What this review covers
- The no-blend label policy and what it means in practice
- Bulk pre-workout versus Lean pre-workout
- Creatine HMB and how it differs from plain creatine
- Hydration and amino products in the range
- Online-only buying and the price position
Verdict
Transparent Labs is the pick for a label-reader: a buyer who wants to know exactly how much of each ingredient is in a scoop, and who distrusts proprietary blends, will find this range reassuring. Bulk is the standard pre-workout, Lean is the lower-calorie, stimulant-aware sibling, and Creatine HMB is a distinctive creatine-plus-HMB formula. The trade is price and availability — it costs more than budget tubs, sells mainly online, and flavour choice is narrower than mass-market rivals. It suits an experienced trainer who reads panels; it is overkill for a first pre-workout buyer who just wants something simple.
Pros
- Every ingredient amount is printed on the label
- Bulk and Lean give a clear stimulant and calorie choice
- Creatine HMB is a distinctive formula, not a copy
- Third-party testing is part of the brand's pitch
Cons
- Higher price per serving than budget brands
- Mainly online, so no shop tasting or advice
- Narrower flavour range than mass-market rivals
Labels with nothing hidden
Transparent Labs' defining policy is label transparency: its products list the amount of every ingredient, and the brand states that it does not use proprietary blends, artificial sweeteners, colours or preservatives in its core lines. The pre-workout pair is Bulk, the standard-strength pre-workout for muscle-focused training, and Lean, aimed at buyers watching calories, with a different ingredient emphasis and stimulant profile. Creatine HMB combines creatine monohydrate with HMB, a compound the brand positions around muscle support, and it is sold as a powder distinct from plain creatine.
Around those sit hydration products, amino acids, and a small number of supporting powders, all sold mainly through the brand's own website and selected online retailers. Transparent Labs is an American company that grew through online fitness communities, and its reputation rests less on gym-shop shelf presence and more on the trust of buyers who compare labels line by line. That audience explains both the range's shape and its price.
Powders, sweeteners and the online shop
The range is powder-led, with tubs for pre-workout and creatine and stick packs or tubs for hydration, sweetened with stevia in the core lines rather than sucralose or sugar. That choice matters for taste: stevia-sweetened powders taste different from mass-market pre-workouts, and buyers who dislike stevia will notice it in every flavour. Flavour choice is deliberately narrower — a handful of fruit flavours per product rather than a long list — and new flavours arrive slowly. Because buying is online, the brand sells bundles and subscriptions, which cut the per-tub price but commit the buyer to a flavour before tasting, unless a smaller pack or sample is available.
Who it is for
Transparent Labs suits a trainer who reads supplement labels, dislikes proprietary blends, and is willing to pay more for disclosed amounts and stevia sweetening. It suits a buyer choosing between Bulk and Lean on a clear basis — training focus versus calorie awareness — and it suits someone who wants creatine with HMB rather than plain creatine. Online buyers comfortable ordering without shop advice will be at home here.
Who should skip it
Skip Transparent Labs if budget is the main driver, since plain creatine and budget pre-workouts are cheaper per serving, and skip it if stevia taste is a known dislike. Skip the stronger pre-workout servings if caffeine sensitivity is an issue, and skip a subscription until a flavour has been tried, since the online model makes returns awkward. Anyone with a health condition, pregnant, or on medication should ask a qualified professional before using pre-workout or creatine products. This is general information, not medical advice.

How to choose before you buy
Use the label as the comparison tool, since that is what the brand is selling. Compare Bulk against Lean on stimulant level and calorie-related ingredients first, and only then on flavour, because the two products answer different training goals. For creatine, decide whether HMB is wanted at all — if not, plain creatine monohydrate is cheaper and simpler.
On price, compare the subscription or bundle price per serving against a mass-market tub on the same basis, and weigh the transparency premium honestly: it is worth paying for if disclosed amounts matter to the buyer, and it is not if they do not. Buy the smallest pack of a new flavour first, even online, to avoid being locked into a large tub.
