Beau, in terms of progesterone, I've only used crinone or pessaries. The only alternatives I know are oral (inefficient and prone to more s/e) or injections (very, very expensive, from memory, and painful). An alternative form of luteal support is hcg booster shots - the hcg encourages your body to produce its own progesterone, thus reducing (or eliminating) the need for progesterone supplementation.
