As an active user I can't say that I have, but I'm based on a different continent and use a different source closer to home. I prefer eroids as a forum and it caters for both sides of the pond and I'd maybe suggest there are better more established sources if this is your first time jumping on cycle. Research is key and I'm not assuming anything but if it is stay away from orals and run a 250-500 mg test only cycle long ester like eth or cy. As @runnerlk said focus on diet it's everything when you are on as long as your training smart. I liked the splash of SARMS but we aren't all triathletes, you say your elderly but I bet you'd kick my ass! Big respect to you. Hope that helps.
