Customer Reviews
Decent Muscle Gainer
I bought the Muscle Gainer and a free shaker. The product itself feels good quality and I've seen some results. Delivery took about 5 days to reach Pune, which is okay but not super fast. Customer service was a bit slow to respond to my query about tracking but eventually got through. Overall, a decent experience, but delivery could be quicker.
Good quality, fast delivery
I ordered the Whey Protein Isolate during their Republic Day sale. The website was easy to navigate and placing the order was smooth. It reached me in Chennai in just 3 days, which was quicker than I expected. The product mixes well and tastes decent. No complaints there.

Hey guys, thinking of ordering some whey from Big Flex. Anyone know how long it usually takes for them to deliver to Bangalore? Need it kinda quick.
