Here's a few things I found on the net:
Synthol is a SEO (site enhancement oil) used to increase the size of smaller muscles such as biceps, triceps and all three heads of the delts. This would seem similar to a breast implant to most but there is a profound difference.
There is a strong tissue that encases each muscle called fascia. It acts to contain the muscle bindles and fibers like a water balloon acts to contain the liquid. In many cases an athlete reaches a point where growth is nonexistent due to the fascia balloon being too full thus blocking further growth or expansion of the muscle. Like a water balloon fascia can be stretched. By injecting a SEO directly into a muscle belly the total volume of the muscle mass is increased resulting in a stretching effect upon the fascia. More room means a greater potential for growth.
Many doctors advise that the use of SEOs is extremely dangerous, if not potentially fatal, as injection into a major blood vessel can cause embolism, leading to heart strokes, respiratory crisis and/or permanent brain damage if SEO traces find their way into cerebral vessels.
If you always put limit on everything you do, physical or anything else. It will spread into your work and into your life. There are no limits. There are only plateaus, and you must not stay there, you must go beyond them.
