Toxicity is overstated IMO. That;s with anything. If you're predisposed to high blood pressure, you may experience hypertension on cycle. If you have poor lipid profile, then a harsh oral will probably trash your lipids even more. The liver heals and regenerates as it's one of the most resilient organs in your body... It heals as long as you don't do permanent damage with ridiculously high doses for ridiculously long periods of time. If you abuse anything, it's gonna show you why it is a gamble. If you are more responsible and do your research then there's a lot of things you could do while limiting sides.
The most popular combination right now, that I can think of off the top of my head is SD bridged into Epi. Total of 6 week bridged cycle, yes harsh, yes both active steroids.. But the epi helps to dry your gains, as you would normally lose a substancial amount of water, etc during PCT. It continues providing strength gains even after the superdrol is out of your system and hardens you up.
Another option, however not considered legal, would be to stack it with a PH like xtren, which is NOT methylated and can be run at a moderate to high dose, either stacked or again bridged with the superdrol. If you are a beginner, this option may be a little much for you.
The third option is you can use an oral like superdrol to kick off a test cycle. Gains start by the time the test kicks in, and the longer time "ON" allows you to continue building, leaning out and helps accustom your body to carrying the new weight. Most people, unfortunately drop their calories too much during PCT, and a lot of it is because one of the signs of liver toxicity is that you start to lose your appetite. Unless youre running a mega dose of test, its not further hurting your liver, but increases protein synthesis, which means that you are able to consume more protein and keep your cals up.
You can run superdrol alone for good strength and lean mass gains, just know that its gonna be a little bit harder to keep your gains from a 3-4 week oral cycle because the gains happen so quickly. the last two weeks are really the only times when your body even has a chance to get used to that weight... But that's just my opinion, along with some others who will probably chime in as well..
With any oral cycle, or hell any cycle period you should have the appropriate support supps and pct items. Make sure you have EVERYTHING on hand before starting a cycle. If you get sick on cycle, try to force yourself to keep cals up, even if you are skipping a couple days at the gym. Consistency is key to keeping your gains. Good luck
