Product Description
The burn that builds in the last reps of a hill repeat set, or in the closing stations of a HYROX race, arrives right when you still need power. This stack supports the parts of training behind that moment, from muscle endurance to energy production to power output.
Thorne's Training Stack supports energy production, muscle endurance, and power output with three products, Amino Complex (1.25 g of leucine per scoop), Creatine (5 g of creatine monohydrate), and Beta Alanine-SR (1.6 g of sustained-release beta-alanine).
Amino acid support for strength and recovery – Amino Complex supplies essential amino acids, including leucine, isoleucine, and valine, to support lean muscle mass, muscle strength, and recovery after hard sessions.
Creatine for power output and work capacity – Each scoop of Creatine supports muscle performance, strength, and power output, and it also supports cellular energy production.
Sustained-release beta-alanine for muscle endurance – Beta Alanine-SR benefits muscle output and helps reduce fatigue and soreness, with a sustained-release tablet that minimizes side effects.
Amino Complex is a vegan blend that includes the essential amino acids (the ones your body cannot make), with the branched-chain amino acids leucine, isoleucine, and valine making up the largest share. Creatine is a compound your body makes naturally and that also comes from meat and fish. Beta-alanine is an amino acid your body uses to make carnosine, a compound stored in muscle, and the sustained-release tablet releases it gradually to help minimize the tingling some people get from plain beta-alanine.
How to Use Thorne Training Stack
Dose: Mix 1 scoop of Amino Complex into at least 8 ounces of water one to two times daily, mix 1 scoop of Creatine into at least 8 ounces of water, juice, or another drink once daily, and take 2 tablets of Beta Alanine-SR one to two times daily.
Creatine timing: Consistency matters more than timing, so take your scoop at the same point each day. Thorne says you can use it 30 to 90 minutes before or after exercise.
Making it one habit: Mix the creatine into the same drink you have around training, and take the beta-alanine tablets with it.
