The German retailer Gigas Nutrition, like many other supplement stores in Europe, has its own line of products under the name GN Laboratories. While it has been quieter in recent years, back in the day, that brand pumped out some serious formulations, especially in the pre-workout category. There was a string of years where GN dropped special edition pre-workouts around FIBO that were rated some of the best in the world, like T1 Virus, Narc Nemesis, and Narc Infection.
This year, Gigas Nutrition and GN Laboratories have decided to bring back or relaunch the long-running supplement Narc, and like those pre-workouts of the past, it is stacked. The team behind the retailer and brand has put its formulation ability on full show once more with a comprehensive combination of ingredients and dosages for increased energy, focus, pumps, and a lesser portion dedicated to performance.
Taking care of the muscle pumps in GN Laboratories’ 2026 edition of Narc is 2g of GlycerPump glycerol, 6g of citrulline malate, and 4g of arginine HCl. Alongside the trio of pump components is bitter orange, 300mg of citicoline, schisandra, theobromine, n-acetyl-l-tyrosine, and a potent 400mg of caffeine to ensure intense energy and focus. It’s all topped off with the ever-present AstraGin at 50mg to get the most out of the formula and maximize efficacy.
Simply put, GN Laboratories and its long-running stimulant pre-workout Narc are back in business, and with a pretty robust blend of ingredients and dosages. We also like that it’s stuck to its own approach, not necessarily including go-to features like creatine and beta-alanine, and is driven hard on focus and pumps in addition to the energy. The product is now available straight from Gigas Nutrition, and the price is not too bad considering the reputation Narc has at €39.96 (47.22 USD).
