Last step in directions per

Step 5 - Filter
Filter out the testosterone propionate
as described. Let the filter completely drain, then rinse with water. Repeat this rinsing 2 more times. Now you have pure testosterone propionate, allow it to dry and it is ready for processing.
2 oz methanol not mentioned in this step. Did you mistype?
To test for purity:
There are many ways to measure melting point, but an easy way to do it at home is to put some about oil in a pan on a stovetop burner. You will need an accurate thermometer, a test tube, and a few milligrams of your crystals. Be sure you can easily tell the difference between 115 C (239 F) and 120 C (248 F) degrees, this small difference is important! Turn on the burner and heat it to about 100 C (212 F). Make sure the temp is stable. Now put the crystals in the test tube and hold this in the oil, but do not let the test tube touch the bottom of the pan. Slowly increase the heat until the crystals melt, and note the temperature. When the crystals melt at 118 C - 120 C (244.4 F - 248 F), you have pure testosterone propionate.

I did two seperate tests last night and resulted in 123C and 124C consecutively. This was done using TP from the formentioned kit. This leads me to believe that if the directions are followed properly, a highly pure product (free of estradiol) will result.
