Most "pump" products are powders loaded with stim, sweetener, and 6g of L-citrulline. N.O. Boost is a stim-free capsule designed to stack with whatever pre-workout you already use — 800mg L-Arginine (400mg free-form + 400mg AKG 2:1 extract), 400mg L-Citrulline (200mg free-form + 200mg malate), 80mg Beta-Alanine, and 30mg Niacin.
Capsule format means no extra scoop in your shaker, no taste to dial in, and it can ride alongside PERFORM, PERFORM Non-Stim, or a coffee. Two capsules, 20–30 minutes before training, with 8 oz water. 30 servings per bottle.
- ✓800mg L-Arginine (free-form + AKG) — supports normal nitric oxide production and blood flow to working muscles
- ✓400mg L-Citrulline (free-form + malate) — converts to arginine for sustained nitric oxide support
- ✓80mg Beta-Alanine — supports normal intramuscular pH buffering during high-intensity sets
- ✓30mg Niacin (150% DV) — supports normal vasodilation and the visible "flush" feel

Is this right for you?
- ✓You want pump and blood-flow support without another scoop in your shaker
- ✓You already have a pre-workout you like and want to stack a stim-free pump enhancer on top
- ✓You train high-volume hypertrophy work where pump and acid-buffering matter
- ✓You like the convenience of capsules — no taste, no mixing, no flavor fatigue
- ✗You have low blood pressure or take blood-pressure medication — vasodilators can compound the effect
- ✗You take ED medication (sildenafil, tadalafil) — both work via the same NO pathway, consult your physician
- ✗You're pregnant, nursing, or under 18 — consult your physician first
- ✗You want a high-dose 6g+ citrulline pump powder — N.O. Boost is a stack-on capsule, not a standalone megadose
How to use it
Pre-workout: Take 2 capsules with 8 oz water 20–30 minutes before training. Stack with your usual pre-workout, coffee, or PERFORM.
Daily option: Take 2 capsules once a day, ideally before a meal, to keep arginine/citrulline available on rest days. Don't exceed one serving per day.
One bottle = 60 capsules = 30 servings = 30-day supply.

Frequently asked questions
How is N.O. Boost different from PERFORM?
PERFORM is a full pre-workout powder with caffeine, beta-alanine, and citrulline at higher doses. N.O. Boost is a stim-free capsule for pump support — designed to stack on top of PERFORM, coffee, or used alone on lower-intensity days.
When should I take it?
20–30 minutes before training, on an empty or light stomach, with 8 oz water. The arginine and citrulline need a window to convert and circulate. On non-training days, take with a meal in the morning if you want continuous availability.
Can I stack N.O. Boost with other MaxWell supplements?
Yes. The pump stack: Organic Beetroot for additional dietary nitrate, PERFORM pre-workout for stim and citrulline, and EAAs + Hydration intra for amino acids and electrolytes.
Should I worry about blood pressure or interactions?
If you have low blood pressure, take blood-pressure medication, or take ED medication (sildenafil, tadalafil), consult your physician first. All of these work through the nitric oxide pathway and can compound. Healthy adults with normal BP rarely have issues at the listed doses.
