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 Synth-Oil can very well be the answer! Synth-Oil is a Site Enhancing Oil (SEO), otherwise know as ‘synthol’. 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 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. Synth-Oil aka synthol is the reason why current top level bodybuilding competitors have achieved muscle size of which was previously unimaginable.
