A precise read on how much fluid and sodium you lose when you train, so you can stop guessing at your hydration strategy and start dialing it in.
What it consists of:
• Pilocarpine iontophoresis: mild electrical stimulation on your forearm induces localized sweating in about 5 minutes. No needles, no blood draw, not painful — it’s the same goldstandard method used in clinical sweat diagnostics.
• A sweat sample is collected via a small patch worn on your forearm, typically taking 5–20 minutes depending on your sweat rate.
• About 45 minutes total, including a full discussion of your results.
What you get :
• Your individual sodium loss rate (mg/L).
• A personalized fluid and electrolyte plan for training and race day — how much to drink and how much sodium to replace, before, during, and after effort.
After checkout: our team will reach out ASAP to get your test scheduled at a time that works for you.
