Buy Synththerol
Synththerol (often confused with Synthol) is an injectable site‑enhancement oil (SEO) used by some bodybuilders to artificially increase the size of muscles. Unlike anabolic steroids, it does not build real muscle tissue or strength. Instead, it is injected directly into muscle groups (commonly biceps, triceps, deltoids) where it creates a swollen appearance. The compound is typically made of 85% medium‑chain triglyceride (MCT) oil, 7.5% lidocaine, and 7.5% alcohol.
What Synththerol/Synthol Is
- Purpose: Cosmetic muscle enlargement, not performance enhancement.
- Mechanism: Oil remains in the muscle, stretching tissue and giving a “pumped” look.
- Difference from Steroids: Steroids stimulate protein synthesis and real muscle growth; Synththerol only inflates muscle volume.
Risks & Dangers
- Muscle damage: Can cause fibrosis, nerve compression, and tissue necrosis.
- Cardiovascular risk: Oil embolisms can travel to lungs, brain, or heart, leading to life‑threatening complications.
- Permanent disfigurement: The injected oil can harden, requiring surgical removal.
- Infections: Non‑sterile injections may cause abscesses and sepsis.
- Unnatural appearance: Muscles look swollen but lack definition and strength.
Comparison Table
| Feature | Synththerol (Synthol) | Anabolic Steroids |
|---|---|---|
| Effect | Cosmetic swelling, no strength gain | Real muscle growth & strength |
| Composition | MCT oil, lidocaine, alcohol | Hormonal compounds (testosterone, etc.) |
| Duration | Semi‑permanent, may require surgery to remove | Temporary, depends on cycle |
| Risks | Tissue necrosis, embolism, infection | Hormonal imbalance, organ strain |
| Legality | Often unregulated, but risky | Controlled substances, medical uses |
Legality & Use
- Not approved for medical or veterinary use.
- Banned in competitions: Bodybuilding federations prohibit Synthol/Synththerol use.
- Unregulated market: Often sold online without medical oversight, increasing risk of contamination.
Key Takeaway
Synththerol is not a safe or legitimate performance enhancer. It is a cosmetic oil injection that can cause serious health risks, permanent damage, and disfigurement. Medical experts strongly advise against its use, and it is not recommended for athletes or general health purposes
The fascia is the sheath of tissue that envelops a muscle. It is also the primary restrictive factor in muscle growth.
The more flexible the fascia is, the quicker the muscle size will increase. If you see top professional bodybuilders that have muscle gropus that ‘pop’, they have very flexible muscular fascias.
When proper protocol is used as described in on small muscle groups such as the arms, gains up to 3″ in 30 days are not uncommon, and if proper protocol is followed, the size will become permanent.
aka synthol, is the NUMBER 1 CHOICE OF PROFESSIONAL BODYBUILDERS and top amateur competitors.
is the reason why current top level bodybuilding competitors have achieved muscle size of which was previously unimaginable.
As the size of their muscles increased it also became common knowledge that a lot of this size was attributed to the use of Site Enhancing Oils.
is the number one selling Site Enhancing Oil in the world, is even supported by Chris Clark himself, the inventor of SEOs and synthol, as mentioned in his latest book.
