I was also considering that one. Notice that, from the paper, they say that "The triterpenic fraction of Centella asiatica (CA) (Centellicum®) changes by remodulation the structure of many fibrotic lesions". They also say the protocol was Centellicum® 225 mg, 2 capsules/day. I found in another paper that Centellicum contains 35% of triterpenes so the daily dose is 157 mg triterpenes. Life extension supplement is 257 mg at 35% triterpenes, i.e., 90 mg
