A compatible, biodegradable microcapsule delivery system for active ingredients, including hormonally active peptides, proteins, or other bioactive molecules, and a method of making the same. The ingredients are encapsulated in biodegradable copolymer excipients of varying mole ratios and the blend of the microcapsules are administered to an animal. Delivery of the ingredient occurs over a prolonged period of time at a constant rate as a result of the varying break-down rates of the copolymer excipients.
