I've ordered loads, directly from amazon.co.uk and never had an issue. whichever way you cut it, £15 per kg is far too expensive for protein powde, but if you like it, go for it

vale.of.clwyd

Few reports of fake optimum nutrition supplied b Amazon, see reviews & optimum site to verify its a genuine product.

kos1c

I usually buy of their eBay page as I only need a single tub here or there, compared to being forced to spend over £30 for free postage. Their Rego Strawberry after workout is really nice, the chocolate not so much. Also their protein peanut butter bars are a nice treat, 20 for £20 (free post). https://www.ebay.co.uk/str/scienceinsport

Nad_84

My protein is usually about 8-10 per kilo Otherwise likely to be a optimum nutrition for black Friday on Amazon, there was last year and the year before 2.27kg for £35

Not really a deal at £10.00 this is just an offer which they keep repeating to get rid of this years stock. We need some more freebies really

justhelping

Voted Hot as this is a good deal against normal price and places like Wiggle. However, If you have a Costco Card, packs of 14 of these mixed Gels for about £7, always work out cheaper than SiS and Decathlon. Unless you are ordering other things from SiS, or want different flavours than the standard ones.

The.Crew.Designs

They are nearly £10 each with delivery (shock)

Seems to be a glitch with the 2for deal and the 10% deal. I'm getting the 2for£25 Regis coming up at £15.40 Not sure how good value it is though

bod1611

The price only comes down once you're on the payment screen. I've just done it and it came down to £74ish (which it did last time) but when i placed the order, it reduced again down to £51. Can't promise the last step will work again but i suppose £74 for 6 1.6kg tubs is still a bargain at just over £12 each.

You should post that voucher code as your own deal. The free bottle offer is gone now so this deal is expired.

i am not sure whether you get the additional free gift with this code but you do certainly get the free bottle offer 25% off SISCP25

The only other code that works for me at the moment is FUEL-ME but you can only use 1 code at a time and the Football one has better value gifts right now. There may be other codes in future or the free bottle offer could disappear at any time at which point this deal will expire.

Lol on this site is tricky to distinguish the genuine questions... The ones I've tried from SIS contain maltodextrin. Allegedly better than glucose but tbh little different in terms of metabolism

sonofgojira

Lol, I know that, just wondering if it's bad sugar eg glucose or something. Want it for the gym but not if it's detrimental

Swidc

Of corse, your body needs sugars, but it's not the same sugar you can get at Tesco...

Yeah they are good to keep on you for emergencies but the only downside is I cannot seem to avoid getting the gel on my handlebars and brake levers.... Sticky :(

I think the new sign up deals are gone, before hand you used to get 500 points. There is something on their site about getting 500 points for being refered by another person but I have not tried it so I cant confirm if it works (500 points would be £5 off, so you could get Premier for £4.99 instead of £9.99) I paid for delivery for each order individually a few times but its £3.99 a pop so I just got Premier and get them all included as part of that now for a year

Shinoke

Not used them yet, but seen lots of deals and mention of premier etc. What's the best process to go through as a new customer to get the best deal? I've just signed up to their newsletter but haven't received anything from that. Do you sign up to premier when you buy something?

Not sure if something has changed in how they apply these codes, but with an existing account and Premier paid for already in a previous order, there seemed to be no way to get the 6 gels completely free - was only allowed to add the freebie with another purchased item.

'OP: Where is the evidence for the £5 credit with new account sign-ups getting premiere for £4.99?? It says it on this page https://www.scienceinsport.com/help/sis-loyalty

victor99

Register and you get 250 points which is £2.50, go into settings and sign up to the news letter for another 250 points, thats £5. Premier is 9.99, so you are going to get it for £4.99.

muppetrider

With help from victor on UKHD (info *all* staff failed to provide when asked!) The extra 250 comes from signing up for the newsletter. EDIT: So after effectively wasting all this time, getting the newsletter and communicating with the clueless staff.. *and* paying £5 for 'free' delivery of my 'free' item the code is not working and they want £19.40 for the gels meaning a total of £24.40 spent if I follow this. Message is: "COUPON CODE IS NOT VALID" So will 'attempt' to go through the long queues and to try and my money back.

paul_boden

When I’ve done it recently there was 500 points waiting for me at checkout which definitely equates to £5 off premium and an extra freebie item.

muppetrider

Could I please ask for clarification of the above claims. Customer service are saying they don't know anything about free £5 credit with Premier and a new account - Last one (Maria) I specifically asked about free £5 credit with new account and premiere answered that with a new account £9.99 get's you a year delivery and that's it. Is there a link to the info about the apparent free £5 credit because I can't find anything and chat staff are none the wiser. Edit: I spoke to another member of SIS chat staff (Benadetta) and was told the same (no extras besides delivery regardless of new account) then I questioned her again and she changed her story and said you get 250 points for a new account.. which say says would be worth approx £2.50 credit although I don't know what the requirements are re: minimum points cash out or conditions etc. 'OP: Where is the evidence for the £5 credit with new account sign-ups getting premiere for £4.99?? Apologies if I've missed something but if these chat staff are correct then a lot of UKHD readers will be disappointed paying £10 expecting to get premiere for effective £5 due to this imaginary(?) credit you claim. This is a big money spinner for SIS.. are you affiliated with them or taking handouts? - Details seem shady, I nearly dropped £10 expecting my £5 credit but staff say that's nonsense. Apologies again if I've missed something.. very possible! Cheers All :D
