They are right. Test e should be injected E3D or twice a week at least to keep serum levels steady. Once a week is less than optimal and will create more fluctuation as well as prolonging the time required to get your blood level up to the desired cycle level.
Your dose of Adex does sound a little high, however each person responds differently. If the dose is really too high, then in addition to lack of libido, you should have achy joints - possibly knees, mental fogginess, and feel like general crap. If you are feeling those symptoms stop the Adex fpr about a week for serum level to fall and then resume at about 0.2ml EOD. You can even continue an even smaller dose of 0.5mg/w in split doses throughout PCT and after PCT to keep estrogen in check.
I don't know about your weighing system. How does one weigh liquid? I use the dropper although it is not extremely accurate for very small doses. You can use a 1 ml barrel as an oral syringe and improve on accuracy. Remove the needle. You should be able to re-use the same barrel for many doses - just push some water through to clean.
