Pinacocytes, which are epithelial-like cells, form the outermost layer of sponges, enclosing a jelly-like substance called mesohyl. Mesohyl is an extracellular matrix consisting of a collagen -like gel with suspended cells that perform various functions. The gel-like consistency of mesohyl acts as an endoskeleton, maintaining the tubular morphology of sponges.

    1. Tony Chillino – West Nyack, NY “I was skeptical at first, but I decided to go for it. The results are phenomenal. Serious Growth put 30 pounds of muscle on my frame. My strength jumped in all exercises. About 90 pounds was put on my bench, 70 on the military and back. My body went through changes that my peers couldn’t believe, they accused me of doing drugs, but I plainly said ‘never’. You’ll feel yourself growing and getting stronger during the duration of the Serious Growth training. Your body is brought to a new level of accomplishment. You’ve made my dreams come true, keep it up.”
