5% Nutrition - 5150

Important context before anything else: 5150 is 5% Nutrition's original "Stim Crazy" high-stimulant pre-workout, supercharged with Cocoa Alkaloids and featuring 8 types of caffeine. A single scoop delivers 4g of L-Citrulline, 3g Beta Alanine, and a 500mg Stim-Crazy Caffeine Complex that includes both Alpha Yohimbine (from Rauwolfia tetraphylla, standardized to 90%) and Bitter Orange Extract (10% Synephrine) in the same serving — two distinct adrenergic stimulant compounds layered on top of a caffeine dose the label itself states is roughly equivalent to four cups of coffee. This is not a beginner's pre-workout. Start with a partial scoop to assess tolerance, and do not exceed the labeled single-scoop serving.

4g Pure L-Citrulline — Not the Diluted Malate Version

5150 uses 100% pure L-Citrulline rather than Citrulline Malate, where Malic Acid often makes up a significant share of the total stated weight. Citrulline converts to L-Arginine in the liver, promoting longer-lasting, more intense pumps than Arginine itself — at a full 4g pure dose, 5150 delivers more actual active Citrulline than an equivalent-weight Citrulline Malate product would.†

500mg Caffeine Complex From Eight Sources

The label's own warning states the recommended dose contains about as much caffeine as four cups of coffee — a genuinely substantial stimulant load. The Stim-Crazy Caffeine Complex combines Caffeine Anhydrous, Dicaffeine Malate (a delayed-release form), Theobromine, and natural caffeine from Green Tea, Yerba Mate, and Guarana, alongside Green Coffee Bean and Gotu Kola extracts. This staggered combination of fast and slow-releasing sources is designed to extend the energy curve rather than producing one sharp spike, but the total stimulant load remains significant regardless of release timing.†

Alpha Yohimbine and Synephrine — Two Adrenergic Compounds, Correctly Identified

The actual label confirms Alpha Yohimbine Hydrochloride, standardized to 90%, is sourced from Rauwolfia tetraphylla leaves — a different species than some online retailer listings state (which incorrectly cite Rauwolfia vomitoria). Separately, the formula includes 150mg of Bitter Orange Extract standardized to 10% Synephrine — meaning roughly 15mg of actual Synephrine content, not the 45mg figure some online sources report. Both figures matter for accuracy, though the underlying safety consideration doesn't change: having both an Alpha Yohimbine source and a Synephrine source in the same formula, layered on top of a 500mg caffeine complex, represents a genuinely aggressive combined adrenergic load appropriate only for experienced high-stimulant users.†

The Choline and Nootropic Stack

5150 layers three distinct choline-related compounds: 500mg of Choline Bitartrate (providing 200mg of elemental Choline, listed separately at 36% DV) and 200mg of Alpha-GPC both directly elevate acetylcholine, the neurotransmitter central to focus and mind-muscle connection, while Huperzine A (from Toothed Clubmoss, standardized to 1%) inhibits the enzyme that breaks down acetylcholine, keeping levels elevated longer. N-Acetyl L-Tyrosine (750mg) adds a more bioavailable precursor to dopamine and norepinephrine on top of this stack.†

Frequently Asked Questions

1. Is 5150 appropriate for someone new to pre-workout supplements?
   No. The label's own warning notes the recommended dose contains roughly as much caffeine as four cups of coffee, combined with both Bitter Orange (Synephrine) and Alpha Yohimbine. This formula is intended for experienced high-stimulant users, not beginners.†

2. Can I take more than 1 scoop?
   No — the label explicitly states do not exceed the recommended serving.†

3. Why does the label warn about MAO inhibitors specifically?
   The combination of Synephrine, Alpha Yohimbine, and Cocoa Alkaloids in this formula can interact dangerously with MAO/MAOI inhibitor medications, which is why the label explicitly states do not use if you are taking an MAO or MAOI inhibitor.†

4. Is 5150 appropriate for tested athletes?
   No. This formula contains both Alpha Yohimbine and Synephrine (from Bitter Orange), both prohibited by WADA and most major sports governing bodies.†
