Fast delivery
By Erro T.
Just getting started with research but so far, so good. Great product. Safely packaged. Quick shipping. Professional labeling and website along with pertinent information that a researcher needs and looks for before purchasing. Reasonably and competitively priced. A little biased here but, I like the fact that they are based out of my home state and just right up the road from my hometown.

Response from Summit Research· Apr 28, 2024
I'm sorry to hear about your experience with our B-Complex Core Energy product. We understand that it can be uncomfortable, and we appreciate you bringing it to our attention. The L-Carnitine in our formula, which is essential for boosting energy and supporting metabolism, can sometimes cause a burning or stinging sensation during injection. It's not uncommon, and we know it can be unpleasant. We're actively working to minimize these effects in future formulations.
