The best erections I ever had were when I was using a nandrolone base with a small amount of test to keep E2 in range. They were basically diamonds, and on demand. Pretty sure most of the guys I know that have used a nandrolone based protocol also concur with improved erections. Everyone is obv different, but nandrolone is one of those compounds that is highly variable, in regards to its results and how it effects someone, based on their personal makeup, and how they’re using it. When it comes to nandrolone, u can’t ever generalize with it, in regards to how it can affect someone. Some guys it makes them feel worse than they’ve ever felt when adding it to their test based protocol, and some guys feel better than they’ve ever felt using a nandrolone based protocol, or sometimes even when adding it to a test based protocol. Some guys get ED on nandrolone, and some guys get the best erections of their life using it. And how u use it makes a big difference as well. I’m using it on top of my test based protocol atm, and erections are pretty consistently solid, but nowhere near the consistency and erection quality that I had when I was using a nandrolone based protocol. They would be like diamonds, and stay hard for literally as long as I wanted, and I could get erect very quickly whenever I needed to. So how nandrolone effects guys just depends on a lot of factors, and nobody can ever generalize with it, in regards to how guys are gonna respond to taking it
