Description

Trained By JP Sustain – Elite Intra-Workout Carbohydrate Powder

Trained By JP Sustain is our elite intra-workout carbohydrate powder, built for hard training sessions and sporting events where physical demand is extremely high, long in duration, or extended over a full day.

The Carbohydrate Source

Sustain’s carbohydrate source is patented cyclic dextrin, which digests extremely well even in those with sensitive stomachs — avoiding the bloating and gastric distress that standard maltodextrin-based carb powders commonly cause during a hard session.

Pharmacy-Grade Citrulline

Alongside the cyclic dextrin, Trained By JP Sustain uses pharmacy-grade Kyowa Citrulline — the highest quality citrulline available on the market — rather than a generic, unverified source.

Hydration and Recovery Support

To aid cellular hydration and recovery, Sustain includes Sustamine, a pharmacy-grade version of Alanyl L-Glutamine. On top of this, Sustain contains a carefully balanced blend of electrolytes and alpha lipoic acid to support carbohydrate uptake and rehydration during long or demanding sessions.

How to Use Trained By JP Sustain

Mix a serving with water and sip consistently throughout extended training sessions or sporting events. Adjust serving size based on session length and intensity.

Buying Guidance: Sustain vs Standard Intra-Workout Carbs

Sustain is built specifically for extended, high-demand sessions — endurance events, multi-hour training blocks, or full-day sporting competitions — rather than a standard hour-long gym session. For shorter sessions, a standard intra-workout carbohydrate product is usually sufficient; Sustain is the step up for genuinely elite-level demand.

Frequently Asked Questions

What makes Sustain different from a standard intra-workout carb?
It’s built specifically for extended, high-demand sessions, combining patented cyclic dextrin, pharmacy-grade citrulline and Sustamine rather than a single carbohydrate source alone.

What is Sustamine?
A pharmacy-grade version of Alanyl L-Glutamine, included to support cellular hydration and recovery.

Is Sustain suitable for a standard hour-long gym session?
It’s designed for extended or higher-demand sessions; a standard intra-workout product is usually sufficient for shorter training.

Why is Kyowa Citrulline used?
Kyowa is a pharmacy-grade citrulline source, chosen for quality over a generic, unverified alternative.

Race-Day and Event Nutrition Planning

For multi-hour events or competitions, Trained By JP Sustain is designed to be used alongside a broader carbohydrate strategy rather than as the sole source of fuel. Many athletes find it useful to combine an initial serving in the hour before the event with smaller top-up servings spaced through longer sessions, adjusting concentration and volume based on gut tolerance and the intensity of the session. Because cyclic dextrin has a lower osmolality than standard maltodextrin, it can typically be mixed at a higher concentration without the same risk of gastric distress, giving more flexibility over how much carbohydrate is consumed per serving.

Flavours Available

Trained By JP Sustain is available in Berry Burst and Orange & Mango, both formulated to be easy to sip consistently across a long session rather than becoming sickly at higher concentrations — an important consideration given how much of this product is typically consumed across a multi-hour event.

Storage

Store in a cool, dry place away from direct sunlight, with the lid firmly sealed between uses to protect the powder from moisture and preserve the potency of the electrolyte and amino acid content.

Complete Your Intra-Workout Stack

Pair Sustain with Trained By JP EAA for additional essential amino acid coverage during particularly long or demanding sessions.

Who Shouldn’t Use Sustain

If your training rarely exceeds an hour, Sustain’s cost and formulation are built for a level of demand you likely won’t reach — a standard intra-workout product will serve you better and more cost-effectively. Sustain earns its place specifically for multi-hour, elite-level output.

Food supplements should not be used as a substitute for a varied, balanced diet. Do not exceed the recommended daily intake. Keep out of reach of children. If you have any health concerns or are taking any medications, please speak with a healthcare professional before use.
