Biggest things are cardio and insulin sensitivity. Get in more than 30min of cardio a day (5 days a week), just just 20.
As for insulin sensitivity:
When an AAS abusing athlete drops dead of a heart attack, I believe the thing that is the cause for at least a significant fraction of these types of sudden deaths is hyperkalemia. HGH and slin is more and more popular. Reckless cycles are still just as prevelant. So when you combine HGH & Slin, plus more than a gram of gear, plus orals with no cardio, and a huge caloric intake, you develop insulin resistance fast. Also cramping is common, and people say take taurine and potassium. Well, when you take Telsmarten and a beta blocker, both of those increase retention of potassium, blood levels rise. When you get insulin resistant, blood potassium levels rise. When you supplement potassium, blood levels rise. So now you are hyperkalemic as fuck due to the BP meds, plus the HGH induced insulin resistance, and you are supplementing potassium for your cramps, which is being caused by potassium not entering the muscle cell due to insulin resistance. You then unknowingly develop a fatal arrhythmia and boom your dead. I basically did all the above, minus dying, because I was able to put 2 and 2 together after I started getting chest pain at the end of my cycle. Got a blood test, and my potassium was 16% over the upper level a week after I stopped my cycle and stopped hgh.
Take ALA, and berberine on carbby days, bike your ass off.
If insulin sensitivity is in order, then Proactive BP meds use is advised. Sitting down at the end of the day, after work, relaxed, and THEN taking BP is not the most accurate reflection of your daily BP. Taking the minimum dose of Lisinopril or Telmisartan is smart unless it is truly making you hypotensive.
Fish oil, NAC, and TUDCA (when needed). And running some sr9009 to help improve lipids after an oral run. 2x a day dosing prevent plaque build up in arteries, rapidly improves lipids, and prevents heart remodeling.
