Warrior Serious Protein - 500g

No. Serious Protein is a blend of soy protein isolate, skimmed milk powder, casein and glutamine peptides. It gives you the same 24g of protein per 30g scoop as a whey concentrate, at a fraction of the price whey costs this year.

Because it's a complete protein (all nine essential amino acids, PDCAAS score 1.0, the same top mark as whey and casein) at a price that lets us sell a 24g-protein shake for 78p. We add skimmed milk and casein for taste, texture and slower-digesting milk protein. Whey would have cost you three times as much this year.

No. The largest analysis on the subject pooled 41 clinical studies and measured testosterone in 1,753 men: no effect of soy protein or isoflavones on total testosterone, free testosterone or oestrogen, at any dose or duration (Reed et al., 2021). It confirmed a 2010 meta-analysis that found the same. If someone tells you otherwise, ask them for their study.

Protein contributes to the growth and maintenance of muscle mass, whatever the source, as long as it's complete and you get enough of it. In the trials that put soy against whey over 6-12 weeks of training, people gained the same muscle and strength on either (Messina et al., 2018, meta-analysis of 9 studies; Lynch et al., 2020, randomised trial).

The sports nutrition consensus is 1.4-2.0g per kilo of bodyweight a day if you train, spread across three or four feeds of 20-40g (ISSN position stand, 2017). For an 85kg man that's roughly 120-170g a day. One scoop is 24g of it.

Whenever you're short of protein. After training is the obvious one, but breakfast, the mid-afternoon gap and the drive home all count. The pack says any time, pre, intra or post, and it means it.

Soy protein isolate, skimmed milk powder, glutamine peptides (from hydrolysed wheat protein), casein, flavouring, cocoa (chocolate) or beetroot colour (strawberry), an anti-caking agent and sucralose. No thickeners, no maltodextrin, no added sugar (contains naturally occurring sugars). That's the whole list.

No, no, and not certified. It contains wheat (the glutamine peptides are made from wheat protein), so it isn't suitable for coeliacs. It contains milk, so it isn't vegan, though it is suitable for vegetarians. It doesn't carry a halal mark.

A little, from the skimmed milk powder. The 1.4-1.8g of sugars per serving is essentially all naturally occurring lactose. If you're lactose intolerant, this isn't the one for you.

Sucralose, a small amount. No sugar is added; the sugars on the label are the lactose from the milk powder.

No. It's a protein shake: 107-110 calories, 24g protein, 0.3g fat. Add oats, fruit or milk if you want a meal.

It's a food, not a medicine, but it's designed for adults. For anyone under 18, and for pregnant or nursing mothers, the label says check with a qualified health professional first, and we'd say the same.

Best before is printed on the lid: three years from production. Keep the lid on, in a cool, dry cupboard.

Milk. 250-300ml of cold milk is what turns this into an actual milkshake, not just a protein shake — it's how the flavours (Chocolate, Strawberry, Vanilla) taste like the real thing. Liquid in first, then the scoop, shake hard for 30 seconds, let it settle, shake again.

Three reasons. It isn't whey, and whey has more than doubled in price in a year. We make it ourselves in Manchester, so nobody else's margin is in the tub. And we don't pay influencers to tell you it's good.

In our own BRCGS-certified factory in Trafford Park, Manchester. We've made sports nutrition there since 2008.

Pick a flavour, choose how often (every 2 weeks suits most people at a scoop a day), and we'll send it. Change flavour, skip a delivery or cancel any time from your account.

Because we don't add any. The 1.4-1.8g of sugars per serving occur naturally in the skimmed milk powder (it's lactose). The law requires us to say 'contains naturally occurring sugars' next to the claim, which is what the asterisk on the tub is for.
