Our dissolvable sticks use a proprietary formulation that allows the amino acid powder to dissolve completely in water without the need for a shaker bottle. Simply drop one stick into 300ml of water, stir twice, and it's ready to drink. The stick dissolves in about 10 seconds with no foam, grit, or residue.
Our products contain pure amino acids — BCAAs (leucine, isoleucine, valine), EAAs (all nine essential amino acids), and specialized blends like FlexAmino (glycine, proline, hydroxyproline). We use no artificial colors, no fillers, no maltodextrin, and no unnecessary binders. All ingredients are on the EU's permitted nutrient source list and are EFSA compliant. Full ingredient lists are available on each product page.

Yes. Every single batch is sent to independent, accredited laboratories for testing. We test for amino acid content (label accuracy), heavy metals (lead, arsenic, cadmium, mercury), microbial contamination, and dissolution time. No batch is released for sale until all tests pass. If you'd like to see the lab results for your specific batch, email us at support@amynostack.com with the batch number printed on your packaging.
Yes. We offer bulk and wholesale pricing for gyms, sports teams, and retailers. For orders of 10+ packs, contact us at support@amynostack.com for a custom quote. We're also developing a subscription service with a 15% discount for recurring orders — sign up for our newsletter to be notified when it launches.
Our amino acid supplements are free from common allergens including dairy, soy, gluten, and nuts. All products are manufactured in a facility that does not process any of the 14 allergens listed in EU Regulation No. 1169/2011. However, we always recommend checking the full ingredient list on your product packaging if you have specific sensitivities.
Store in a cool, dry place away from direct sunlight. The dissolvable sticks should be kept in their original packaging until use. Each stick is individually sealed for freshness. Do not expose to temperatures above 25°C or high humidity. The best-before date is printed on each pack — products remain at full potency until that date when stored correctly.
Our products are intended for adults aged 18 and over. Amino acid supplements are not recommended for children or adolescents unless specifically advised by a healthcare professional. If you are under 18, please consult with a doctor or sports nutritionist before using any dietary supplement.
Yes. All our products comply with EU Regulation No. 1169/2011 (Food Information to Consumers), EU Regulation No. 1925/2006 (Food Supplements Directive), and all relevant EFSA guidelines. Our ingredients are on the EU's permitted nutrient source list. Our facility is GMP-certified and registered with the Slovak food safety authority. We are fully compliant as a food supplement business operating within the EU.
We recommend consulting your healthcare provider before using any dietary supplement if you are pregnant, nursing, or planning to become pregnant. While our products contain only amino acids and no stimulants or banned substances, individual circumstances vary and a medical professional can give you personalized advice.
For optimal results, take BCAAs or EAAs around your training window — either 30 minutes before or immediately after exercise. Our dissolvable sticks are designed for post-workout use: drop one in water right after training for fast amino acid delivery to your muscles. On rest days, you can take one stick in the morning or between meals to maintain steady amino acid levels. See our recovery nutrition guide for detailed recommendations.
BCAAs (branched-chain amino acids) contain three amino acids: leucine, isoleucine, and valine. EAAs (essential amino acids) contain all nine amino acids your body cannot produce on its own, including the three BCAAs. While BCAAs are great for muscle recovery, EAAs provide a more complete amino acid profile for muscle protein synthesis. For a detailed comparison, read our article on BCAAs vs. EAAs.
