Stearic Acid VS. Cholesterol – Which one should you look for in your pellet?

Hormone pellets are made of various strengths, sizes and combinations. One of the main differences in pellets we want to look at is the use of stearic acid versus cholesterol in the pellets.

First, what exactly is stearic acid and what is cholesterol?

ste·ar·ic ac·id


a solid saturated fatty acid obtained from animal or vegetable fats.



a compound of the sterol type found in most body tissues. Cholesterol and its derivatives are important constituents of cell membranes and precursors of other steroid compounds, but a high proportion in the blood of low-density lipoprotein (which transports cholesterol to the tissues) is associated with an increased risk of coronary heart disease.

How is stearic acid used in pellets?

At Qualgen, we use stearic acid as a lubricant for our one-of-a-kind patented pellet machine presses, whereas, other pellet manufacturers use off the shelf tablet presses to mold their pellets, normally requiring a binder to get the same pressure as Qualgen gets from its patented machines. This is a major difference between Qualgen and other pellet manufacturers.

Qualgen only uses 0.5% stearic acid. In other words, less than 1% of the pellet has anything other than the natural hormone. Under FDA standards, anything less than 1% is considered non formulary, therefore the pellets at Qualgen are considered 100% pure hormone. Most pellet manufacturers use between 4-6% of other fillers in their pellets, meaning the pellet you are getting from other manufacturers is between 94-96% hormone. This is a major difference between Qualgen pellets and any other pellet made in the world.

We know it's important to compare your options!

Is stearic acid safe?

Stearic acid has been verified to be of low concern based on experimental and modeled data and is considered nontoxic and biocompatible with the human body. Stearic acid is a naturally occurring fatty acid found in animal and plant fats.

Qualgen’s pellets are cholesterol free – stearic acid is the industry standard for a reason.

Why don’t we use cholesterol in our pellets?

Testosterone is derived from cholesterol, so we can see how this seems like a great option! However, we at Qualgen, did early testing using dextrose and cholesterol and found that stearic acid is actually better than using dextrose or cholesterol, because cholesterol does not dissolve as effectively as stearic acid. Both stearic acid and cholesterol can cause no harm to your body nor the pellet implantation. As discussed earlier, most pellet manufacturers use 6% fillers, if that is the case you would be adding an average of (average male 10 testosterone 200mg pellets) 80mg of cholesterol to the body. This is not needed or necessarily a good thing to add to the body.

Unlike the other long-chain saturated fatty acids, stearic acid has no effect on lipoprotein cholesterol concentrations in men or women(1). Results from the study by Kelly et al. (2001) indicate that stearic acid (19 g/day) in the diet has favorable effects on thrombogenic and atherogenic risk factors in males; the authors recommend that the food industry consider enriching foods with stearic acid instead of palmitic acid and trans fatty acids. Thus, stearic acid is nontoxic and biocompatible with the human body.

Stearic acid is the second most common saturated fat in the American diet. Compared with carbs or other saturated fats, stearic acid lowers the "bad" LDL cholesterol slightly or has neutral effects. This suggests it may be healthier than many other saturated fats (2, 3, 4). Research shows that stearic acid is partly converted to oleic acid, a healthy unsaturated fat, within the body. Stearic acid is considered a healthy saturated fat.

These are positive effects on the body, hence the reason we use stearic acid.

Ultimately, Qualgen pellets are the PUREST pellets made in the world.
