Formulation
Amino spiking found
The same Trustified report says amino spiking was found and specifically references L-Arginine.
Testing
Independent blind-test failure
Trustified reports that Bigmuscles Nutrition 100% Performance Whey failed blind testing.
Informed Choice withdrawn (Premium Gold Whey)
LGC Informed Choice shows Bigmuscles Nutrition Premium Gold Whey as withdrawn (22-Oct-2025). Marketing that still implies active Choice coverage is outdated.
