Our take on each
365 Organic Hemp Protein Powder
Best for: Plant-based eaters who want a clean, simple label
This is the no-frills, plant-based option for people who care more about what is not in the tub than about chasing the highest protein number on the label. It is organic hemp seed protein, unflavored, and carries USDA organic, non-GMO, and kosher certifications, so the ingredient list stays short and verifiable.
Hemp is a solid choice if whey does not agree with your stomach, or if you simply prefer to keep things plant-based, and at this price point you are not overthinking a purchase that could otherwise involve a lot of label reading. It comes in a 16 oz size that is easy to keep on a shelf without committing to a huge tub.
The honest tradeoff is flavor and focus. It ships unflavored, so it needs a smoothie or something to mask the taste rather than a plain shake with water, and it leans toward clean sourcing over the sheer protein-per-scoop numbers a dedicated whey isolate delivers. For a plant-based daily staple, it is an easy, affordable choice.
Optimum Nutrition Gold Standard Pro Gainer
Best for: Hard gainers trying to put on size
Pro Gainer is built for one job: helping you eat more without choking down extra meals throughout the day. Each serving stacks 650 calories, 60g of protein, and more than 80g of carbs, which is the kind of math that actually moves the scale for someone who struggles to eat in a surplus.
It comes from Optimum Nutrition's Gold Standard line, so the brand pedigree behind the formula is well established, and for a genuine hard gainer, someone who trains hard but cannot out-eat their metabolism, this solves a real problem that whole food alone often does not.
Be clear-eyed about who this is for, though. This is not a powder for someone trying to lean out, the calories and carbs are the entire point, not a side effect, so using it while cutting works directly against your goal. It also carries the highest price of the three picks here. For skinny lifters trying to bulk, it does exactly what it promises.
