Synththerol – Site Enhancement Oil (SEO) Explained
What It Is
- Category: Site enhancement oil (SEO), also called “santol” or “synthol.”
- Purpose: Injected directly into muscles to create the appearance of larger, fuller muscle groups.
- Composition: Typically ~85% oil (caprylic, capric, lauric acids), ~7.5% lidocaine, ~7.5% alcohol.
- Brand Example: Syntherol™ by Synthetek, marketed as a “fascia‑stretching” oil for bodybuilding.
Claimed Benefits (Bodybuilding Context)
- Rapid Size Increase: Can add visible inches to arms, calves, or other muscle groups within weeks.
- Fascia Stretching: Promotes expansion of muscle fascia, theoretically allowing for future growth.
- Targeted Enhancement: Used to “fill in” lagging muscle groups for symmetry.
Risks & Controversies
- Health Risks: Infections, nerve damage, pulmonary embolism, and permanent disfigurement are documented dangers.
- Cosmetic Only: Synththerol does not increase strength, endurance, or true muscle mass — it only changes appearance.
- Unregulated Use: Not approved by medical authorities; often sold online without oversight.
- Negative Reputation: Many bodybuilding federations and professionals discourage or ban its use due to safety concerns and unnatural aesthetics.
Comparison Table
| Aspect | Synththerol (SEO) | Anabolic Steroids | Veterinary Performance Injections |
|---|---|---|---|
| Purpose | Cosmetic muscle size | True muscle growth & strength | Health/performance support in animals |
| Mechanism | Oil injection expands fascia | Hormonal stimulation of protein synthesis | Hematinics, bronchodilators, recovery agents |
| Effectiveness | Visual only, no strength | Increases muscle mass & power | Improves stamina, recovery, oxygenation |
| Risks | High (infection, embolism, deformity) | Hormonal imbalance, organ stress | Veterinary‑specific side effects |
| Legality | Not illegal, but unsafe | Controlled substances | Prescription‑only veterinary drugs |
Key Takeaway
Synththerol is a bodybuilding cosmetic oil, not a veterinary medicine. It artificially enlarges muscles but carries serious health risks and no performance benefits. For your Equines Meds catalog, this product would not be relevant, since your focus is on veterinary medicines and supplements for horses, camels, livestock, poultry, and companion animals.
synththerol If you are lacking a muscle group, be it biceps, triceps, deltoids, calves, quadriceps, pectorals and any other muscle group you can think of, and no matter what else you have tried to break through the plateau to make those stubborn muscle groups grow ,and still has not worked, well then
Syntherol™ can very well be the answer!
Syntherol™, is a Site Enhancing Oil (SEO), otherwise know as
SEOs help a muscle to break past a plateau (sticking point) by helping the fascia of a muscle stretch.
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.
