Curated, not stocked.
Mass gainers earn a place only when the formulation is honest about what is inside. Transparent Labs is a brand our team trusts precisely because it publishes a full label — no proprietary blends, no inflated claims. The combination of grass-fed whey and complex carbohydrates reflects how a clinician would approach a mass-gain protocol: adequate protein for muscle protein synthesis, and carbohydrates chosen for quality as much as quantity.
About this product
Mass Gainers - Sweet Vanilla
Transparent Labs Mass Gainer in Sweet Vanilla is a high-calorie protein and carbohydrate supplement designed to support muscle growth and weight gain for those who struggle to meet their energy needs through food alone. The formula centres on grass-fed whey protein — a fast-digesting, leucine-rich source well-suited to post-workout recovery — paired with complex carbohydrates that provide a sustained release of energy rather than a sharp glucose spike.
This product suits hard gainers, athletes in demanding training blocks, or anyone whose caloric expenditure consistently outpaces their appetite. It fits best around training — either post-workout to prime muscle protein synthesis, or as a between-meal addition when hitting daily calorie targets through whole food alone is impractical.
Transparent Labs has built a reputation in the performance supplement market for straightforward labelling and ingredient transparency, avoiding proprietary blends that obscure what you are actually consuming. The grass-fed whey source is a meaningful formulation choice: the protein class is well-studied for muscle repair and hypertrophy, and the use of complex rather than simple carbohydrates reflects a more considered approach than many mass gainers on the market, which lean heavily on cheap sugars to inflate their calorie count. For those with a confirmed training stimulus and a genuine caloric deficit relative to their goals, a well-formulated mass gainer can be a practical and reliable tool.

Common questions
Frequently asked
Who is this product actually suited to?
It is best suited to people with a genuine caloric deficit relative to their muscle-gain goals — hard gainers, athletes in heavy training blocks, or those with high daily energy expenditure who cannot meet their targets through food alone. It is not a substitute for a structured diet and resistance training programme.
Why grass-fed whey rather than standard whey?
Grass-fed whey is sourced from cows raised on pasture rather than grain-fed systems. As a protein class, whey is rich in leucine, the amino acid most closely linked to triggering muscle protein synthesis. The sourcing choice reflects a formulation standard rather than a functional difference in protein digestion.
How does this differ from a standard whey protein?
A mass gainer provides a significantly higher calorie count per serving by combining protein with a substantial carbohydrate load. A standard whey protein is primarily a protein supplement with minimal carbohydrates. If you are already meeting your calorie targets, a standalone protein powder is likely the more appropriate choice.
Is it suitable for people with lactose intolerance?
Whey protein is derived from milk, so it contains lactose. Sensitivity varies — many people with mild lactose intolerance tolerate whey concentrate or isolate reasonably well, but if you have a confirmed dairy allergy or significant intolerance, this product is unlikely to be suitable. Check the packaging for full allergen information.
How long before I notice a difference in body composition?
A mass gainer supports weight gain only when total daily calorie intake exceeds expenditure. Given a consistent training stimulus and sufficient caloric surplus, meaningful changes in muscle mass typically take several weeks to months. Supplements accelerate nothing on their own — the training and diet context is what drives the result.
