About Performance Lab Stim
Performance Lab Stim is an energy supplement. Part of the Performance Lab sub-brand, the product is made by Opti-Nutra. It was created to provide “cleaner, calmer and healthier stimulation”.
This product contains seven ingredients. These include natural caffeine, which is said to enhance performance. The manufacturer says it uses a relatively low amount of the stimulant (50mg) to improve “caffeine intake control”.
Meanwhile, L-theanine is thought to work alongside caffeine to promote a calm alertness.
In addition, L-tyrosine could help improve working memory, multitasking and the ability to think “under fatigue”.
There are 30 capsules (30 servings) in each bottle of Performance Lab Stim.
