Nitraflex® Glycerol, Unflavored, 16 fl oz (473 ml)

I really liked the product; it provides a great pump during training and hydration.

Decided to try this brand as the one I always go for went out of stock and was more expensive. Certainly did not expect an “unflavored” version to have quite a pungent smell, but it does what it’s supposed to do. My suggestion is to mix it with something else.

Each company's product has slightly different contents, and I'm looking forward to seeing how the effects differ.

Very good product and very satisfied, very good pump, great workout, makes training fun.

Great before a workout, gives a strong boost, the quantity is excellent.

Quality, size, ingredients, hydration

The quality is good. The ingredients are glycerol. The taste is very average. The quantity is excellent. It's moisturizing. The packaging is nice. The benefit requires commitment along with exercise, fluids, and physical activity to keep the body hydrated (i.e., electrolytes).

Excellent product! Everything came well packaged, the quality did not disappoint. I will definitely repeat this order.

Very good hydration liquid. Gives you extra boost and energy. Better than the powdered form. Seems the quality is adequate but could cost less. Ingredients seem fine. The product is easy to pour into preworkout and mixes easily.

One of the best products I've ordered recently. Good quality, reasonable price and fast delivery. I recommend buying.
