I'm really liking the after burn in the evenings. It helps with digestion and doesn't effect my sleep. Been taking HMB for about 3 weeks. No stomach upset. Haven't noticed any results yet but am optimistic.

I used this product in my bulk. I definitely feel an increase in strength and recovery. I also noticed I get better sleep if I take a pill before bed which is a great side effect! Highly recommend.

Your Questions, Answered.

Can I stack this with Thrust?

Since both products contains KSM-66 Ashwagandha, we do not recommend you stack them. If you are choosing between Hard Muscle Builder and Thrust, we recommend Thrust for overall sexual health, and Hard Muscle Builder if you’re solely focused on physique related goals.

The label says to split my dosage, but I keep forgetting to take the capsules. Is there any problem to taking them all at once?

Great question! In order to remember to take all the capsules, we recommend that you take the full serving of 3 capsules immediately after training. This will help reduce your cortisol levels after training and kickstart the recovery process.
