Acetic acid is a diluent, not a research compound: a 0.6% sterile solution supplied premixed in 3 mL and 5 mL. IGF-1 family peptides sit near their isoelectric point at neutral pH, so they aggregate or precipitate in bacteriostatic water, and the lower pH of this solvent is what holds them in true solution. It is the difference between an IGF-1 LR3 vial that reads clear and one that reads hazy.
- It is a solvent, not a peptide: 0.6% sterile acetic acid, premixed and ready.Product spec
- IGF-1 family peptides have isoelectric points near neutral pH, so they aggregate or precipitate in bacteriostatic water.Peptide Guide p.12
- IGF-1 LR3 and related peptides are documented as requiring an acidic solvent rather than bacteriostatic water, which is what this 0.6% solution supplies.Peptide Guide p.12
- Haze reads differently by compound: for acid-loving peptides it is simply undissolved material, but for anything that should go clear in BAC water new cloudiness signals aggregation, degradation or contamination.Peptide Guide p.12
