Revolution formula stallion extender is a great general-use sugar and milk-based extender formula. The extender arrives as two components – the foil packet of dry powdered extender mix and the premeasured bottle of sterilized water. The combined components produce 100ml of extender. Revolution is available in multiple antibiotic options (and in each version including antibiotic, the antibiotic powder is mixed directly into the powdered extender formula, eliminating the necessity for an extra mixing step). Revolution with Amikacin & Potassium Peniciliin (K-Pen) is the most popular version of the extender, but it is also available with Ticarcillin, Gentamicin, or without antibiotic. We also offer the Amikacin & K-Pen formula in a 150ml size.
