Our Story
AmynoStack was founded in 2023 by a team of sports nutritionists and competitive athletes tired of clumpy, chalky amino powders that never fully dissolved. We set out to make clean, dissolvable amino acid supplements that actually mix into water without a shaker bottle.
Our dissolvable stick technology took 18 months to develop. Each stick contains pure, third-party-tested amino acids in ratios backed by current sports nutrition research. Drop one in 300ml of water, stir twice, and it's ready. No foam, no grit, no residue.

Certifications
GMP Certified
Good Manufacturing Practice certification for our Slovak production facility.
Third-Party Lab Tested
Independent testing for purity, heavy metals, and label accuracy on every batch.
EFSA Compliant
All ingredients are on the EU permitted nutrient source list.
Manufacturing Process
Our manufacturing process starts with sourcing pharmaceutical-grade amino acid raw materials from EU-certified suppliers. Every incoming raw material is quarantined and tested for identity and purity before being released for production.
The dissolvable stick formulation is produced in our GMP-certified facility in Bratislava. Amino acid powders are blended in precise ratios using validated mixing protocols to ensure uniform distribution. The blend is then portioned into individual dissolvable sticks using automated filling equipment, with each stick weighed to ensure dosing accuracy within ±2%.
Finished products are held in quarantine until third-party lab testing is complete. Each batch is tested for amino acid content, heavy metals (lead, arsenic, cadmium, mercury), microbial contamination, and dissolution time. Only after all tests pass is the batch released for sale.
Every product carries a batch number and best-before date. We retain samples of every batch for two years for traceability. If you ever have a question about a specific batch, email us at support@amynostack.com with your batch number and we'll send you the lab results.
Our Promise
If a stick doesn't dissolve cleanly, send us a photo and we'll refund it. No questions. We built this brand on the promise that amino supplements shouldn't require a cocktail shaker to use.
