Ergo Synthol Site Enhancement Oil  Product Description

Synthol is a non-anabolic drug used to locally increase muscle volume and give it perfect shape. The drug was developed by German chemist Chris Clark in the 1990s.  Especially common in professional sports before competitions. The name “synthol” occurs by analogy with the nuclear fusion reaction, however, this name was already patented, so later the synthol began to be sold under the brand Pamp-and-Pose (Pump-N-Pose – “download and pose”). However, original synthol is officially positioned as a pose oil with the wording “site enhancement oil” for unobstructed distribution.

Romario Dos Santos Alves, a 25-year-old amateur bodybuilder from Brazil, used synthol to increase muscle volume

The composition of synthol:

  • 85% of the oil is medium chain triglycerides (Medium Chain Triglycerides), for example, caprylic acid in the Syntherol brand. Often used purified sesame and coconut oil.
  • 7.5% lidocaine as a local anesthetic
  • 7.5% benzyl alcohol as a preservative


Synthol, like formolbolone, contributes to a local increase in muscle volume at the injection site.

The manufacturers keep the composition of the original preparation in secret, however some information about it nevertheless leaks out and often serves as a support for the manufacturers of the counterfeit preparation. For example, Dan Ducain argued that in the analysis he found only fatty acids with 8-12 carbon atoms in the molecule, lidocaine and benzyl alcohol.

A possible mechanism of action includes an increase in the volume of fibers due to the absorption of oil into them or else the “flow” of fibers into the oil base, as well as local inflammation, which is accompanied by muscle swelling.


Synthol, administered in 4–8 weekly courses: first, 1 ml in the muscle with an interval of 3-5 days, then 2 ml, and so on, until the muscle continues to increase in volume.

According to the literature, synthol allows you to increase the girth of small muscles by 3-8 cm. It absorbs relatively slowly. However, some say that the main part of the drug is eliminated within a few months.


The use of synthol is accompanied by a number of serious side effects:

  • Fatty embolism of the lungs and brain, which can lead to pulmonary infarction and ischemic stroke
  • Nerve damage
  • Infectious complications
  • Sclerosing lipogranulomatosis of muscles, the formation of cysts and ulcers
  • Allergic reactions (vasculitis)
  • Aesthetic problems (muscle sagging)


Also, responses of athletes in the press also make it clear that the use of synthol makes training very difficult due to excessive swelling of the muscles. Because naturally, this leads to a reduction in the duration and intensity of classes. Also, unlikely a person whose hands pumped with something like silicone worked intensively.

Another aspect of the use of synthol is moral and ethical. While, the opinion of the repeated “Mr. Olympia” by Dorian Yates: “My attitude to synthol is the same as all implants. This is an attempt to improve the physique with cosmetic methods, avoiding the hard work that makes bodybuilding a real sport. As far as I understand, synthol does not improve the results but it only inflates and distorts the muscles. The strange, unnatural shape of the delta and the hilly triceps, now too often encountered in competitions. While manipulations with synthol and other implants not prohibited, bodybuilding risks losing that athletically appeal, which we all appreciate. ”
