I like the planned next cycle brother. I am interested to see if you notice a difference between ramping test up vs just starting and staying at 500mg throughout.
If you are cruising, no need to add something else to keep gains. That should be enough. If you are losing a lot of gains, it has to do with diet. You are obviously training enough.
Get better soon man. I am currently recovering from the worst cold I can ever remember. Went to a WWE event with 50K people and knew it was likely I would get sick. Never thought it would be this bad though.
You can run that stack just fine. I prefer to run SR a few hours before training but others will tell you to space your dose out throughout the day due to the short half-life.
