Creatine + BCAA blend
Creatine monohydrate with 2:1:1 branched-chain amino acids
Dry blend of creatine monohydrate (CAS 6020-87-7) with L-leucine, L-isoleucine and L-valine at 2:1:1. Standard build puts 3 g creatine and 5 g BCAA in an 8 g serve. Vegan and free of major allergens.
Specifications
| Product type | Dry physical blend of four chemically defined actives. Not a separate chemically defined compound, so Chapter 29 is closed to it by Note 1 to that chapter. |
| Standard composition (w/w) | Creatine monohydrate 37.5%, L-leucine 31.25%, L-isoleucine 15.625%, L-valine 15.625%. That is 3 g creatine and 5 g of 2:1:1 BCAA in an 8 g serve. |
| Creatine identity and assay | Creatine monohydrate, CAS 6020-87-7, C4H9N3O2.H2O, MW 149.15, 87.9% creatine base. USP assay 98.0-102.0% on the dried basis; lots typically 99.0% and above. |
| BCAA identity and assay | L-Leucine CAS 61-90-5 and L-isoleucine CAS 73-32-5, both C6H13NO2, MW 131.17; L-valine CAS 72-18-4, C5H11NO2, MW 117.15. Each not less than 98.5%, dried basis. |
| Creatine purity limits | Creatinine not more than 100 mg/kg, dicyandiamide not more than 50 mg/kg, dihydro-1,3,5-triazine not detectable, per the EFSA 2004 AFC opinion specification. |
| Appearance | White to off-white odourless free-flowing crystalline powder. A yellow cast or caking indicates moisture exposure and is grounds for rejecting the lot. |
| Solubility in water at 20-25 degrees C | Creatine monohydrate approx. 13 g/L; L-leucine approx. 22 g/L; L-isoleucine approx. 34 g/L; L-valine approx. 85 g/L. A full serve makes a suspension, not a solution. |
| Particle size | 80 mesh (approx. 180 micron) standard across all four components. A 200 mesh micronised creatine grade and a lecithin-instantised blend are available to order. |
| Moisture and stability | Creatine loss on drying 10.5-12.5% is water of crystallisation, theoretical 12.1%. Creatine converts to creatinine in warm, moist or acidic liquid; avoid low-pH RTD work. |
| Purity and microbiology | Lead, arsenic, cadmium and mercury reported individually against USP <232> and <233>. Total plate count max 1,000 cfu/g; Salmonella and E. coli absent. |
| Origin and production route | Creatine is synthetic from sarcosine and cyanamide, non-animal. The three amino acids are fermentation-derived on non-animal media; route stated on each lot certificate. |
| Allergen status | Free of milk, egg, soy, fish, crustacean, gluten, peanut and tree nut. Vegan and vegetarian, with no bovine, porcine, gelatin or marine input. Halal and kosher on request. |
| Shelf life and storage | 36 months unopened below 25 degrees C, dry and out of direct sunlight. Creatine and free amino acids both pick up moisture; reseal the liner immediately after sampling. |
| HS code | 21069099 (India ITC-HS) for the finished blend. Not the sheet's 21061000, and not Chapter 29; see the classification note. |
This is a dry blend of four chemically defined actives, not a compound in its own right: creatine monohydrate (CAS 6020-87-7) with L-leucine, L-isoleucine and L-valine held at the conventional 2:1:1 ratio. The standard build is 37.5% creatine monohydrate and 62.5% BCAA by weight, which puts 3 g of creatine and 5 g of branched-chain amino acids into an 8 g serve. Other splits are blended to order, including 1:1 and 1:2 creatine-to-BCAA ratios and leucine-weighted 4:1:1 or 8:1:1 BCAA fractions for brands that want the leucine figure to lead the panel.
Creatine monohydrate assays 98.0-102.0% on the dried basis against the USP monograph and carries 87.9% creatine base, the balance being water of crystallisation, so a loss on drying of 10.5-12.5% is normal and not a defect. The purity limits that matter are the ones set out in the EFSA 2004 AFC opinion on creatine monohydrate: creatinine not more than 100 mg/kg, dicyandiamide not more than 50 mg/kg, and dihydro-1,3,5-triazine not detectable. Each amino acid assays not less than 98.5% on the dried basis. Because creatine converts to creatinine in warm, moist or acidic liquid, the blend is specified for dry formats and shaker use; any ready-to-drink low-pH application needs its own stability work before a shelf life is committed.
Solubility is the practical constraint on the format. Creatine monohydrate is only slightly soluble at roughly 13 g/L and L-leucine sits near 22 g/L, so an 8 g serve in 300 mL of water forms a suspension rather than a clear solution. A 200 mesh micronised creatine grade and a lecithin-instantised blend both improve the in-glass result. On origin, the creatine is synthetic, made from sarcosine and cyanamide with no animal input, and the three amino acids are supplied as fermentation-derived grades produced on non-animal media, with the production route stated on each lot certificate. The blend is free of milk, egg, soy, fish, crustacean, gluten, peanut and tree nut, and is vegan with no bovine, porcine, gelatin or marine material.
