Biocleanse is like gold once you get it up to about 6 or 7 seconds' duration and get your Energy Regen up to 4+ per second. You can toss the green stuff all day long and still enjoy a net gain on the regen. It makes a great tool to advancing in linear missions, since you can essentially overlap and leapfrog from one cloud to the next and basically shut down the advance of all but the fastest zeds.
