Product Description

HD Muscle Pump HD Stim Free Pre Workout is a stimulant-free pump formula built around L-Citrulline, Beta-Alanine, Creatine Monohydrate, Betaine, and Nitrosigine, with Alpha GPC, Choline, and L-Tyrosine rounding out the label. Available in 20 and 40 serving sizes, it's suited to lifters who want blood-flow and workout-feel support without caffeine. Buy it online at fuelsupplements.com with fast Canada-wide shipping.

Key Benefits

  • L-Citrulline and Nitrosigine (arginine silicate inositol) for blood flow and muscle pump support
  • Beta-Alanine included at a measured dose per serving
  • Creatine Monohydrate and Betaine Anhydrous for training performance
  • Alpha GPC and Choline Bitartrate plus L-Tyrosine for focus during training
  • Zero added stimulants — no caffeine on the label
  • Available in 20 or 40 serving formats with a 1/2 scoop or full scoop serving option

When to Use It

This is a fit for lifters training in the evening, or anyone who wants pump and focus support without a stimulant crash afterward. Because it's stim-free, it pairs well with a separate caffeine source on days you want more of a kick, or stands alone on days you don't. Beta-Alanine and Creatine are also present, so some users treat it as a daily training-day formula rather than an occasional-use pre-workout.

FAQ

Does this pre-workout contain caffeine?

No. HD Muscle Pump HD Stim Free Pre Workout is formulated without stimulants, relying instead on ingredients like L-Citrulline, Nitrosigine, and Alpha GPC.

What's the difference between the 20 and 40 serving sizes?

Both are the same formula — the container size and scoop-size options differ based on the serving size you choose (1/2 scoop or full scoop per serving).

Why these go together

Stimulant pre-workouts raise sweat rate — electrolytes protect hydration and pumps, while creatine compounds the strength work you're showing up to do.
