a 100% solvent-free process — no solvents are used at any stage, from producing the raw C60 to bottling the finished oil. For many buyers that’s the deciding factor, not just the price.
How we’re comparing, honestly: cost per serving uses each brand’s own recommended serving — Greska’s ⅔-dropper and the teaspoon that SES and Purple Power advise. Those serving volumes differ because each brand formulates and dilutes differently, and none of them publishes an exact C60-in-milligrams figure on these pages. So this compares the cost of following each label’s directions, which is what you’ll actually spend — not a lab-measured milligram-for-milligram dose.

These are three separate companies: Greska’s Carbon-60 (c60.com, by Robert “Bob” Greska), SES Research (sesres.com), and C60 Purple Power (shopc60.com, by C60 Shop, Inc.). They are often confused for one another but are not affiliated.
The takeaway
On the metric that reflects what you actually spend — cost per serving — Greska’s Carbon-60 is comfortably the cheapest of the three, at about $1.69 versus $2.85 for SES and $4.69 for C60 Purple Power. Its small ⅔-dropper serving means each bottle lasts far longer, so even though the sticker price sits between the others, the day-to-day and year-over-year cost is markedly lower. If lowest cost per serving is your priority, Greska’s is the clear pick.
