I think it really depends on the person and how their body is handling it after all those years. My buddy in Canada, who's been bodybuilding for a while and used Steroids Canada, noticed that as he got older, he had to adjust his doses a bit, but it wasn’t drastic. His body reacted differently in his 40s compared to when he was younger, so he worked with his coach to tweak things. It’s probably smart to listen to your body and maybe lower doses if you’re feeling off, but some pros seem to keep going strong with their usual regimen.
