I've kept gains from oral only cycles. S drol is the best muscle builder period imo. Really even if you only keep 4 or 5 lbs after a 4-6 week cycle that is still an insane amount of muscle to build in a short time. It may feel like you didn't keep much after all the glycogen fades. But yeah I'm still sticking with sdrol is the absolute fastest way to build muscle. Haven't ran it for years but used it numerous times. Ha love and hate it at the same time. Feeling like a zombie sucks but you feel like a good for that hour in the gym. Lol
