I'd recommend if you go the Superdrol route to keep in mind the sides that will come on as some people literally can't handle them. You WILL get a lot of size/strength gains from it considering how strong it is, If you hear of people not getting results from them they most likely have training/diet/recovery faults that should be addressed first.
Oh and you CAN stack Epi/Superdrol because they are both "absorbed" by the body differently meaning Epi binds to the adrogen receptor while Superdrol does not. SO therefor you would get extremely great results if training/diet/recovery are in the right place but you gotta remember your messing with Superdrol sides AND epi sides even though they are minimal. Having both the hormones in your body could illicit totally different side effects so the only way to know would be to start on a LOW dose and go from there! Hope this helps you out man, i'd recommend Superdrol by itself first. If you value your liver and don't take pre-cautions i'd just go with test.
If you decide to run Epi/Sdrol i would say start with this YES THE DOSAGES ARE LOW BUT IT'S BETTER TO BE SAFE THAN SORRY!
Week 1: Epi/10MG Superdrol/5MG
Week 2: Epi/20MG Superdrol/10MG
Week 3: Epi/30MG Superdrol/15MG
Week 4: Epi/40MG Superdrol/20MG
No longer than that, that is more than sufficient time for results your looking at 20Lbs lean mass no problem if diet/training/recovery is in place. That's my estimate at least, if 10MG is too much for s drol then obviously don't increase the dosage. Listen to your body!
And like i said i extremely recommend you go with 7 caps N2-Guard considering the sides and the liver toxicity along with tons of water. You will not be disappointed!
