Greska's C60 vs. The Competition
The cleanest C60 on the market — at the lowest cost per day. Here is the proof.
What You Actually Pay Every Day
These prices are pulled directly from each brand's website at their minimum recommended daily serving. The secret is serving size. Greska's nano-particle C60 requires only 0.67 mL per day. Every competitor requires 5 mL or more — that is 7.5 times more oil per dose, burning through their bottle far faster.

Every number pulled directly from each company's website. No estimates. No guessing.

📌 The reason Greska's costs less per day is not a smaller bottle — it is a smaller serving size. Nano-particle C60 is absorbed more efficiently by your body, so 0.67 mL delivers results that a full teaspoon of competitor oil cannot match.
What You Spend Over a Full Year
At each brand's minimum recommended daily dose, here is what your C60 costs over 365 days.
⚠️ ShopC60 recommends up to 3 teaspoons per day for many users. At that dose, the annual cost jumps well over $3,000 per year — compared to Greska's flat $617. That is a difference of over $2,400 every single year.
Every Advantage, Side by Side
Price per day is only one part of the story. Greska's leads on purity, manufacturing, particle size, and value across every category.

Greska's C60 vs. Others: The Size Difference
These microscope pictures show the size and shape difference between Greska's Carbon 60 powder and a popular competitor's powder.
Greska's Carbon 60 particles are more than 200,000 times smaller than all other as-produced Carbon 60 powders on the market.
Smaller particles absorb into your body far more efficiently. That is why you only need 0.67 mL per day instead of a full teaspoon — and why Greska's costs so much less daily.

💡 Smaller particles = better absorption = less oil needed = lower daily cost. This is the entire reason Greska's is $1.69/day while competitors charge $4–5+.

Uniform Shape. Consistent Size. Every Batch.
These Transmission Electron Microscope (TEM) images show Greska's Carbon 60 powder at extreme magnification — perfectly uniform 20-nanometer spheres, every single particle.
This consistency means every dose contains the exact same concentration of bioavailable C60. No variation. No settling. No guessing whether your bottle is as potent as the last one.

Zero Contaminants. Not One Atom.
High Angle Annular Dark Field Imaging (HAADF) shows exactly what elements are present in C60 powder from different manufacturers. The results are stark.
In Greska's C60 powder: zero contaminants detected. Not one atom of any foreign element.
In other popular brands: silicon, potassium, chlorine, sulfur, sodium, and magnesium were all found. These are the byproducts of solvent-based manufacturing that other companies use.

The Color Tells the Whole Story
If you have seen other C60 products with a deep purple or magenta color, that is not a sign of quality. It is the fingerprint of solvent-based processing. The standard industry method uses toluene — an aromatic solvent — to purify the C60 molecule. Even after removal steps, the purple color proves solvent chemistry was involved.
Greska's C60 is pure black. That is the natural color of clean, concentrated, solvent-free C60 suspended directly in organic oil. Nothing to hide. Nothing removed. Just pure C60 in clean oil.
Black = Solvent-Free
Greska's dark color proves C60 was never processed with toluene or solvents. What you see is exactly what it is — pure C60 in clean organic oil.
Purple = Solvent History
Purple C60 oil is the visual signature of toluene-based manufacturing. Even after "removal" steps, the color gives it away every time.
Made In-House, Start to Finish
Bob Greska makes the C60 himself. No outside powder supplier. No solvent at any stage. Complete control over purity from raw material to finished bottle.
No Middleman = Lower Cost
Because Greska's does not buy powder from an outside supplier, there is no markup chain. That savings goes directly to you — $1.69/day instead of $4–5+.
Before & After Greska's C60
The following images document observed changes from Greska's Carbon 60 — including blood cell behavior, skin response, and more.
What Exactly Is a Nanometer?
A nanometer equals 0.000001 millimeters — incredibly small. Watch this visualization to understand just how tiny Greska's C60 particles really are, and why that size makes such a difference for absorption.
