3.2g D-ASPARTIC per serving

Applied Nutrition Testosterone Support TRT 300g is a comprehensive natural testosterone-support powder built for adult men running structured training programmes. Each 10g serving delivers 3.2g of D-Aspartic Acid, 500mg of Maca Root Extract 10:1, 500mg of Shilajit Extract 20:1, 300mg of Ashwagandha Root Extract 10:1 and 12mg of zinc, alongside Tribulus, Broccoli Sprout Extract, Irish Sea Moss, magnesium, vitamin D3 and vitamin C. The 300g tub provides 30 servings.

D-Aspartic Acid at 3.2g matches the dose used across the published research on natural testosterone support. Maca and Shilajit at concentrated extract ratios deliver clinically-relevant adaptogenic and trace-mineral doses. Ashwagandha at 300mg from a 10:1 extract sits at the standard clinical range for cortisol modulation. Zinc at 12mg (120% NRV) contributes to the maintenance of normal testosterone levels in the blood and to normal fertility and reproduction (EFSA-authorised under Regulation 432/2012). Vitamin D3 at 5μg contributes to normal muscle function.

What separates TRT 300g from a single-ingredient natural-test product is the multi-pathway approach. DAA targets the hormonal pathway, ashwagandha targets stress and cortisol, the trace minerals from sea moss and shilajit support the foundational mineral profile, and zinc plus D3 cover the authorised-claim regulatory base. Trainees who would otherwise buy each ingredient separately get the full stack in one daily powder serving.

TRT 300g 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 want adaptogenic support, and athletes managing the stress load of high-volume training. Not for women, those on prescribed hormonal therapy, under-18s, or trainees who only want one ingredient in isolation.

Alternative: XL Nutrition Testosterone Booster 90 Caps (16.2mg zinc, 336mg magnesium, 1200IU D3) for trainees wanting an EFSA-led capsule-format testosterone-support stack.

Frequently Asked Questions

How much D-ASPARTIC ACID is in each serving of Testosterone Support TRT?

Each serving of Testosterone Support TRT declares 3.2g of D-aspartic acid on the label. Alongside the headline dose, the label also declares 500mg of maca root 10:1, 500mg of shilajit 20:1, 300mg of ashwagandha root extract 10:1, 250mg of tribulus terrestris, 200mg of broccoli sprout extract and 12mg of zinc, plus a full B-complex and vitamin D3. The full label is published on this product page so you can cross-check before stacking it with anything else.

When should I take Testosterone Support TRT?

Testosterone Support TRT is best taken in the evening, away from caffeine. Consistent use over time tends to do more than precise timing, so build it into a daily routine and let the habit do the work. Pair it with a balanced diet and a structured training plan, since supplements deliver against an existing stack, not on their own.

Is Testosterone Support TRT third-party tested?

Testosterone Support TRT is manufactured by Applied Nutrition in their UK facility. Many Applied Nutrition ranges carry Informed Sport batch testing for banned substances, so check the on-pack badge if Informed Sport status matters for your federation. The full ingredient breakdown and allergen disclosure is published on this product page, so you can review what is on the label before adding it to your stack.
