On top of the Hawthrone Berry, make sure you're preloading Milk Thistle as well, very important. It's really up to you, if you want to stack just make sure you're extra covered with protection; however, if you plan to save tren+epi and use that at a different time, that's also a good idea. I'll outline a couple of things for ya.
To eliminate some of the sides on SD would be a test base product that we highly suggest (dermacrine/transderm). St johns wort helps lethargy; as mentioned take 2x to 3x the recommended doses. Vit C start with 3g and slowly work your way down and that will help with stress. Also be sure to keep active, even on non workout days and that will help out as well. B12 will give ya energy and will help out with your mood as well.
Get an organ shield/cycle assist + a good multi like Orange Triad (this will have joint supplement ingredients as well) or Vital Core (this will have great liver antioxidants and protection); since you already have liv 52, I'd still suggest vitcal core and get a joint supp such as forged joint repair or something similar to this (amazon, drugstore, etc). Even though it's been a couple of years, I'd still suggest keeping an eye on your BP and cholesterol; machine and bloodwork. Be sure to drink at least 1.5-2gallons of water a day and of course eat cleanly as possible. What's your diet lookin like if you don't mind me asking.
If you're going to run SD solo, you're doses look fine at 20/30/30/30, just listen to your body, if it gets too intense don't be afraid to drop it back a bit. Make sure you space your SD doses and cycle assist, multi and other supps, by at the very minimum 4 hours; however, you can take fish oil with your sd; I wouldn't go past 4 weeks of SD either.
I will say that's pretty damn crazy your last cycle with a proper pct and I trust you've done some bloodwork or that you plan on doing some bloodwork sometime in the future; however, next time don't trust the wrong ppl and don't feel embarrassed to ask anything that's on your mind; because if it's in your body fand you're getting the wrong advice then doing the wrong thing, that's gonna lead to a lotta trouble. However, this time do a proper pct for 4 weeks, you're pretty much covered in your PCT. To be on the safe side, I'd throw in one more test booster like unleashed/forged pct/testopro and looks like you'll pretty much be covered. Also, to prevent certain other sides get in a good source of B6/B12.
I think you're just about there, take those things into consideration and let us know what you plan on doing bro. If you have any more questions or need more explanation on certain things, type it in and we'll sort ya out.
