Price and refund terms
At the documented single-purchase price, Boostaro is $69.00 and Prostastream is $69.00. The two prices are identical in our captured data. Refund terms: Boostaro 60-day refund window; Prostastream 60-day refund window. A longer window reduces the risk of a failed experiment, but it does not make the formula better. The Value component of the score accounts for both the price relative to the category median and the refund window.
Formula and transparency
Boostaro lists 7 named ingredients: Vitamin C, Vitamin K2, L-Citrulline, L-Lysine HCl, Pine Bark Extract, Magnesium Citrate, Nattokinase. Prostastream lists 8 named ingredients: Saw Palmetto, Maitake, Reishi, Shiitake, Graviola, Cat's Claw, Pygeum Africanum Bark, Stinging Nettle Root. The two formulas do not share any named ingredients in our data. Only Boostaro lists Vitamin C, Vitamin K2, L-Citrulline, L-Lysine HCl, Pine Bark Extract, Magnesium Citrate. Only Prostastream lists Saw Palmetto, Maitake, Reishi, Shiitake, Graviola, Cat's Claw. Boostaro has 1 documented red flag: exaggerated-claims. Prostastream has 1 documented red flag: exaggerated-claims. Ingredient order and blend totals are not the same as per-serving doses; without a Supplement Facts panel, part of the formula remains unknown. A longer ingredient list is not automatically a better formula; disclosure, dose and evidence quality matter more than the count.

Who should consider Prostastream
Consider Prostastream if the documented profile fits you: the page positions it for Adult men comparing prostate-support supplements.

What would change this verdict
This verdict is not permanent. It would change if a product publishes per-ingredient doses, removes a documented red flag, changes its price or refund window, or adds a product-specific trial. Today, the documented refund gap is 0 days and the score gap is 0.0 points; either can change with the next data refresh. We capture data daily and recompute the score after each refresh; the comparison page follows the data. If you spot a value that no longer matches the official page, report it through the contact page and we will verify it against the source.
