Product arrived within a few days. Excellent service.


I was sceptical to begin with by using this product as I have been disappointed by similar products from different companies. I also have a serious quad tendon rupture requiring surgery and have been unable to train legs for about 2 months. Within the first week I was feeling full and my appetite had definitely increased. I also put on 3 kgs. By the end of week two I had gained a total of 5 kgs with no noticeable fat increase AND also without being able to train legs. Needless to say I am really impressed by this and will definitely reorder.

Awesome product

I have purchased the mass stack 3 times now and my weight and strength have gone through the roof. AJ answered all my questions very quickly and delivery was within 2-3 days of ordering which I love. Highly recommend well done AJ and team BIGBoyz
