1L + 450ml protein shaker set review: two sizes, one buy

Two bottles at two different sizes, plus a compartment for powder, for around the price of one mid-range shaker. The set solves a problem most single bottles can’t.

Two sizes beat one compromise size

Every single shaker is a compromise. Buy 400ml and it’s tight for a double scoop; buy 1L and you’re carrying a heavy bottle on days you only wanted one shake.

This set gives you both ends instead. The 450ml handles a standard single serving, where a scoop of whey goes into roughly 200ml to 300ml of water and the rest is the air the shake needs to mix properly. The 1L takes a double scoop, a mass gainer, or a shake plus the water you’ll drink alongside it.

In practice that means grabbing the small one for a normal gym session and the big one for a long training day, rather than owning one bottle that’s wrong half the time.

The compartment is for the second serving

The built-in storage compartment screws onto the bottle and holds dry powder. It’s aimed at anyone who trains away from home: pre-measure a scoop, carry it dry, and mix it when you need it rather than carrying a shake that’s been sitting for hours.

That’s genuinely useful for anyone who takes a second serving at the office or trains straight after work. It also stores creatine or capsules, which saves carrying a second container.

Around ₱135 for the pair, with a no-brand caveat

At around ₱135 as of August 22, 2026 for both bottles and the compartment, this is among the best value in the category by volume of plastic alone. It holds a 4.9 Shopee rating across 1,835 ratings with 7K+ sold, a solid base for a no-name product.

The caveat is exactly that: no brand stands behind it, so consistency between units varies, and the parts most likely to disappoint are the lid seals and the compartment thread. Test both with water before you trust them in a bag. Neither bottle includes a mixing ball, so thick powders will rely on your shaking.

The 1L is bulky when full, which is the honest cost of having it.

Who the set suits

Buy this if your sessions vary, if you want to carry a dry second serving, or if you’d rather own two bottles than keep washing one. It’s also a sensible first purchase if you don’t yet know which size suits you, since you get to find out.

Skip it if you only ever take one scoop and want a single well-made bottle, or if a branded build matters to you.

If one bottle is enough
