    how long does this product last?

    As with all weight gain or protein powders it entirely depends on your bodyweight, your goals, and your current dietary requirements from the supplement. For most people this tub will last effectively 4 - 6 week of consistent use.

    Hi, Why do I try to buy this product and it never loads, Would appreciate it if you aloud me to purchase this or I will have to shop somewhere else.

    Johnathan what is the exact issue?? Some times the store is so busy or yoru own browser could play up please advise?

    hi, i play rugby at for a premiership academy and as i have just been signed this year would like to bulk up, i have recently been taking lots of other supplements recommended by the club but i have been tipped off by a friend that serious mass is the best. my question is does it contain any substances banned by the rfu? as if it does i could be charged with a 3 year ban. thanks

    I am unaware of any bannes substances in any protein based supplement. All I can say to eb 100% sure please use a product called Lab Sries Gainer from CEL Nutrition or CEL Supplements which have a drug testing policy of 100% drug FREE. Serious mass is a US based product and some ingredients may be frowned upon here in the UK .

    Serious mass, is it any good?I have not tried it.

    If you havent tried serious mass and are a gainer fan, then serious mass will tick your mass gaining box. We sell a huge amount of serious mass and the customers who buy it are regular to the serious mass brand. Thanks
