Prices and full specs are in the comparison table and picks below.

My rule for this list: a flavored whey protein sold on Amazon whose listing names its sweetener and lists no sucralose, acesulfame potassium (ace-K), or aspartame, with free delivery without Prime on the day I checked, and at least 1,000 ratings. I ranked them by cost per 25 g of protein: price ÷ (servings × grams of protein per serving ÷ 25). If a listing contradicted itself about what’s in the tub, I left it out of the picks.

Why I made it: two of the three proteins I use most, regular ON Gold Standard and Ghost Whey, use artificial sweeteners, per the retailer ingredient lists I checked. Plenty of people just don’t like the aftertaste. When I searched for alternatives, the top results were a single-product page with no dated price, a stevia roundup (updated Oct 20, 2026) that gives price ranges with no check date and calls a cane-sugar powder its best value, and brand pages pushing plant protein or unflavored whey. None of them priced flavored, sucralose-free whey per gram of protein with delivery fees and rating counts. So I did.

How I built it: this guide is research-based. I compared current Amazon listings, their ingredient and nutrition info, and Amazon’s review summaries. I’ve used Transparent Labs myself; I haven’t used the other powders here. Prices are what Amazon showed on Nov 3, 2026, so check the price in your cart before you buy.

Read the label, not the front of the tub

“No artificial sweeteners” on the front doesn’t tell you what’s actually in it. Here’s what I check:

1. Find the ingredient list. Sucralose, acesulfame potassium (ace-K), and aspartame are the three I screened out.
2. See what replaced them. Stevia (sometimes listed as Reb-A or Reb-M), monk fruit, erythritol, allulose, or plain cane sugar. “No artificial sweeteners” can still mean real sugar.
3. Do the per-gram math. Scoop sizes run from 21 g to 28 g of protein, so price per scoop is misleading. Cost per 25 g of protein lets you compare tubs fairly.
4. Add delivery. One tub here looks cheap until you add an $11.13 delivery fee.

The picks

1. Transparent Labs Grass-Fed Whey Isolate: best for most people

This is the one I’d point most people to. I’ve used it and recommend it. The Milk Chocolate tub was $64.99 for 30 servings with free delivery, which is $2.17 a scoop or $1.93 per 25 g of protein. It has 28 g of protein per scoop, the most of anything here. The listing’s ingredients are short: whey protein isolate, cocoa, natural flavor, salt, and stevia. It’s rated 4.7 from 2,234 ratings, the highest rating here. Amazon’s review summary says most buyers like the taste, value is mixed, and some say it foams when blended, so a shaker may work better than a blender. Other flavors I saw include French Vanilla, Chocolate Peanut Butter, Strawberry Milkshake, and S’mores. Check price on Amazon

2. Levels Grass-Fed Whey (5 lb): lowest cost per 25 g

If you go through protein fast, this is the cheapest per gram of anything that met my rules. The 5 lb Pure Chocolate tub was $129.99 for 71 servings with free delivery, which is $1.83 a scoop or $1.91 per 25 g of protein. It has 24 g of protein per scoop. The listing says it’s grass-fed whey concentrate with cold-pressed cacao, monk fruit, and sunflower lecithin, and no “so-called natural flavors.” It’s rated 4.4 from 5,067 ratings. Amazon’s review summary says most buyers like the taste and how it mixes, but texture is mixed (some call it grainy), some say it isn’t very chocolatey, and stomach feedback is split. Want a smaller tub first? The 2 lb Pure Chocolate was $57.99 for 28 servings, $2.16 per 25 g. Check price on Amazon

3. Jocko Fuel Mölk Whey: lowest tub price

This was the cheapest tub that met my rules: $49.99 for 26 servings of Chocolate Milkshake with free delivery. That’s $1.92 a scoop, but only 22 g of protein per scoop, so it’s $2.18 per 25 g, the most per gram of my three picks. It’s not straight whey: the listing says it’s a blend of whey concentrate, whey isolate, micellar casein, and egg white, so skip it if you avoid egg. It’s sweetened with monk fruit and stevia (Reb-M). It’s rated 4.5 from 4,728 ratings. Amazon’s review summary says some buyers find it very sweet, and digestion feedback is mixed. Check price on Amazon

How to choose

1. Want the most protein per scoop and the highest rating? Transparent Labs.
2. Buying in bulk and watching cost per gram? Levels 5 lb.
3. Want the lowest price at checkout? Jocko Mölk, as long as egg and casein are fine for you.
4. Not sure about stevia or monk fruit? Taste is personal. Buy the smallest tub first.

FAQ

Is “naturally flavored” the same as sucralose-free? Not always. Check the ingredient list. Some naturally flavored powders use stevia, some use monk fruit, and some use cane sugar.

Is sucralose bad for you? I’m not a doctor, and this post isn’t about health. I made it for people who’d rather avoid the taste or just prefer these labels. If you have health questions about sweeteners, ask your doctor or a registered dietitian.

What about unflavored whey? Unflavored whey has no sweetener at all, and it’s usually cheaper per gram. It just doesn’t taste like much on its own. This list is for people who want a flavored shake.

Honorable mentions: good proteins that missed my rules

Orgain Grass-Fed Whey (Vanilla Bean). This was the cheapest per gram of protein I found: $31.52 for 20 servings of 21 g, which is $1.88 per 25 g, rated 4.5 from 1,902 ratings. Two things kept it out of the picks. Free delivery needs Prime or a $35+ order, and the Amazon ingredient list cuts off after “grass fed whey protein concentrate, organic erythritol, organic creamer base…”, so I couldn’t confirm the full sweetener list. The listing does say no artificial sweeteners and 1 g of sugar per serving. A serving is 2 scoops. If you have Prime, check the label photo and it could be a good budget pick. Check price on Amazon

Optimum Nutrition Gold Standard 100% Whey, Naturally Flavored (Chocolate). I’ve used Gold Standard and like it. This version swaps the artificial sweeteners for stevia and cane sugar, per the listing, and contains soy. The 1.9 lb tub was $50.18 for 27 servings of 24 g ($1.94 per 25 g), but delivery was $11.13, which pushes it to $2.37 per 25 g. It also had only 668 ratings. If it shows up with free delivery, or you add it to a bigger order, it’s worth a look. Check price on Amazon
