Synthol is a site enhancement oil, made up of 85% oil, 7.5% lidocaine, and 7.5% alcohol. It is injected directly into muscles to make them appear bigger. Synthol is not a steroid, and it does not increase muscle strength. It is purely cosmetic. The use of synthol can lead to several health complications, some of which are life-threatening. Despite this, synthol is legal and easily accessible, especially online.

Synthol injections are dangerous and can lead to short- and long-term health complications
Synthol is a site enhancement oil, composed of 85% oil, 7.5% lidocaine, and 7.5% alcohol. It is injected directly into muscles to make them appear bigger. While synthol injections can lead to instant muscle growth, they come with several health risks and complications.
Firstly, synthol injections can cause muscle fibrosis, a painful and potentially irreversible condition. Muscle fibrosis occurs when the muscle tissue becomes so scarred that it dies, requiring surgical removal. This surgery is invasive and challenging, as synthol affects a broad area of muscle and tissue, making it difficult to remove without causing further damage.
Secondly, injecting synthol carries the risk of damaging nerves, which can result in permanent pain. Injection sites can also become infected, leading to redness, inflammation, and the formation of pus-filled cysts. If bacteria enter the bloodstream during an injection, it can cause life-threatening blood poisoning (sepsis). Injecting synthol into a vein or artery can result in a pulmonary or cerebral embolism (blocked blood vessels in the lung or brain), which can be fatal.
Furthermore, synthol injections do not contribute to muscle strength and only provide cosmetic changes. The synthol 'look' is often criticised for its disproportionate and unnatural appearance, resembling inflated balloons or a "condom full of walnuts."
Despite the dangers and dubious benefits, synthol remains legal and easily accessible, especially online. It is important to be aware of the serious short- and long-term health risks associated with synthol injections and to seek safe alternatives for muscle enhancement, such as strength training and dietary changes supervised by a professional trainer.

Synthol is a site enhancement oil, made up of 85% oil, 7.5% lidocaine, and 7.5% alcohol
The oil acts as a bulking agent, with sesame, walnut, or paraffin oil being the most common types used. The lidocaine, a local anaesthetic, helps to reduce pain after injection. The alcohol, usually benzyl alcohol, is meant to sterilise the mixture.
The use of synthol can lead to alarming results, with the injected muscles taking on a soft, spongey, and disproportionate appearance. The difference between real muscles and synthol-enhanced muscles is often “comically obvious” to professional bodybuilders.
Despite the risks, synthol is legal and easily accessible, especially online. Those who inject synthol may face serious short-term and long-term health complications, including muscle fibrosis, nerve damage, infection, and surgery to remove damaged muscle tissue.

It is injected directly into muscles to make them look bigger instantly
Synthol is a site enhancement oil, composed of 85% oil, 7.5% lidocaine, and 7.5% alcohol. It is injected directly into muscles to make them look bigger instantly. This process is known as "fluffing". Synthol is not a steroid and does not increase muscle strength. Instead, it is used solely for cosmetic muscle enhancement.
The oil acts as a bulking agent, with common injection sites including the triceps, biceps, deltoids, pecs, and calf muscles. Synthol injections can make muscles look disproportionately large, giving them a soft, spongey appearance.
While synthol injections can lead to instant muscle growth, they also carry significant health risks. Injection sites can become infected, causing redness, inflammation, and pus-filled cysts. If needles are reused, the risk of infection increases, and bacteria entering the bloodstream can lead to life-threatening complications such as septicaemia (blood poisoning). Injecting synthol into a vein or artery, or damaging a nerve during the injection, can have severe and potentially fatal consequences, including pulmonary or cerebral embolism (blocked blood vessels in the lungs or brain).
In some cases, synthol can cause extensive muscle scarring, which may result in muscle tissue death and the need for surgical removal. Additionally, synthol use has been linked to muscle fibrosis, a painful and potentially irreversible condition. Despite these dangers, synthol is legal and easily accessible, especially online. It is important to be aware of the serious health risks associated with synthol injections and to seek professional medical advice before considering any muscle-enhancing procedures.

Synthol causes muscle fibrosis, a painful and irreversible condition that may require surgery
Synthol is a site enhancement oil used by bodybuilders to boost the cosmetic appearance of muscles. It is composed of 85% medium-chain triglyceride (MCT) oil, 7.5% lidocaine, and 7.5% alcohol. It is injected directly into the muscle tissue to create the appearance of larger, more defined muscles. However, synthol does not increase muscle strength and may cause several health complications.
One of the most severe side effects of synthol injections is muscle fibrosis. Fibrosis causes muscle tissue to become scarred and hardened, impairing muscle function and mobility. This can lead to long-term painful muscle fibrosis and disfigurement. In some cases, the affected muscle tissue may die and have to be surgically removed.
Research has shown that synthol injections can cause severe fibrosis and recurrent infections. For example, a 45-year-old male patient presented with severe fibrosis and recurrent infections in the pectoral region following synthol injections. The patient underwent surgical removal of the fibrotic tissue under general anesthesia. Another case involved a 29-year-old Middle Eastern male bodybuilder who experienced painful pressure in his right upper arm following synthol injections. The affected muscle was surgically removed, and histopathology revealed inflammatory changes with fibrosis.
The use of synthol is dangerous and can lead to both short-term and long-term health complications. People who inject synthol into their muscles can experience pain, swelling, infections, and chronic inflammation. In some cases, the injections can damage muscle tissue and put cardiovascular health at risk. Surgery may be required to remove the damaged tissue caused by synthol injections.
It is important to note that synthol does not provide any muscle strength and is purely a cosmetic enhancement. For those seeking to build muscle strength and size safely, it is recommended to work with a trainer on a regimen of strength training and dietary changes.

Injection sites can also become infected, and if bacteria reach the bloodstream, it can lead to fatal blood poisoning.
Some people use Synthol as a shortcut to achieve bigger muscles without putting in the time and effort required for natural muscle growth. It is often used by bodybuilders who want to enhance the appearance of lagging muscles before competitions. Synthol is also driven by cultural trends, with a recent increase in usage in Latin American countries like Brazil, Argentina, and Colombia.
