Build Muscle*

Recover Faster*

BIO-GRO™ from iSatori is a ground-breaking
sports supplement like no other. iSatori is the first to introduce a new breed of designer supplementation
called Bio-Active Peptides. You can think of BIO-GRO as "fertilizer for your muscles." The ultra-concentrated BIO-PRO® Bio Active Peptides found only in BIO-GRO work best when taken daily and should be the base of any serious trainer’s program. BIO-GRO is the true catalyst to help drive lean muscle growth, improve strength and decrease recovery time.*

When taken daily in the correct amount for your bodyweight, BIO-GRO has been clinically studied to decrease recovery time and DOMS, as well as increase mass and ramp up strength on the leg press and bench press… and that is with trained individuals.*

BIO-GRO is instantized for easy mixing, sugar-free, gluten-free and stimulant-free and is perfect to add to your muscle-building or weight-loss program (when you are trying to maintain muscle). BIO-GRO is truly the next generation in performance-based supplements, and can be used by men and women alike.

What are Bio-Active Peptides?

The engineered Bio-Active Peptides (or BAP's) found only in BIO-GRO use a world-leading manufacturing method, whereby cleaved protein fragments are extracted from the highest grade bovine colostrum, which are then centrifuged and micro-concentrated to form a low molecular weight, highly bioavailable powder, yielding an exact concentration of bioactive: Proline-Rich Peptides (PRPs), Growth Factors (i.e. Fibroblast-GF), Immunoglobulins and Lactoferrin.

Why should I use BIO-GRO?

There are five reasons you should use BIO-GRO:

1. Concentrated and powerful. A highly concentrated form of Bio-Active Peptides means less out-of-pocket expense for you, and more results. That is because one small scoop (1.5 grams) of BIO-GRO contains bio-active peptides that triggers protein synthesis, muscle-building, increased strength, and recovery can be dramatically improved.*

2. More convenient. Unlike bulky tablets and sugary powders, BIO-GRO is an unflavored powder in its raw form that is virtually tasteless. Now instantized, BIO-GRO mixes well in liquids like water or your protein shake as well as foods like oatmeal and yogurt. It is truly an easy-to-use ergogenic aid.

3. More scientific research. There are numerous published clinical abstracts and studies that back up the demonstrated benefits of the primary ingredient in BIO-GRO. And more importantly, these studies were conducted mostly on well-trained athletes, participants who traditionally show less positive effects compared to untrained individuals.

4. More expert opinions. There hasn't been a supplement we can think of, to date, that has had more PhD-sports nutrition experts who independently support and validate the science and effects behind the primary ingredient in BIO-GRO. Including such highly reputable names as Darryn Willoughby, PhD; Jeffrey Stout, PhD; Jay Hoffman, PhD; and David Sandler, ABD-PhD.

5. Highest quality. Because iSatori controls the domestic source of our ingredient and has engineered the first micro-concentrated, low molecular weight Bio-Active Peptides found in BIO-GRO, you can trust and count on every batch being of the highest quality and consistency; and what's more, each batch is GRAS certified, HALAL, Kosher, and produced right here in the USA.

Who should use BIO-GRO?

BIO-GRO should be used by anyone who is interested in developing or maintaining more lean body mass and enhancing recovery from exercise or sport. BIO-GRO is also recommended for those looking to maintain muscle while on a calorie-restricted diet.* This would include bodybuilders, fitness, figure, or physique competitors; and athletes competing in any sport at all levels.

Can women use BIO-GRO?

Absolutely! Many athletic women already do. Because BIO-GRO contains almost zero calories, zero fat, zero sugars and zero gluten, it is perfect for dieters or women who are calorie- or carb-conscience yet want the bioactive benefits of protein to help develop and maintain lean body tissue. And BIO-GRO requires only one tiny scoop (1.5 grams) that has well-documented scientific results on top of the mountains of anecdotal evidence from users. What's more, BIO-GRO is derived from a natural source and is safe for healthy individuals to consume.*

Supplement, not steroid. It simply helps you get the most of your protein shake. It's not a necessity but a nice product to have. If you don't get as much protein as you should, I would recommend doing that instead

Verified Buyer

This stuff is great. You can tell immediately the next day. Gains show in quickly. People who complain about not seeing result are most likely not getting close to their protein intake. I almost mix it with milk after my workouts and put it in my Greek yogurt and gronola mix. Will be buying more

This product is a game changer! First off, the unflavored is amazing because its seriously UN-flavored. I put this good-good in fage 0% yogurt, bean soup, mixed in a smoothie or shake, oats in the morning-- seriously UN-flavored. Helps me absorb the maximum amount of protein I can and maintain lean body mass. This is no joke, you have a serious pump going from the night before and you will see it the next day, but minus the aches and pains. So much more motivation that i can get into the gym and put up some serious weight without having to recover for three days or lower my weight. The "gro" in bio-gro is some serious business marketing - started seeing positive muscular changes as well as a slight decrease in extra fat.

I have added bio-gro on and off of my routine but now realized that including it into my daily regime is a must. I started taking this about 2.5 years ago during my first bikini prep. It helped me maintain my lean mass while cutting. I then stopped taking it during another prep and had noticed that I didn't maintain my mass as much as the first time. I began taking it again and noticed a huge difference in the way I was able to put on muscle. Love this supplement.
