Are you saying you went down to 5% natural? What did your diet look like at the time (number of calories, %protein, %fat, %carbs)?
yep.
5.0% using a 9 point skin caliper...I checked weekly and dropped roughly 0.5% each week to get there. Upper body was striated everywhere, though glutes and hams were smooth as a babies ass as typical with most natties.

15 week prep: 35 mins LI am cardio daily, 35 LI post workout cardio daily, HIIT on off days at night.
40/40/20 carbs/protein/fats, was close to 2k calories. I still use a 4/4/2 ratio, it just works well with my metabolism.
Side note: my physique and stats are NOT extraordinary for a natty. Average generics at best but I lived a bodybuilding monk lifestyle for those 15 weeks and this was the end result. Your average black teenager would "do more damage on stage" at a local natty show if they applied themselves like this.
