The mentioned E5 plasma fraction has seemingly led to a new lifespan record for Sprague Dawley rats. "The female lifespan study, in which E5 is being tested on elderly female rats, is still ongoing because of an extraordinary fact: one of the treated rats, named "Sima", is still alive at 44 months of age. Sprague Dawley rats have a lifespan of 24 to 36 months, with specimens reaching 42 months according to some sources. So Sima, with the help of E5, is extending the limits of the maximum lifespan of Sprague Dawley rats. The study began in February 2021, when E5 started being injected in 8 female rats every 90 days, with another 8 female rats in the control group. Over time, all the rats in the untreated group died, and in the E5-treated group, all but Sima died. Additionally, Sima has not received any E5 for the last 6 months which may indicate that the benefits of the therapy can become long lasting. She hasn’t lost eyesight, hasn’t developed skin canker sores, hasn’t lost motor function or developed bald patches. Overall, the treated rats lived longer than the control ones, but it won't be possible to know exactly how much longer on average until Sima dies."
