Dudes on a cycle with big red swollen faces and gynecomastia aren't going to run 8 minute miles. HGH maybe but that's a different class of PED for different reasons.
Also, an 8 minute mile is not a particularly high bar to clear and with the increased work capacity granted by basically every single popular steroid (funnily enough, HGH would probably not confer immediate/direct benefits in this scenario in the same way that less exotic PEDs could) it would be trivial for most users to do with little to no preparation.
