I hold an unpopular opinion that less talent is associated with more drugs; so by corollary the top guys — even in sports where drugs directly enhance performance (centimeter, gram, second sports, and bodybuilding where it’s not prohibited and maximal muscle accrual is sought) — use way less than those in the lower categories. I see it applied universally.
It’s not practically easy to get 5 g of gear into you, btw, by injection. You need a decent level of muscularity to even hold that much oil. I’d call 5.7 g the practical upper limit of i.m. application anyone could manage for a SINGLE week, that’s 2 — 3 mL (less for the deltoid site, more for the gluteal), holding 200 mg/mL androgen (most gear we use is not soluble at 350 mg/mL and often as with trenbolone it’s 100 mg/mL), applied contralaterally to the gluteal, deltoid, ventroglutreal sites, in an thrice weekly rotation. That’s a metric assload of oil… and idiotic.
If anyone feels they need even half that year-round they’ve simply got to accept they need to just pick another sport… besides, at over 1.5 g weekly you’re well into the asymptotic region, and by 3 g there are absolutely negative returns.
