<p style="font-size:19px;color:#5c6b6b;margin:0 0 20px">That brief flushing, itchy, tingling feeling after a pre-workout is called paresthesia. It’s caused by beta-alanine, it’s harmless — and here’s why Antidote dosed it for daily use, not maximum tingle.</p>

It typically lasts ten to thirty minutes and fades. It simply means beta-alanine is in the formula and being absorbed.</div>

<p>If you’ve taken a pre-workout in the last decade, you’ve probably felt it: a strange tingling — sometimes prickly, sometimes mildly itchy — washing across your face, neck, and forearms about ten to fifteen minutes after dosing. For some it’s pleasant; for others it’s like a brief case of pins and needles. It’s one of the most-asked-about and least-explained side effects in the category.</p>
<h2>What causes the tingles in pre-workout?</h2>
<p>Beta-alanine, an amino acid that activates specific nerve receptors in the skin called MrgprD receptors. When it binds to them, the nervous system reads the signal as a mild prickling or flushing sensation. The medical term is paresthesia. It’s not a histamine or allergic response — it’s the predictable result of beta-alanine reaching skin-surface nerve receptors faster than the body can process and store it. Intensity varies a lot between people and tends to be strongest in first-time users.</p>
<h2>Is beta-alanine safe?</h2>
<p>Beta-alanine is one of the more thoroughly studied supplements in sports nutrition. The International Society of Sports Nutrition’s position stand concluded that daily intakes up to 6.4 grams are safe for healthy adults across multiple weeks of use, with paresthesia as the most common and benign side effect. Two caveats: people with kidney conditions or histidine-metabolism issues should consult a physician before any amino acid supplement, and some users simply find the sensation unpleasant — a reasonable preference.</p>
<h2>Why does Antidote use beta-alanine at all?</h2>
<p>Because it has repeatable performance research behind it. Beta-alanine combines with histidine in muscle to form carnosine, which buffers the buildup of hydrogen ions during intense exercise — one of the mechanical causes of the burn and performance drop-off during sets lasting 60 to 240 seconds. More muscle carnosine means greater capacity in that window: an extra rep or two on high-volume sets, and measurable benefit for CrossFit, HIIT, rowing, and running. Carnosine accumulates over weeks of consistent intake, not on day one — by weeks four to eight of daily use it should be measurable.</p>
<h2>Why 2 g, and why not dose for maximum tingle?</h2>
<p>Antidote uses 2 g (2,000 mg) per scoop. The clinical range for maximizing carnosine is 3.2 to 6.4 g/day, but lower doses still build carnosine meaningfully over time. We chose 2 g for three reasons: the effect compounds with daily use (we build for the third-tub user, not the first-tub impression); paresthesia intensity scales with dose, so 2 g stays mild and manageable; and users who want more can easily titrate up. Dosing beta-alanine high enough for a dramatic full-body tingle is a marketing choice — it gives an “I can feel it” signal that drives reorders — but it doesn’t deliver meaningfully more performance over time.</p>
<h2>Will the tingles go away over time?</h2>
<p>For most users, yes — paresthesia diminishes with regular use as the nervous system adjusts. By the second or third week of daily use, most people report the tingle becoming subtle or fading entirely. If it stays strong, splitting the scoop (half fifteen minutes before, half thirty minutes before) lowers the peak concentration, and taking Antidote with a small snack slows absorption and mellows it further.</p>

<h2>Frequently asked questions</h2><h3>Is the pre-workout tingle dangerous?</h3><p>No. It’s paresthesia, caused by beta-alanine activating skin nerve receptors — not an allergic reaction, nerve damage, or a sign the dose is too high. The ISSN position stand confirms the sensation is benign.</p><h3>How long does the tingle last?</h3><p>Typically ten to thirty minutes, peaking around fifteen minutes after dosing.</p><h3>Does the tingle mean the pre-workout is working?</h3><p>It confirms beta-alanine is present and absorbing, but it doesn’t measure performance benefit — that accumulates over weeks as muscle carnosine builds.</p><h3>How much beta-alanine is in Antidote?</h3><p>2 grams (2,000 mg) per scoop — below the upper clinical range but enough to build meaningful carnosine over weeks of daily use.</p><h3>Why doesn’t Antidote dose beta-alanine higher?</h3><p>Because the long-term performance curve is gradual while the paresthesia curve is steep. We optimized for sustainable daily use rather than a strong first impression.</p><h3>Can I stack additional beta-alanine with Antidote?</h3><p>Yes. Many lifters add 1–2 g of standalone beta-alanine on training days to push toward the upper clinical range, well within established safety thresholds.</p>

Antidote uses 2 g of beta-alanine built for a pre-workout you can take five days a week for years — not for a one-time flush. <a style="color:#ffffff;text-decoration:underline" href="https://antidote-life.com/products">Try a tub.</a></p></div>
