Section 1
Protein: five extra grams come in a larger serving
More protein per labeled scoop: TL. Its serving is larger, so this is not an equal-weight comparison.
TL Whey Isolate
28 g
Milk Chocolate · 34.9 g scoop
Phormula-1
23 g
Chocolate Milkshake · 29 g scoop

This compares TL Milk Chocolate with Phormula-1 Chocolate Milkshake. The figures apply to those labels, not every flavor. There is no matched Phormula-1 taste or digestion test here.

Protein makes up about 80% and 79% of powder weight, respectively. That is label arithmetic—not a purity test or evidence that one builds more muscle.

Compare equal protein portions rather than assuming the larger scoop or lower-calorie scoop is better.

Section 2
Sweeteners and the Phormula-1 formula update
For avoiding artificial sweeteners: TL. Phormula-1 Chocolate Milkshake still lists sucralose.
TL Whey Isolate
None
Artificial sweeteners · reference label
Phormula-1
Sucralose
Chocolate Milkshake · sweetener listed

1st Phorm says the updated Phormula-1 removes artificial flavors and dyes, not artificial sweeteners. Those are different categories.

Choose TL when avoiding sucralose matters to you; check your chosen flavor’s label. This is an ingredient preference, not proof that one brand is healthier or tastes better.

Section 3
Level-1 is not Phormula-1

Level-1 Birthday Cake lists whey protein concentrate, 24 g protein and 120 calories per 32 g serving. It does not list casein. Level-1 is a separate product, not another Phormula-1 flavor.

Check the exact tub if you need casein. A serving of protein powder is not automatically a nutritionally complete meal.

Section 4
Testing claims should name the product and program

Phormula-1 Chocolate Milkshake has an NSF Certified for Sport listing covering specified lots. That does not certify every 1st Phorm product.

TL’s linked Oatmeal Chocolate Chip laboratory report applies to that identified flavor and batch—not the Milk Chocolate label compared here.

Match the product, flavor, lot and testing scope. Neither document establishes a muscle-growth advantage over the other protein.

Section 5
Pre-workouts: do not confuse Project-1 with Pro
For less caffeine: BULK. Project-1 Pro has the higher dose and adds yohimbine; more stimulants are not automatically better.
BULK
200 mg
Regular BULK · caffeine per serving
Project-1 Pro
350 mg
Pro · caffeine per serving; includes yohimbine

Regular BULK’s reference panel lists no creatine. Project-1 Pro lists 5 g creatine monohydrate and 2.5 mg yohimbine HCl, alongside its 350 mg caffeine.

Project-1 and Project-1 Pro are different products. Match the full name and panel before buying. Added yohimbine also needs separate consideration, especially with stimulant sensitivity or medication use.

Section 6
Pros and cons of the protein pair

Choose by your ingredient preferences and cost for equal protein amounts—not a blanket claim that one brand builds more muscle.

TL Whey Isolate

Pros
28 g protein per reference serving.
No artificial sweeteners on the reference label.
Cons
Larger scoop: compare equal protein portions.
No matched Phormula-1 taste test here.

Phormula-1

Pros
Comparable whey-isolate formula.
NSF listing for specified Chocolate Milkshake lots.
Cons
Reference flavor contains sucralose.
23 g protein per scoop; the serving is smaller.
Section 7
Value: compare equal protein amounts
More protein per reference tub: TL. That is 840 g versus 690 g; the better deal still depends on price.
TL Whey Isolate
840 g
Milk Chocolate · 30 × 28 g protein
Phormula-1
690 g
Chocolate Milkshake · 30 × 23 g protein

The reference tubs contain 30 servings each. Total protein is calculated from their named-flavor labels, not measured in a laboratory.

Cost per 25 g protein = tub price × 25 ÷ (servings × protein per serving).

TL could cost about 21.7% more per tub and still match Phormula-1’s cost per gram. Compare eligible prices in the same market, including shipping and subscription or first-order restrictions.

Section 8
How to choose and use the right product

Adjust your protein portion to your needs and check allergens. Phormula-1 Chocolate Milkshake contains milk and carries a shared-facility warning; “isolate” does not mean allergy-free.

For pre-workouts, follow the exact label and consider other stimulants, medications and health conditions. A formula with yohimbine is not equivalent to caffeine alone.

Section 9
Final verdict: choose a product, not a whole brand

Pick TL Whey to avoid artificial sweeteners; consider Phormula-1 when its ingredients and price suit you. Compare equal protein amounts before deciding value.

Choose your pre-workout separately. BULK and Project-1 Pro differ in caffeine, yohimbine and creatine—not just branding.
