I depends on the test. If you're cooking Enanthate, which can literally melt in your hand, you should stay at 175deg for 10 minutes, three times. But it's rare that you'd need to do that for Enanthate.
For everything else 250deg for 10 minutes, three times is fine. You don't need to boil or melt anything. Alcohol evaporates pretty easily so heating it up a little in the oven just accelerates this process.
Some people do it one time for 20 min but my pins always melt shut when I do that.
