Full Review

Transparent Labs LEAN takes the trusted Transparent Labs formula philosophy and tailors it for those in a cutting phase or focused on body recomposition.

Energy & Focus: The same clean 200mg caffeine approach as BULK, delivering reliable energy without overstimulation. During a caloric deficit when you're already feeling depleted, the moderate approach is actually ideal — you don't want to add stim-crash to your already reduced calories.

Performance: Beta-alanine at 4g and betaine at 2.5g are at full clinical doses, ensuring your training intensity doesn't drop during a cut. Citrulline malate at 6g provides solid pumps, though not as dramatic as BULK's 8g dose.

Fat-Loss Support: Here's where LEAN differentiates itself: acetyl-L-carnitine (750mg), green tea extract (100mg), and chromium picolinate (200mcg) are included to support fat metabolism. Let's be honest — these aren't magic fat burners. But combined with proper diet and training, they provide a modest metabolic edge.

Transparency: Like all Transparent Labs products, every ingredient and dose is clearly listed. No hidden formulas, no proprietary blends.

Value: Same $49.99 price as BULK, which raises the question: if you're not specifically cutting, BULK offers more pump-focused ingredients for the same money. LEAN makes most sense during defined cutting phases.

The Bottom Line: LEAN is the right choice during a dedicated cutting phase when you want to support fat metabolism while maintaining training performance. During bulking or maintenance, stick with BULK for better pump ingredients.
