SIDE-BY-SIDE COMPARISON | NOVEMBER 2026
Aonic Fuel vs. Transparent Labs: One Has 23 Flavors and Two Testing Badges. The Other Costs Members $0.98 a Scoop
Aonic Fuel puts 32g of lactose-free milk protein and 5g of fiber in a 180-calorie scoop. Transparent Labs' grass-fed whey isolate gives 28g in 130 calories, with 23 flavors and Informed Choice testing. Aonic is my pick on price per gram of protein, if you join its paid club.
Wellness Journal is an affiliate publisher that promotes Aonic and may earn a commission on sales. Aonic's member price requires Aonic Club: $49 for the first 12 months for founding members, then $149 a year, renewing automatically. Member orders under $50 ship for $7.49. Aonic products are final sale.
Why I compared these two
Aonic Fuel caught my eye because of the label: 32g of protein and 5g of fiber in one scoop, with 0g added sugar and no artificial sweeteners. The protein is lactose-free milk protein, sweetened with stevia and monk fruit, in Rich Chocolate or Smooth Vanilla. A pouch holds 24 servings.
Transparent Labs is the obvious alternative. Its Grass-Fed Whey Protein Isolate has 28g of protein and 1g of sugar in a 130-calorie scoop, with testing badges on the tub. A 2LB tub of 30 servings is $64.99 one time or $58.49 on subscription. I wanted to know if Aonic's member price was worth giving those things up.
I worked from what each brand publishes: product pages, nutrition labels, ingredient lists, refund and shipping policies and each store's review feed, all read on November 11, 2026. I'm not a lab, so I've kept this to things you can check yourself.
At a glance: Aonic Fuel vs. Transparent Labs
What each brand publishes, in one table. My opinion comes after.
| Spec | Aonic Fuel | Transparent Labs |
|---|---|---|
| Protein per scoop | 32g in a 54g scoop | 28g in a 34.9g scoop |

Green marks the better pick where a number or a yes/no settles it. Protein and calories per scoop are left unmarked because the scoops are different sizes.
What's in each scoop
Two different proteins, both sweetened with stevia. The differences are in the fiber and the thickeners.
- Lactose-free milk protein isolate and lactose-free skim milk powder, with a complete amino acid profile
- 5g of soluble tapioca fiber in every scoop. Transparent Labs has none
- Stevia leaf extracts and monk fruit extract, real cocoa or vanilla extract, and 0g added sugar
- A gum blend of cellulose gum, xanthan gum and carrageenan. One one-star review on Aonic's store names the carrageenan and gums as the reason
- It contains milk. The label says lactose-free, but it isn't vegan or dairy-free
- Aonic says it's easier to digest than whey, marked with the FDA disclaimer asterisk. I found no study on this product
- Grass-fed whey protein isolate, and the label says 100% of the protein comes from grass-fed cows
- Six ingredients in Milk Chocolate: whey isolate, cocoa powder, natural flavors, salt, stevia extract and sunflower lecithin
- No gums on the list, and page badges for no artificial sweeteners, coloring or preservatives
- 0g of fiber on the label
- Its page says the isolate is filtered to remove "virtually all of the lactose," but its FAQ says people with severe lactose intolerance shouldn't drink whey
- Gluten-free, which Transparent Labs says it tests this product for
Two different proteins. Transparent Labs is a grass-fed whey isolate with a short label and no gums. Aonic Fuel is lactose-free milk protein with 5g of fiber, plus a gum blend that includes carrageenan. If lactose gives you trouble, Aonic is labeled lactose-free. Transparent Labs says its isolate has virtually all the lactose removed, but tells people with severe lactose intolerance to skip whey. Neither suits a milk allergy, and two low reviews on Aonic's store mention stomach upset. If you want the shortest ingredient list, Transparent Labs has it. Call this round even.
32 grams or 28 grams
Aonic's scoop is bigger, so look at the whole label before you count grams.
- 32g of protein in one 54g scoop, the most of the two per scoop
- 5g of fiber and 180 calories. Aonic says the fiber supports satiety, marked with the FDA disclaimer asterisk
- 7g of total sugars in the chocolate, 0g of it added. Transparent Labs has 1g
- 14g of carbs in a chocolate scoop and 13g in vanilla, against 1g for Transparent Labs
- It's thick. Several reviewers on Aonic's store say it needs extra water or a blender
- One scoop goes into 12 to 14 fl oz of cold water or milk
- 28g of protein in a 34.9g scoop of Milk Chocolate, at 130 calories
- 1g of carbs, 1g of sugar and 1g of fat a scoop
- More protein per calorie: about 21.5g per 100 calories, against about 17.8g for Aonic
- 0g of fiber on the label
- 210mg of sodium a scoop, against 270mg for Aonic's chocolate
- French Vanilla matches it at 130 calories and 28g of protein, with 0.5g of fat
Per scoop, Aonic has more protein and the only fiber. Per calorie, Transparent Labs is leaner: 28g for 130 calories against 32g for 180. If you track carbs closely, 1g against 14g matters, and Transparent Labs wins that. If you want one shake that keeps you going between meals, Aonic's fiber and thick texture are what several of its buyers say they like.
Testing and sourcing
Only one of these brands shows a third-party certification on its product page.
- The product page shows no third-party testing or certification badge
- It doesn't say where the milk comes from or where the powder is made
- It publishes what each 24-serving order costs it: $14.88 ingredients, $2.00 manufacturing, $1.00 packaging, $0.45 freight, $3.00 pick, pack and payment, and a $2.13 operations fee
- Its product page doesn't link a lab report or certificate of analysis
- Most orders arrive 2 to 5 business days after processing, per its shipping policy. US only
- Informed Choice and Informed Protein badges sit on the product page and on the tub
- The page has a Third-Party Testing section that links to lab certificates
- It says it tests this product for gluten
- The label says 100% of the protein is from grass-fed cows, and its product description says the cattle are American
- Its FAQ lists ISO-certified lab testing for heavy metals and microbes and Prop 65 testing, with NSF testing still rolling out
Transparent Labs wins this one clearly. Its whey carries Informed Choice and Informed Protein badges, with lab certificates linked from the product page. Aonic shows no certification. What Aonic does publish is its cost breakdown, down to $0.45 of freight per order, and that shows how the price is built. It says nothing about what's in the powder. If third-party testing is a must for you, buy Transparent Labs.
What you actually pay
Neither brand was running a sale. Aonic's page strikes through its $63.99 price next to the $23.46 member price, and that price needs a membership, so I priced it both ways.
- Member price is $23.46 for 24 servings, about $0.98 a scoop, as a one-time order or a monthly delivery you can skip or cancel
- Aonic Club is $49 for your first 12 months while the 10,000 founding spots last ($99 once they're gone), and it renews at $149 a year
- The first order, membership plus a pouch, is $72.46 with free shipping, and members get a free Aonic Hydration 30-pack
- Orders under $50 pay $7.49 shipping, so a single pouch is $30.95. Three pouches in one order ($70.38) ship free
- Members can buy up to three of each product in any 30 days
- Without the membership, a pouch is $63.99, about $2.67 a scoop
- A 2LB tub is $64.99 one time for 30 servings, about $2.17 a scoop
- Subscribe & Save takes 10% off, $58.49 a tub, delivered every 15, 30, 45 or 60 days
- The 4LB tub is $109.99, or $98.99 on subscription, for 55 servings
- Subscriptions ship free, and one-time orders ship free over $99
- A single $64.99 tub is under that $99 line, and its policy pages don't list the charge, so check at checkout
- No membership needed for any of these prices
As a member, Aonic is the cheaper protein by a wide margin. Matched to the same 768g of protein, one Aonic pouch, Transparent Labs costs $53.48 on subscription or $59.42 one time, against $23.46 for Aonic. Add Aonic's $7.49 shipping and the membership, and Aonic still comes out ahead if you go through about a pouch a month. Skip the membership and Aonic costs more than Transparent Labs. The price only works if you join.
What buyers say
Both stores show a star rating and a review feed, so I compared them.
- 4.4 out of 5 from 155 reviews on Aonic's store
- 115 of the 155 are five stars, and taste and the thick, shake-like texture come up again and again
- Several reviewers say it keeps them full, and some use it in oats, coffee or baking
- 14 are one star, and eight of those mention texture: too thick, hard to mix or foamy
- A few don't like the taste of the stevia and monk fruit
- Two of the one-star reviews say the order hadn't arrived or never came
- 4.72 out of 5 from 8,325 reviews on its store
- That count includes some reviews of related products the store groups with this one, and the page says so
- About 85% of those reviews are five stars
- One recent one-star review calls it too sweet, and another says it tastes buttery
- Several recent one-star reviews say the order hadn't arrived or never came
- 23 flavors listed, from Milk Chocolate to Cinnamon French Toast. Six were out of stock in the 2LB size when I checked
Transparent Labs has the longer record: thousands of reviews across a long list of flavors, at 4.72. Aonic Fuel's 4.4 comes from 155 reviews, mostly five stars, and its one-star reviews are blunt about the texture. It's thick. If you like a shake that drinks like a milkshake, that's the appeal. If you want something thin in a shaker bottle, read those reviews first.
Guarantees and returns
These two policies could hardly be further apart, so read this before you order.
- Products are final sale: no returns, no exchanges and no money-back guarantee, for members or anyone else
- If a pouch arrives damaged or wrong, email within 90 days of delivery for a refund or a replacement
- Your first Aonic Club payment has a 180-day money-back guarantee. The product in that order isn't refunded, and you keep it
- Cancel the membership or a subscription any time in your account or by email, with no cancellation fee
- A 45-day satisfaction guarantee: a full refund or store credit within 45 days of delivery
- It may ask for photos or for the unused portion back, and if it does, you pay the postage
- It covers US buyers who bought from its site or an authorized seller
- Its policy says it can change or end the guarantee at any time without notice
Transparent Labs wins on returns. You get 45 days to decide, though you may have to pay to mail it back. Aonic sells its powder as final sale, so the only safety net is the 180-day refund on your first membership payment, and that doesn't cover the pouch. If you're unsure about a thick texture, that's a real risk with Aonic. Try one pouch before you stock up.
A year of protein, side by side
Two months in, the two cost about the same. After that, Aonic's member price pulls ahead every month.
My chart matches the protein: each month is 768g, one Aonic pouch, or about 27 scoops of Transparent Labs. Aonic's line includes the $49 founding membership and $7.49 shipping on every one-pouch refill after the first. Order three pouches at a time and they ship free, which brings Aonic's year to about $331. Transparent Labs' line uses the 2LB tub on Subscribe & Save, which ships free, and counts only the protein you drink. Its 4LB subscription brings that year down to about $592. In year two, Aonic Club renews at $149, so Aonic runs about $520 a year in single pouches or about $431 in threes, still under Transparent Labs. If the founding spots are gone, the $99 first year puts Aonic at about $463. The gap closes if you drink less. Below about five to eight pouches a year, depending on how you order and which tub you compare, the $149 renewal makes Transparent Labs the cheaper buy.

At member price, before shipping and the membership, Aonic Fuel costs less than half as much for the same protein, and it adds 5g of fiber. Transparent Labs gives you testing badges, 23 flavors, a leaner label and a 45-day guarantee, with no membership to manage. For me, the savings and the fiber win. If testing or easy returns come first for you, Transparent Labs is the safer buy.
I am not a big chocolate protein powder fan because it can taste chalky or not very good. This one is rich and creamy and not the least bit chalky.
Every feature, side by side
Ten things I checked on both. Each brand has rows the other can't match, so the last line says who each one suits.

What Aonic Fuel customers say
These are verified buyers on Aonic's store, quoted as written apart from two typo fixes, and I can't independently confirm them. The same feed has 14 one-star reviews, most about the thick texture, so read it yourself before you buy.
"Really enjoying this protein powder. The vanilla flavor is smooth and not overly sweet, and it mixes easily without a chalky texture. Great for a quick protein shake after a workout." Verified buyer
"I love this product. I use it for more than just a protein shake. Great for overnight oats and for homemade yogurt bars. Great taste and filling." Verified buyer
"Absolutely love it. You can feel how clean it is. Mixes well, dissolves completely in shaker. This has to be the first protein powder to keep me full for a while after taking it." Verified buyer
For the most protein per dollar, Aonic Fuel is my pick
I wanted 30g or more of protein in a single scoop at a price I'd keep paying. For members, Aonic is the only one of the two that does both.
Transparent Labs has real strengths: Informed Choice and Informed Protein badges, 23 flavors, 1g of sugar, a short ingredient list with no gums, a 45-day guarantee and no membership. If testing or easy returns matter most to you, it's the one to buy.
Price decided it for me. Matched to the same 768g of protein, Transparent Labs costs $53.48 on subscription, and Aonic charges members $23.46, or $30.95 with shipping on a single pouch. Even with the $49 founding membership, a first year comes to about $413 against about $642.
The label backed it up: 5g of fiber and a lactose-free label. Transparent Labs has no fiber and says its isolate is virtually lactose-free.
The trade-offs are real. Aonic is final sale, it's thick enough that some buyers reach for a blender, and the price depends on a membership that renews at $149 a year. Try one pouch, see how you get on with the texture, and decide on the rest from there.
Lactose-free milk protein with 32g of protein, 5g of fiber and 0g added sugar per scoop. Transparent Labs is leaner, has testing badges and is easier to return. If you want the lowest price per gram of protein, Aonic is the one.
