Give it time
From dairy lot to sealed tub — shown, not claimed.
Imported whey, traceable per lot
Every batch starts with US and EU dairy whey shipped with its Certificate of Analysis. Lot numbers stay attached from intake to pack.
GMP-certified facility
Blending, sieving and filling happen in a temperature-controlled GMP and FSSAI licensed plant with documented cleaning between runs.
In-house QC on every batch
Moisture, assay and dispersion checks run before a batch is cleared. Anything off-spec is quarantined, not shipped.
Third-party lab verification
Independent NABL-accredited labs verify protein content, amino profile, heavy metals and microbes. Reports are published per batch.
Tamper-evident, code-verified
Each tub is sealed, coded and scannable. One scan on the pack lets you track the lab report and whether it is genuine.
