What do you mean by outdated? M1D Andro is probably stronger and better formulated, but M1D Black is by no means terrible for what it is. It's up to you really what you want to do. M1D Black is probably really cheap at this point, so you could buy more and double the dose to 8 caps. Personally i never took less than 8 caps and was happy with the outcome. FormX you can run 4 weeks no problem. If you want to try M1D Andro, then buy that and use it.
You may be overcomplicating this a bit
