God no. More like a never-ending lean bulk.
My genetics are good too, both my parents have athletic bodies at 50+ yo.(Dad's on trt tho)
I got 17 kg in two years and that is not such of an exceptional gain, but keeping my bf below 12% all the time made the result come reeeeeal slow. Also, i started at 108lb/1.74m so i was a horrendous twig.
