This is a review of the NDS Nutrition SirenLabs Shok’d V2- Strawberry. The manufacturers claim that it is designed to pump strength, energy and endurance into your workout. It is reputed to have an invigorating sense of satisfaction when you take it during your pre-workout. The basic element of this product is nitric oxide which is meant to give you a vigorous “pump” effect during and after your workout.

Read on to learn about its ingredients and our opinion of whether this is the right product to take for your health supplement needs.

There is no mention of a guarantee for the product on the website.


This product seems to be of great use when it comes to pre-workouts. It has minimal ingredients than most of its fellow pre workout products on the market and the feedback from different reviewers is good.

However, the side effects section can cause any customer to be alarmed. It looks as though not too many people can enjoy using this product without worrying about a ton of cautionary issues related to the consumption of SirenLabs.

Another discouraging factor about SirenLabs is that the price of the product is quite high. Seventy four dollars and some change is money that the average consumer may not want to part with, even with all the benefits this product’s manufacturers claim the product has.

Last but not least; When a product does not come with any form of guarantee, then it is impossible to go any further in considering to purchase the supplement.
