What do you mean by "gains"?
I don't know if this applies to you, but in general no one except the rank beginner is making consistent gains, doesn't matter the age. By gains I mean surpassing your past biggest ever muscular size. Most of us are in a cycle of regressing and regaining, over and over gain and every now and then we might manage to beat our best.
Lots of old timers, and younger people too, are talking about their recent gains due to new diet or training method or even drug and I'm thinking like, "man, you haven't gained shit since 1990". By gains I mean actually surpassing something, not merely regaining lost size.
Are you at your biggest and or strongest ever at this moment? My training partner was at his biggest and strongest ever at 50, after 35 years of training, but he only started juicing at 45
