They best way to get into the swing of things with testin Putatives is to follow this post from Tisha. I am not sure why it is a sticky in the woman’s forum only, but it is the best advice to start with!
Unless you know how your daily mix works in every situation, then adding something to it may get you results, but you will not know if the p110 caused it or your mix. Thats why its best to test all by its self at first. Then add to a mix and test. Look for consistent results.
