Cycling is a drug. This is the supplement.
KXNGS powers top riders with its proprietary Pro Formula riding supplements and designs limited edition drops with the world's best brands, including MET and Castelli.

Pro Formula is a daily all-in-one riding supplement — two capsules, once a day. It's built for consistency: no stacks, no guesswork, just one product covering energy, endurance, recovery and sleep.

Pro Formula is built to help you train harder, ride faster, recover quicker, sleep better, reduce stress and boost immunity — designed to be the best available all-in-one riding supplement.

Most riders take four or five separate supplements. Pro Formula replaces that with one formula, meticulously crafted to deliver the utmost in quality and potency, featuring a comprehensive blend of essential vitamins and minerals crucial for cyclists. Taking it a step beyond, our formulation also incorporates patented actives, meticulously selected to elevate your performance — including KSM-66® Ashwagandha, Hydrocurc® curcumin and Lycopene, boosted with BioPerine® (Black Pepper Extract) for absorption.

Pro Formula is intended for use by adults. If you are pregnant, nursing, have a medical condition, or are taking medication, please consult a healthcare professional before use.

Store in a cool, dry place, out of reach of young children.

For best results, take two capsules at the same time consistently each day. Do not exceed the stated recommended daily dose. Most riders take it daily rather than only on ride days — it's designed to compound over weeks, not give a one-off boost.

Individual results vary, but many riders start noticing benefits such as reduced lactic acid levels, lower stress, or improved sleep after around 4 weeks of consistent daily use.

This product should not be used as a substitute for a varied, balanced diet.

Pro Formula is designed to be a complete daily formula on its own. This product is not intended to diagnose, treat, cure or prevent any disease. If you are pregnant, nursing, have a medical condition, or are taking other supplements or medication, consult a healthcare professional before use.

Pro Formula replaces multiple separate supplements with one All-In-One, custom-engineered formula, using high grade, bioavailable and patented active ingredients. Buying comparable individual ingredients separately typically costs significantly more overall — which is why Pro Formula is priced the way it is.
