CTL Observation

We ran this one through multiple test sessions — it’s the real deal. The focus kicks in after 10–15 minutes, energy stays clean, and every set feels dialled in.
The Machete Melon flavour is smooth, not overly sweet, and mixes easily even in cold water.
If you train to perform, not to pose — this belongs in your gym bag.
