Where are the ancillaries? You need to keep estrogen under control during the cycle, and the best thing for this would be aromasin taken at 10 mgs EOD from the first day of the cycle. Then come the orals - they are liver toxic, so you need to use a good liver supporting supplement, such as n2Guard.
As for HCG, I would not use it, neither on cycle, nor off cycle, since its benefits are definitely not worth all the risks. It can cause such side effects as gyno and suppression, and it will barely do anything for your natural testosterone production. In fact, it only mimics the functions of LH and FSH, but it will not actually make them work. As a result, you will get an increased level of testosterone only while you take HCG, which will drop back down as soon as you stop using it. Therefore, it would make sense to use something that will cause less side effects and actually do something for your natural testosterone production. For instance, you can use HCGenerate ES - it will keep the plums big and functioning during the cycle, and it will be a great help for natural testosterone production during PCT, since it will make LH and FSH actually work. As a result, your body will keep producing testosterone even after you stop taking it. However, unlike HCG, it will not cause any side effects at all, and it is more convenient, since it is taken orally. Besides, the libido boost from HCGenerate ES is a sight to see.
Finally, your PCT is extremely weak. If you want to have a smooth and proper recovery, which will allow you to maintain the gains made on cycle, you need to run a more comprehensive PCT, such as the protocol described here -
