With just eight weeks to build muscle and burn body fat, you’ll need all the help you can get. While the RHC workout program and diet will do most of the heavy lifting—no pun intended—you’ll want some essential supplements that will speed your progress. Try the following three products in this first month:

Rock Hard Month 2 Supplement StackPro-Nos

Whey protein is the fastest-digesting protein you’ll find, and it’s also rich in branched-chain amino acids (BCAAs). Getting a quick shot of BCAA-rich protein to your muscles is critical for muscle growth, especially before and after workouts. Taking a dose first thing in the morning to counteract muscle breakdowns after your nightlong fast is also a wise idea.

Anabolic Switch

After your workouts, you’ll need another dose of creatine, taurine, and beta-alanine to restock your muscles’ levels and keep your muscle cells big and full. You also need fast-digesting carbs to enhance recovery, aid muscle growth, and drive up insulin levels. Anabolic Switch achieves this with maltodextrin. It also provides an extra dose of essential amino acids

Black Powder

This pre-workout supplement will ramp up your energy levels and provide the stamina you need to train with all-out intensity. Black Powder delivers a potent dose of arginine in the forms of L-arginine alpha-ketoglutarate and L-arginine HCl, as well as Actinos², a whey peptide fraction that leads to more arginine being converted to nitric oxide (NO).

NO2 Ripcuts

If you need a boost in fat burning during these final weeks of the RHC, add NO2 Ripcuts to your stack. This provides a number of proven fat-burning ingredients like caffeine, green tea extract, L-carnitine, Beta-phenylethylamine, and L-tyrosine. It also contains white kidney bean extract to prevent your body from absorbing too many carbs when trying to get extra lean, chromium picolinate to blunt carb cravings, and arginine to boost your NO levels.
