Why The Duo
Twice the Killer, 42% off.
Energy that hits like a freight train
300mg caffeine anhydrous backed by 300mg L-tyrosine. Hard, clean energy that carries the whole session — no jitters, no crash.
Pumps you can see
A full 5g of L-citrulline floods the muscle with blood and nutrients. Veins up, sleeves tight, from the first set.
Two flavours, zero boredom
Rotate Cosmic Burst and Green Goblin so neither ever gets old. Same formula, two different moods.
The final batch — ever
Killer is being discontinued. This is the last production run. Two jars now beats none later.
How to use it
Simple protocol. Brutal output.
Two jars. Two intensities. Twenty minutes to lift-off.
Start with 1 scoop
- 7.5g in 200–250ml cold water
- 150mg caffeine — judge your tolerance first
Take it: For moderate sessions and first-timers.
Two scoops on war days
- The full serving — 5g citrulline, 3.2g beta-alanine, 300mg caffeine

Your coach
Built by a man who lived the transformation
— Sky SinsKiller was the pre-workout I built for the days when I had nothing left and still had to show up. No balance, no compromise - every ingredient at the dose that actually works.
I'm consolidating the line-up, so this is Killer's final batch. Not because it failed - it's the strongest formula I've ever put my name on - but because I'd rather do fewer things perfectly.
The Duo exists for one reason: if Killer is your pre-workout, two jars now beats zero jars in October. Both flavours, 42% off, and then it's history.
