All synthol contains is mct oil, benzoyl alcohol, and silica. It’s nothing special. It’s a slow releasing oil. Many sponsors make their AAS with mct oil. My glutes looked like volleyballs why I put tren in them daily. Delts too. The site swelling keeps increasing if injection frequency is greater than the reduction of swelling in the tissue. Is it permanent? No. But if it’s done regularly the muscle keeps increasing in size. But like I said before, eventually it will lead to scar tissue and possible muscle necrosis. If the site injections are less frequent than the time it takes for the swelling to return to normal then it won’t cause site growth.
Also, it’s not synthol that looks fake, it’s ADE. Again, synthol is just a slow releasing medium chain triglyceride, with a minute amount of silica. ADE is permanent and gives you that ridiculous look many Brazilian wannabes have. If you have enough money to do PMMA via a cosmetic surgeon, like Rich Piana did, you can get permanent growth that looks pretty good. He spent a lot of money down in TJ regularly with a surgeon. A friend of mine looked into it. It was $4,000-$6,000 per muscle application.
