PHARMACEUTICAL GRADE ONLY

Every ingredient in a XANDRO LAB formula is pharmaceutical-grade, sourced from suppliers we select for rigor, not price. Here's how we choose them, and what we require before an ingredient earns a place in a formula.

EFFICACY OVER "HIGH" DOSAGE

A high number on a label doesn't mean much if the ingredient behind it is poorly absorbed. We don't chase the cheapest available raw material or the highest milligram count.

We look for high-absorption forms (microencapsulated, liposomal) backed by real scientific rigor, because a smaller dose of an ingredient your body can actually use outperforms a larger dose of one it can't.

How We Qualify Ingredients

SOURCING STANDARDS
HIGH PURITY

Every batch is screened for lead, arsenic, cadmium, and mercury against USP and international limits. These metals accumulate in the body with repeated exposure, so a supplement you take daily has to clear a stricter bar than something you eat once.

HIGH ABSORPTION

Independent labs check for bacteria, yeast, mold, and pathogens like E. coli and Salmonella. Contamination from poor manufacturing or storage isn't something you can see or taste, which is exactly why it gets verified rather than assumed.

PURE ENCAPSULTION

Pair text with an image to focus on your chosen product, collection, or blog post. Add details on availability, style, or even provide a review.

INDUSTRY LEADING CERTIFICATIONS

We test how each formula holds up over time and across storage conditions, so the potency on day one is still close to the potency on the day you take your last dose.

RELIABLE SUPPLY

High-Performance Liquid Chromatography measures the exact amount of active ingredient in each batch, down to the milligram. This confirms what's on the label matches what's actually in the capsule.

DIRECT FROM MANUFACTURERS

We buy directly from manufacturers, not brokers or distributors, across France, Japan, China, India, the US, and beyond. These are long-term relationships, not one-off purchase orders, which means consistency in what we get batch over batch.

Co-development, not just procurement: In some cases, we work directly with a manufacturer's product and science team during formulation itself, not just at the point of purchase.

Lysoveta, the omega-3 form used in LPC NEURO, is one example. We aligned with their science team on the product's development, not just sourced the finished ingredient.

THE SOURCING PROCESS
1. SAMPLING

A candidate supplier's raw material is requested and reviewed before any commitment.

2. COA REVIEW

The supplier's Certificate of Analysis is checked against our purity and quality requirements.

3. RAW MATERIAL TEST

the sample itself is independently evaluted, not just the paperwork.

4. FORMULATION TEST

The ingredient is tested inside a draft formulation, to confirm it performs as expected alongside the rest of the formula, not just on its own.
