OptimalAmino® is a clinically-studied, free-form essential amino acid formula that gives your body what it actually needs to build and repair protein, without the calories, carbohydrate, or fat that come with dietary protein. OTG puts a full serving in a single stick pack, pre measured and pocket sized, in a variety of five flavors.
The OptimalAmino® OTG Fitness + OptimalStack Bundle is two Variety boxes of 30 stick packs, enough for 2 servings a day for a month. It's built for people who train regularly or use time restricted eating. It also includes a 30 serving container of OptimalStack® (Unflavored), our NSF Certified for Sport® creatine and HMB stack, for 1 serving a day alongside your OptimalAmino®.

No more struggling to hit protein goals or macro targets. One stick pack of OptimalAmino® OTG (13g) provides the usable protein equivalent of:
- 58g of protein from whey, dairy, nuts, or soy*
- 30g of protein from meat, poultry, or fish*
- 20g of protein from whole eggs*
That's 10g of essential amino acids without calories, carbs, fat, or sugar.

Suggested Use
Suggested Use
Mix 1 stick pack into 12 to 16 oz of cold water. Add the water first to avoid clumping, and the colder the water, the better it tastes.
Most people take 1 to 4 servings a day depending on age, body composition, and training load. Space servings at least 3 hours apart and between meals, so each one lands in a gap where you'd otherwise take in no protein.
For exercise recovery, take 1 stick pack 30 minutes before resistance training or within 30 minutes after endurance exercise. On hard training days or days with little dietary protein, take up to 4. Consult your physician before exceeding 4 servings a day.

One 9.75g serving of OptimalStack® contains:
- 5g Creapure® (99.99% pure micronized creatine monohydrate, made in Germany)
- 3g myHMB® (calcium β-hydroxy β-methylbutyrate monohydrate)
- 18.75mcg (750 IU) vitamin D3
Creapure® is the most widely studied form of creatine and is produced only by Alzchem in Trostberg, Germany. HMB is a metabolite of leucine; your body converts only about 5% of leucine to HMB, so a meaningful dose is hard to get from food.

- MGMichael G.Verified Buyer1 week agoRated 5 out of 5 starsGreat product!
I love Optimal Amino and Optimal Stack. I use both personally and with clients in my concierge medical practice. I don’t mind any of the variety pack flavors, and it’s much easier for me to drink them than take 10 of the big tablets.
