The cost and taste of this stuff is great. I got the vanilla because I'm not a massive fan of chocolate and with some milk and honey, it's very much drinkable.
Postage was also quite quick

Gross flavour taste like off milk. Next time I would rather make my own bulking shake. Was convenient to take to work. Doesn’t mix very well either. Would not buy again but I would recommend for the lazy beginner

Great taste and easy to consume. Makes workouts and muscle growth simple, especially with a busy lifestyle like mine, which can make it hard to consume enough calories without supplements.

Is Serious Mass ASADA approved?
No Serious Mass is NOT ASADA approved.
Hi, I messaged recently checking if serious mass was okay for me to take but I haven’t received a reply yet. I read somewhere that someone’s anxiety increased being on a certain type of protein, sorry I can’t remember what it was. So I was just wanting to check if this was okay to take with Efexor?Thanks heaps!
With pre-existing medical conditions and medications we ask you refer this question to your health care professional.
I was just wondering how many times a day I should take this and how much?
How much you take is dependant on your body type and diet. Have at least one full serve per day if you find that you struggle to put on weight. Otherwise you can have half a serve per day.
I just want to know if serious mass contain all the amino acids like it counterparts 100% whey protein which have all the EAAs, NON-EAAs and BCAAs in it?
Optimum Serious Mass shall NOT contain the concentration of Aminos that Optimum 100% Whey Gold Standard shall contain.
