TNT Mercury Black Mass — Designer Lean Mass Gainer 4kg

Black Mass — Lean Size, Built Properly

Not every gainer has to be a calorie bomb. Black Mass is TNT Mercury’s designer lean-mass meal replacement, made for lifters who want to add quality size while keeping fat gain in check. At its core is the Phase-4 protein matrix, which includes hydrolysed beef protein — a distinctive protein source geared towards quality lean gains rather than sheer bulk.

Where quick-burning gainers spike and crash, Black Mass adds sustained-release carbohydrates that support steady energy and muscle growth across the day. That combination — a multi-phase protein matrix plus slower carbs — is what separates a designer lean-mass formula from a standard weight gainer, and it is why Black Mass sits at the premium end of the TNT Mercury range.

Pick it up online or at any Nutrition Rage store across South Africa in rich Chocolate Nut flavour.

FAQs

Q: How does Black Mass differ from Atomic Mega Mass and Supa Mass?
A: Black Mass is the lean option. Atomic Mega Mass and Supa Mass are calorie-dense bulk formulas, while Black Mass uses a Phase-4 protein matrix with hydrolysed beef protein and sustained-release carbs for cleaner, steadier gains.

Q: Can I use it as a meal replacement?
A: Yes — it is formulated as a lean-mass MRP, so it works well between meals when a full plate of food is not practical.

Q: Will I gain fat using a mass gainer?
A: Body composition comes down to total intake and training. Black Mass is specifically designed for lean mass building, but track your overall calories to keep gains where you want them.
