Good Whey Isolate purchase

Bought the Whey Isolate. Delivery took 6 days to reach Sacramento. Product dissolved well, tasted fine. Price was reasonable for a low-sugar protein. No issues.

Consistent quality, fast shipping

This was my third order from 3721. I grabbed some more Creatine and a Shaker Bottle. Like before, shipping was quick, got to my place in Boston in about 5 days this time. The quality is always reliable, which is why I keep coming back. My previous BCAA order was good too. Their stuff always mixes easily, no complaints there. Glad to see they keep up the good work.

Hey, thinking about grabbing some stuff from 3721 Nutrition. Anyone know if their protein powders are actually any good? Like, compared to Myprotein or something?

Yeah, I tried their whey isolate last month. Tastes pretty decent, not super sweet which I like. Feels pretty clean too, good quality for sure.

I've used both 3721 and Myprotein. 3721 feels a bit more premium, especially the low-sugar options. Myprotein is fine, but sometimes the flavors can be a bit much. Plus, 3721 being from HK makes me feel a bit more connected, idk.

quick question: for first-time buyers, is there usually a discount code floating around? don't wanna miss out if there's one for new customers.

D Dana 4 months ago
Yeah, usually. I got like 10-15% off my first order. Keep an eye out for influencer codes too, they're pretty common and sometimes give a bit more.

I think so, I remember seeing something about a first-time purchase deal. Check their site or maybe google around for '3721 Nutrition KOL code', those usually work.
