  • Bio Synergy Performance Arginine x 125

    A killer workout starts with Bio-Synergy Arginine. With 1000mg L-arginine in each capsule, our nitric oxide boosting formula increases the volume of blood flowing to your hard-working muscles, which also increases the level of oxygen and nutrient delivery, so your muscles can work harder. In short, you’ll have more stamina and power than you normally do.

    Arginine is perfect for sports that require explosive actions, such as weight training, sprinting, boxing or crossfit. But it’s also popular with endurance athletes who want to push their stamina. That’s why you’ll find L-arginine in just about every pre workout supplement out there.

    It also helps with muscle growth because the body uses this amino acid in the synthesis of most proteins. When the size of a muscle increases, L-arginine helps to boost the release of growth hormone, which then aids in fat metabolism.

Some of the parts we sell here at Halfords have been reconditioned. These will carry a Refundable Deposit or an extra surcharge amount. When you add one of these reconditioned items to your basket, we'll add this extra cost automatically.

Once you've sent us your old item we'll check it over, and then refund you the full surcharge as long as everything is ok.

Before you return your old unit please make sure it's in re-serviceable condition. So if you're returning caliper casings, you'll need to double check they aren't badly damaged or broken. If the part you've sent is found to be unserviceable, we reserve the right not to refund the surcharge.

Please note that if you're returning your old unit to our National Returns Centre then this will be at your own expense.
