The emergence of TikTok Shop as the next frontier in e-commerce wasn’t on many people’s bingo cards.
What started as a platform for sharing memes, dance challenges, and humorous skits has evolved into one of the most powerful tools for selling online.
According to Statista, TikTok Shop’s Gross Merchandise Value (GMV) has boomed from circa $1 billion in 2021 to an eye-watering $33 billion in 2024.
That sharp rise hasn’t escaped the notice of the biggest brands in health and fitness. When leveraged correctly, TikTok Shop can be a goldmine for businesses looking to expand their reach and drive sales.
Global sports nutrition heavyweight Grenade was keen to do just that.
The protein bar specialist approached Gymfluencers – the UK’s leading TikTok Shop agency, operating under the wider Fluencers Group umbrella – to bolster its presence on the app.
Backed by a specialist team of TikTok experts, Gymfluencers was ideally placed to optimise everything from Grenade’s back-end setup, affiliate scheme and product offering to its organic reach, ad spend and live schedule.
In this Grenade TikTok Shop case study, we’ll break down how Gymfluencers grew Grenade’s revenue on the platform by 414% in the first six months, taking an already global brand to new heights.
Grenade exploded onto the sports nutrition scene in 2010. Founded by Alan and Juliet Barratt, its mission was simple yet ambitious: create an iconic weight-loss supplement and become the go-to face of clean fuel.
Its first product, a fat burner fittingly dubbed the Thermo Detonator, was so effective that a friend described it as “like a Grenade”.
The name stuck, and that Thermo Detonator proved to be the big bang for the brand’s rapid expansion.
Today, Grenade is available in over 80 countries worldwide, proudly proclaiming a multi-award-winning product range.
The jewel of that offering is undoubtedly its Carb Killa protein bars – an iconic snack available in several beloved flavours, including the hugely popular OREO collaboration.
Stocked in supermarkets and convenience stores worldwide, Grenade’s protein bar is the benchmark of functional snacking and very much a category leader.
Buoyed by the success of its not-so-naughty treats, the brand’s impressive roster now features protein powders, apparel, protein spreads, pre-workout, and more.
When tasked with solidifying Grenade as a leading brand on TikTok Shop, Gymfluencers took a full-spectrum approach to make the sports nutrition giant truly unmissable.
Here’s what we delivered.
Hayley Collins, TikTok Account and Operations Manager, and her team of presenters immediately filled Grenade’s schedule with eight lives a month.
Fusing in-app sales tools such as discounts, giveaways and flash sales with education, community building and Hayley’s trademark high-energy charm, it wasn’t long before the needle began to jump.
In just 30 days, Grenade’s TikTok Shop revenue climbed 1,109% versus the previous month, with lives accounting for a staggering 60% of that growth.
With consistency and quality in equal measure, Hayley and co. kept the momentum rolling, returning a GMV increase of 699% from lives in the first six months.
From January to March 2026 alone, the streams have driven sales of 1,200 items from Grenade’s TikTok Shop, maintaining an impressive Click-Through Rate of 2%.
Complimenting a busy calendar of lives, Gymfluencers’ in-house content team filled Grenade’s profile with 60 videos a month, blending shoppable and organic content to hit the sweet spot between brand affinity and sales.
Thanks to Georgia Thomas, our very own hybrid powerhouse, Grenade was able to meet booming fitness trends like HYROX on gym floors and race circuits, without having to manage logistics.
Paired with a thriving affiliate community and strategic ad spend, which we’ll come to shortly, results were almost inevitable.
Daily posting fuelled a 267% spike in Product Card GMV within the first six months, accounting for almost 50% of Grenade’s TikTok revenue.
But none of that success was accidental. Behind the camera, Alison Morley, Gymfluencers’ Chief Operating Officer, ensured everything from SEO to shop and product setup was optimised for fruitful outcomes.
Affiliates rank among the most powerful routes to revenue on TikTok Shop.
Knowing full well the force of a thriving affiliate network, Gymfluencers doubled down in this area, scaling the community to over 8,600 creators.
However, when managing an industry juggernaut such as Grenade, quantity mustn’t come at the expense of quality.
The team cherry-picked only the very best profiles, ensuring every single one brought something unique to the table (and the For You Page).
With a small army of affiliates launching Grenade into every corner of the platform, sales soon started to compound.
In just six months, affiliate content drove over £380,000 in sales, marking a 690% increase in GMV.
That mammoth figure was bolstered by the careful use of ad spend, with 80% directed towards affiliate videos.
In the first three months of 2026, ROI consistently remained above 4, showing strong value for every penny deployed.
Late last year, Grenade once again showed why it sits on the throne of functional snacking by releasing a category-first Creme Egg collaboration.
The launch also represented the birth of a new Soft Core protein bar format, described as its “most indulgent offering yet.”
Unsurprisingly, the announcement generated plenty of buzz, and Gymfluencers made certain that every shriek of excitement reverberated around TikTok.
Why was this launch so huge? Before the drop date in December 2025, the team selected the highest-performing affiliates and briefed them on exactly what to say and when to post.
Affiliates and Grenade’s own native content formed a dual-pronged approach, meaning the Creme Egg bars were impossible to scroll past from the word go.
With content already locked and loaded, ad campaigns were able to be activated immediately.
And to solidify the debut as one of the biggest in Grenade’s history, Hayley ran dedicated Creme Egg lives, leveraging exclusive discount codes and giveaways for maximum impact.
This joined-up approach quickly translated to staggering sales data. In the first three months of 2026, consumers snapped up 18,439 Creme Egg bars from TikTok Shop, split across 16,541 orders.
But Grenade’s wider range wasn’t placed on the back burner while all this was happening.
Other key milestones included Grenade’s OREO four-pack reaching the UK’s top three viral products on TikTok Shop – a quite remarkable accomplishment.
With the team’s 360° support, it took just weeks for Grenade to leap from the chasing pack to a clear frontrunner on TikTok Shop.
In just six months, Gymfluencers helped pull the pin on 28,901 orders, translating to 43,613 items sold and a GMV increase of 414%.
As we head into summer, a crucial time for brands operating in sports nutrition, plans are already in place to hit more record-setting months and place Grenade’s bars, supplements and spreads in more gym bags than ever before.
