Yup, works well, I have clients doing 15mg tbol pre workout and 15mg of anavar post workout. It drives anabolism through working on different receptors. Remember you are trying to cover all the types of compounds used for maximum synergy. 200mg of test, 200mg deca and 200mg masteron will work better than 600mg of test alone for this reason.
Tbol gives you great strength, and then anavar is better for driving recovery. It works well.
Anadrol and mk is probably the worst idea due to 1 being a dht and 1 being a secretealog how ever they both drive up water retention like a mother fucker. So unless you want BP issues then that is going be an issue.
Remember every drug has an application. Using mk677 for rem sleep happens at 2.5-5mg. To drive appetite you are using 20-25mg. Anadrol is great for strength but the appetite suppression is horrid, so for me, it makes no sense to use anadrol for bulking more so as a start to a cutting cycle when you are trying to keep hunger down but strength up. Off season when you are trying to drive strength aswell as good quantities up for maximum anabolic effects anadrol will do 1, but you will battle to get all your food in. So in that setting not a great drug, IMHO at least.
Also pre contest, 4 orals get used mostly. Anavar, winstrol, halo and even superdrol and majority of those are stacked together.
Remember, Broderick is a biologist with a propensity for studying anabolics, so he wouldn't put out info if it wasn't sound with practical application.
