I have a question about GNC’s version of HOT-ROX Extreme. First of all i’ve been using HOT-ROX Extreme for a few months now and needed a new bottle. I didn’t have time to order it online somewhere else being Biotest is out of stock atm so I went to GNC.
Pills looked a little different with a orange stripe instead of yellow on them and noticed instead of just caffeine it contains Biotest GBX (Guarana-Berry extract) containing theophylline and caffeine.
I love the HOT-ROX i’ve been taking and hate to have something else i’m not used to in it. Does anyone know what difference if any this will have on the product. I heard Guarana is stronger then caffeine and not included in the usual bottles i’ve been buying…Will it work better, same, should I return it? I don’t want a crash afterwards or anything. Thanks
