If you would like to try them no worries you can do it.Bear in mind they are not fake but they are not what they advertise themselves by maligning other competitors. I sent few reviews for their products and apparently they never published mine on their website. Therefore I'll recommend please ignore the reviews in their website as they are selected by them(May be few fake ones too). I tried their 'NMN' supplement which is very expensive for the amount they supply. The companies like 'Youth and Earth' have certifications for their NMN product. The people at BS are doing day light robbery selling 724 mg of NMN at 57 GBP for 30 caps only. With the same money you can buy more than that amount from other trusted sellers like Youth and Earth or another Time Health(They are listed in Utherver website). These guys also charge ridiculous 4 pound for delivering a simple capsule. Please do your due diligence before buying from these guys.
Quantity: 724mg x 30 = 21720 mg = 21.72g
Cost: 57 GBP
Cost per gram = 2.62 GBP
Cost of 250 mg Capsule = 0.66 Pence
Youth and Earth:
Quantity: 250 X 60 = 15000 mg = 15g
Cost: 32-39 GBP(Use discounts in their website)
Cost per gram = 2.13 GBP
Cost of 250 mg Capsule = 0.53 Pence
So in the same 57 pound you can have 107 capsule(250 mg) almost 4 months supply from Youth and Earth.
A word of advice as you only need 250mg of NMN if you are 30-52 age and 52+ you need 500mg.More nmn is excreted from your body wasting your money. If you want higher dose you can just take more capsules(2x250 = 500mg). BS is ripping off customers even though they get their supplies possibly from Uthever or other Chinese companies. It's time to expose this company.
