Every way to take a peptide.
Peptides are the most talked-about thing in strength and recovery. Almost all of it happens in vials, sold by strangers, with no label anyone can check. People do it anyway. So we made a drink with a peptide that has been clinically studied in humans.
What's in the can.
2.4 g
The studied amount, in every can
Each can carries 2.4 g of hydrolyzed fava bean protein, the source of the peptides and the daily amount used in the human studies. That is why Spry exists.
Cloudy on purpose
A light haze from the fava bean protein, which settles a little in the can. Roll it once, then open.
Lightly sparkling. Low calorie.
Sweetened with monk fruit and stevia, plus a little cane sugar. It drinks closer to a dry citrus soda than a sports drink. Electrolytes include sodium, potassium and magnesium.
One peptide. Clinically studied.
Two placebo-controlled, peer-reviewed human studies of the fava bean ingredient in Spry, at 2.4 g a day, the amount in every can. Both are cited below.
Recovery after hard sessions
>2xfaster strength recovery than placebo*
Supports muscle recovery after training and helps reduce exercise-induced fatigue.
*Placebo-controlled, peer-reviewed human studies of hydrolyzed fava bean protein, the ingredient in Spry, taken as capsules at 2.4 g a day, the amount in one can. Strength: 72 healthy adults aged 19 to 40 on a resistance-training program, one-rep max leg extension at day 28 (Mohan et al., BMJ Nutrition, Prevention & Health, 2025). Recovery: 30 healthy men aged 30 to 45, rate of strength recovery over the 72 hours after a workout designed to cause muscle soreness (Kerr et al., Nutrients, 2023). These results are for the ingredient, not for Spry itself, and we are testing that the can keeps the ingredient intact.
Read both trials
It has to taste good, too.
Four flavors, lightly sparkling and low calorie. Pick one and the can changes.
Mango Passionfruit
The crowd-pleaser. Tropical and bright, with a tart edge.
Strong is a habit.
Not a heroic act. The stairs two at a time at forty-six, and the run club on a wet Tuesday. Showing up tomorrow because you recovered today.
The science that helps you keep that habit is real. Almost all of it is sold in vials, by strangers, with no label anyone can check. People buy it anyway, because nobody offered a better way.
So we took one ingredient that was studied in people, at the amount that was studied, and made a drink around it. We print what the studies found. Roll it once. Then get on with your day.

“I came to peptides as a user first. I wanted one that was studied in people and safe to drink, sold where I buy my groceries. I couldn’t find it, so we made it.”Alejandro Navarro, founder
Questions.

What is in it?
Lightly sparkling water, 2.4 g of hydrolyzed fava bean protein (the clinically studied ingredient) and electrolytes: sodium, potassium and magnesium. Sweetened with monk fruit and stevia, plus a little cane sugar. No artificial colors, flavors or sweeteners. Each flavor has its own ingredient list and Nutrition Facts, and both go on this page before we ship.
Why is it a little cloudy?
The light haze comes from the fava bean protein. It settles a little in the can, so roll it once, then open.
Is it a soda? A protein shake?
Neither. It is a lightly sparkling, low calorie drink built around one clinically studied ingredient, and it is not sweet the way a soda is.
Does it need to be refrigerated?
No. Store it in a cool, dry place. It tastes best cold.
Where do you ship?
The first run ships within the United States. Shipping is $5.99, and free on orders of $70 or more.
