Recovery is critical when you’ve been pushing your body to its limits, which is why we’ve created a post-workout that features lab-tested ingredients to help your body recover and repair. Our Lab Series After Build®includes creatine to help your muscle cells regenerate ATP, which in turn increases your muscles’ capacity to do work. It also has betaine, which reduces muscle breakdown and promotes muscle growth. And, it packs a whopping 6g of BCAAs, known to help stimulate muscle growth. Really, all of this means better recovery in less time, with support to keep your muscles supple, healthy and primed for your next workout.


After Build® is perfect for active men and women looking to maximize their frequency and intensity in the gym by improving their recovery.


MuscleTech® researchers have partnered with the Faculty of Kinesiology of the University of Toronto – an institutional leader with a long history of innovation and research – to support the MuscleTech Metabolism and Sports Science Lab. MuscleTech Lab Series products are based on research from universities and third-party labs all around the world, including emerging research from the Metabolism and Sports Science Lab for trusted results.


  • Only the highest quality ingredients
  • Key ingredients backed by real scientific research
  • Fully disclosed formulas
  • Clinically dosed, lab-tested key ingredients


2.5g Betaine


Researchers have put betaine to the test and the results are incredible – making it a must-have supplement for anyone serious about building muscle. In one gold-standard clinical study, test subjects who supplemented with the exact 2.5g dose of betaine found in 1 scoop of After Build® built 3.75 lbs. of lean muscle in 6 weeks compared to 0.66 lbs. by the placebo group. What’s more, test subjects actually increased arm size, as measured by a cross-sectional area (49.5 to 54.1 cm)!2

In a separate study, this same dose helped subjects significantly enhance their muscular endurance.

6g Creatine Mono & HCI


Creatine has been extensively researched for its benefits in increasing muscle strength and power and enhancing recovery during training. Research published in the Journal of Applied Physiology found that a dosage of 3g of creatine daily for about a month is required to saturate muscles, resulting in increased muscle strength, increased performance and enhanced muscle size. Many recovery products include less than this ideal amount! With After Build®, you get a full dose of creatine in the form of ultra-pure, HPLC-tested creatine monohydrate and creatine HCI.

After Build also features a 2g dose of glutamine to help restore plasma glutamine levels that may have been depleted after periods of intense training.

3g BCAAs


Lab Series After Build® is packed with 6g of 100% free-acid BCAAs – including the clinically studied 4g dose of highly anabolic leucine.

Leucine is a key dietary amino acid that has the capacity to stimulate muscle protein synthesis. It does this by stimulating your body’s master protein synthesis regulator, mTOR. Each scoop of After Build is packed with 4g of leucine, and this 4g dose is the exact amount of this highly anabolic amino acid shown in a clinical study to help subjects increase their 5-rep max strength by over 40% in 12 weeks!

This study was published in the International Journal of Sports Physiology and Performance. Read the full research paper: Ispoglou et al., 2011. International Journal of Sports Physiology and Performance. 6(1):38–50.

What’s more, in a separate gold-standard clinical study, the 1g dose of taurine found in After Build was shown to improve performance in endurance athletes.

This study was published in the journal Amino Acids. You can check out the full research paper here:
