90 Caps

XL Nutrition BUILD, KSM-66 Ashwagandha, Fadogia Agrestis & Shilajit Stack

XL Nutrition BUILD is a 90-capsule natural testosterone support stack combining three of the most-researched adaptogenic and herbal ingredients for men running a structured training programme. Each 3-capsule serving delivers 600mg of KSM-66 Ashwagandha, 500mg of Fadogia Agrestis and 300mg of Shilajit Extract at a 10:1 concentration ratio. The bottle provides 30 servings.

KSM-66 at 600mg is the most-studied branded ashwagandha extract, standardised to 5% withanolides and clinically researched for stress modulation, recovery and hormonal support. Fadogia Agrestis at 500mg is the West African herbal extract that has gained attention through the natural testosterone optimisation conversation. Shilajit at 300mg from a 10:1 extract concentrates the fulvic acid and trace mineral profile that whole shilajit resin provides at lower potency.

What separates BUILD from a single-ingredient ashwagandha or fadogia bottle is the three-pathway combination at clinical-research doses in one capsule. Stacking KSM-66, Fadogia and Shilajit individually costs significantly more than the BUILD bottle. XL Nutrition own-brand consolidates the stack at a price that sustains the 90-day window the research literature suggests for these ingredients.

BUILD suits adult men on a structured strength or hypertrophy programme who want a multi-pathway natural support stack, lifters in their 30s and beyond who notice slower recovery, and anyone who would otherwise buy KSM-66, fadogia and shilajit separately. It is not designed for women, those on prescribed hormonal therapy, or under-18s.

Frequently Asked Questions

What does BUILD contain?

BUILD provides three ingredients per daily serving: 600mg KSM-66 ashwagandha (a standardised root extract of Withania somnifera), 500mg fadogia agrestis (a West African plant extract), and 300mg shilajit extract standardised to 50% fulvic acid. The 90-capsule bottle delivers 30 daily servings at 3 capsules per day.

When should I take BUILD?

Take 3 capsules daily with food, typically alongside your first meal of the day. BUILD is stimulant-free, so timing is flexible. Consistent daily use over several weeks is the typical pattern for plant-extract formulas like this one.

Can I stack BUILD with XL Creatine and XTRA Whey?

Yes. BUILD contains no creatine and no protein, so there is zero ingredient overlap with XL Creatine Monohydrate or XTRA Whey. The three products together cover plant-extract stack (BUILD), creatine monohydrate, and daily protein intake. This combination is also available as the XL Muscle Builder Bundle at a discounted price.
