E-commerce · Supplements & Nutrition
Buyers do not trust the tub until they have seen the lab report and the seal.
Protein powder is one of the most doubted products online. Buyers have read about fake tubs, short-filled scoops and listings that change after the reviews come in, so they look for proof before they look at the flavour. The seller's name, a batch number they can check and a seal they can see are what decide the order.
A 90-minute audit call and a written, scored report. Turnaround, reporting and term are agreed in writing after the audit.
In one paragraph
Protein supplement e-commerce is the online sale of whey, plant protein, casein and mass-gainer powders, usually in large tubs that buyers compare by cost per serving and by the seller's reputation. GullySales works on how your pages show the protein per scoop, the source and the proof of an original pack, and on bringing a buyer back when the tub runs low.
The buyer is also more informed than the page expects. They know the difference between a concentrate and an isolate, they have seen a lab report posted by a competitor, and they compare you on cost per serving with a calculator open.
Last updated 7 Oct 2026. Product, labelling and advertising rules for supplements & nutrition differ by product and change. We describe them in general terms, so check the current position with your own adviser or the regulator before you publish a claim.
Who it is for
This is written for you if you sell protein supplements online.
- Whey and plant protein brands selling in 1 kg to 5 kg tubs
- Authorised resellers of imported protein brands
- Sellers of mass gainers and weight-gain powders
- Vegetarian and vegan protein makers with a smaller, newer audience
- Brands selling in sachets and trial packs to first-time buyers
Not for
It is not the right fit if.
- A brand that wants the page to promise muscle, weight or fitness results
- A reseller of grey-market stock with no papers to show where it came from
How buyers choose
What decides the sale of protein supplements.
Protein per scoop and the scoop size
Buyers read grams of protein per serving and grams per scoop, then check whether the two match the marketing. A scoop that is small on the label but large in the video gets noticed.
Concentrate, isolate, blend or plant
Gym buyers search by type, and they judge a brand by which one it is willing to say plainly on the front of the tub.
Lab reports and batch numbers
Many buyers expect an independent lab test for the batch and a way to match the batch number on the tub to it. Where you have none, say so and show what you do have.
Flavour, mixability and the reviews that say so
A powder that clumps or tastes chalky is reported in reviews within days. Buyers read those lines before the star score.
Where sales are lost
What usually goes wrong when you sell protein supplements online.
In the words sellers use on the first call.
“Buyers keep asking whether the tub is original”
Every listing in the category faces it. The page needs the authorised seller details, a sealed-pack photograph and a batch check, placed before the question comes up.
“A competitor's tub is cheaper per kilo”
Price per kilo is the wrong comparison. The buyer who does the sum finds cost per gram of protein, and a page that does it for them in your favour or honestly shows the difference keeps them.
“Reviews complain about clumping or taste”
Reviews of a flavour spread to every flavour in the range. Mixing guidance, a trial sachet and a reply that names the flavour help more than one star's worth of apology.
“Our big tubs sell once a year”
A 2 kg tub runs out and the buyer does not remember you. Nothing connects the purchase to the next one.
The scope
The work we would propose for protein supplements.
Measured on purchases, conversion rate, cost to win a customer, average order value and repeat purchases. Anything here that needs a platform or tool we have not used with you is confirmed in the audit before it goes in the scope.
- Proof pages for original stockA section on each listing showing the sealed pack, the batch number, the authorised seller details and the lab report where one exists, shown above the add-to-cart button.
- Searches by type and by goal wording the label allowsPages for whey isolate, plant protein for vegetarians, protein without added sugar and similar searches, written from the label with no promised outcome.
- Cost per serving comparisonA comparison table between your tub sizes and flavours on your own store, and the listing titles and bullets on marketplaces set up so the serving count appears at first glance.
- Gym and creator contentTrainers and reviewers who mix and taste the product on camera. Briefs keep them to describing the product, and the brief is sent to your adviser before it is used.
- The reorder before the tub is emptyA message sent when the serving count says the tub is close to done, with the flavour the buyer chose and a larger size to compare.
What we do
What you get for protein supplements.
Each deliverable and what it is there to change.
A proof block for every protein listing
A reusable section with the sealed-pack photograph, batch details, seller authorisation and test report, so the buyer's authenticity question is answered on the page.
A cost-per-serving and protein-per-scoop table
Your range side by side on the numbers buyers calculate themselves, kept correct as pack sizes change.
A mixing and taste guide
Short instructions for shaker, blender and milk, with notes for the flavours that get complaints.
A first-purchase sample plan
Sachet and small-tub offers designed to turn a doubtful buyer into a buyer of the 2 kg size.

How it works
From your first message to the first report.
No open-ended retainer. Every step gives you something in writing.
First
Free audit call
90 minutes with whoever handles your enquiries: how they arrive, how fast they are answered, where they are lost.
After the call
Written, scored report
Six areas scored, fixes ranked by return and cost. If you want our help, the scope, the fee and the reporting come with it, in writing.
Before work starts
Baseline recorded
Enquiries by source, reply time, conversion and cost per order, written down so every later report has an honest comparison.
After the baseline
The first fix goes live
Usually the cheapest one on the report: reply time, a follow-up sequence or the marketing-to-sales handover.
As agreed
Report against the baseline
What moved, what did not, and what changes next, in plain words. How often you get it is set in writing before work starts.
At renewal
Renew on the numbers
The term ends and you decide whether to continue from the results. The length is agreed in writing before anything starts.
What we need from you
What to have ready before the audit call.
None of it has to be tidy. We read what you have.
- Lab reports and certificates you hold for each batch
- Your seller authorisation if you resell a brand
- Reviews that mention taste, clumping, scoop size or the seal
- Sales split by tub size and flavour
- Your current marketplace titles and bullets
Selling in India and abroad
Selling protein supplements beyond your own market.
Where you sell decides sizes, units, seasons and returns. We work from Bengaluru and have no overseas office, so for a new country we start from your own sales and the platforms you already use.
Protein powders are checked at borders
Customs and food regulators in other countries can refuse or hold powders with certain ingredients, sweeteners or claims. This is checked with your adviser and the destination's regulator before any shipment.
Large tubs are heavy parcels
Shipping a 2 kg tub abroad can cost more than the product. Smaller packs and sachets, or selling to Indian buyers abroad through a local stockist, are the first things we would look at.
