GNC AMP - Men's Strength Vitapak® Program

  • Get Stronger & Help Build Mass: GNC AMP Men’s Strength Vitapak® Program features a clinically studied creatine and includes Testofen®⬩*.
  • Clinically Proven Multivitamin Blend: Our multivitamin blend is clinically proven to work better than a basic multi at boosting levels of key nutrients that support energy production and immune health^.
  • Move 9.5 Times More Weight: Every pack includes Creatine HCl 189™, which is shown to increase strength and performance with ¼ of the dose compared to creatine monohydrate*⬩†⬦.
  • Get Primed For Results: Increase athletic performance and come back ready to train with a blend of Testofen and support for a healthy inflammatory response*.
  • Protect Your Muscles: Clinically researched antioxidants defend against free radicals caused by intense workouts*.
  • Convenience & Value: Provides 3 products-in-1 at a better price than buying each separately. The daily packs are individually wrapped, making them convenient and easy for on-the-go.
  • Quality You Can Trust: Gluten free. No artificial flavors. No dairy. Contains clinically studied ingredients.
  • How To Take: Take the contents of one pack daily with food. Do not take prior to bedtime.


^In a randomized, double-blind, placebo-controlled study of 112 healthy participants, those taking the GNC vitamin and mineral blend for six weeks had statistically significant increases in serum levels of a group of B vitamins and a group of antioxidants and carotenoids based on a multivariate statistical analysis when compared to those taking placebo or a basic multivitamin.

⬩In a randomized, double-blind, clinical study of 57 healthy, young adult males, subjects who took GNC AMP Creatine HCl 189TM containing only 1.25 grams of the PEG-Creatine SystemTM significantly improved leg press 1-RM performance by 54.3 pounds, while subjects receiving 5 grams of creatine monohydrate significantly improved performance by 52.3 pounds and the placebo group showed no significant improvement at 5.7 pounds at the end of the study.

⬦In a clinical study of 17 healthy young adults, muscle biopsy results revealed that GNC AMP Creatine HCl 189TM resulted in 189% greater muscle creatine uptake relative to benchmark amounts of ordinary creatine monohydrate powder.

†When used in conjunction with regular resistance training.
