Rule One - Pump Stim-Free 270 g Powder
★★★★★— Signe B.I have used the unflavoured one when it was on sale, and it was perfect. But now I am using this flavoured one because it was on sale, so I had to take it. It contains the same ingredients as the unflavoured one but with many unhealthy additives (75g) such as blue colouring. That is why I am lowering the rating.

Description
Product Overview
Rule One - Pump Stim-Free is a powdered dietary supplement specially designed for those who want extra focus on muscle pump and blood circulation during training without adding stimulating substances like caffeine. The product comes in a convenient 270 gram tub, which is enough for many servings and makes it easy to dose as needed. Rule One Nutrition is an American brand founded with the goal of offering pure and effective sports supplements with a clear ingredient list and high quality. Their philosophy is based on transparency and developing products that support performance without unnecessary additives.
What makes Pump Stim-Free particularly interesting is its focus on providing a powerful pump experience and increased blood flow capacity without stimulation, which is perfect for those who want to avoid caffeine or other nervous system stimulants but still maximise their training experience.
Active Ingredients & Science
This product contains, among other things, citrulline malate, known for its good bioavailability and ability to contribute to increased nitric oxide production in the body, which can help improve blood circulation. It also includes betaine, a natural substance linked to cellular fluid balance and muscle volume. The formulation is carefully composed to ensure that the ingredients are in forms that are efficiently absorbed without unnecessary fillers.
Benefits & Uses
- Optimises muscle pump during training without stimulation from caffeine or other nervous system stimulants.
- Ideal for those who train late in the day and want to avoid sleep disturbances.
- A good choice for people sensitive to stimulants but who still want the benefits of increased blood flow and muscle volume.
- Easy to mix in water or any preferred drink, making it convenient to take to the gym or use at home.
- Can be combined with other supplements, such as creatine or protein, for a complete training routine.
Usage & Dosage
The recommended dosage is one scoop (approx. 9 grams) mixed in 250-350 ml of water, about 20-30 minutes before training. The product can be taken on an empty stomach or with a light snack depending on what feels best for you. Avoid exceeding the recommended dose to ensure optimal effect and avoid discomfort. For best results, Pump Stim-Free can be combined with other Rule One products but should not be used together with other stimulants.

The products are carefully tested for purity and content, without unnecessary additives or artificial colours.
