Over the last two years I've tried putting on weight to only end up fat again whilst changing my routine periodically and autisticly following both my diet and routine, now as a skinny fag who might be stronger than your average normie but still is weak as fuck, I've decided it might be worth it to turn in my natty card.
Of course, my decision isn't baseless, for one, you will never get big as a natty. You might look decent but never big.
Second, simply injecting yourself with a moderate dose of testosterone will make you bigger while doing nothing but eat than your natty self trying his best (Source: https://www.nejm.org/doi/full/10.1056/NEJM199607043350101)
Third, the number of my age might grow, but my test levels aren't. If I want to keep a healthy Testosterone level I'll be forced to inject myself.
Tl;DR Natty liftings benefits are very slim, injecting yourself after learning how to properly eat and lift is far more beneficial.
