AUSTROPEPTIDE will never sell a peptide that is less than 98% in purity from our catalog section. Many of our smaller peptide chains are well into the 99% purity range. We have manufacturing abilities that are quite often beyond the scope of smaller companies and therefore are able to achieve very high purity levels. Proteins such as IGF-1 LR3 are always receptor grade and always above 95% purity.

Peptides, due to their nature, come in a variety of sizes and shapes. Normally after the lyophilization process has completed we have a peptide that is in a perfect cake. However there are times when it may break in transit or simply appear differently. This in no way effects the quality or potency of the product. It is simply an aesthetic issue. While we do try to always present a product that looks perfect, on occasion this isn’t possible.

Proteins are very large in size and due to the requirement of a buffer will appear larger in size than a mod grf or ghrp. This is also normal.

The purity level indicated on a COA is simply a measurement of aminos that made it into the proper chain to form the peptide. The left over 2% are simply aminos that, for what ever reason, didn’t make it into the proper sequence.

Peptides and Research serums are manufactured and sold to be used in a laboratory research setting. None of our products are intended for, nor are they manufactured for, diagnostic or therapeutic purposes in humans. Strong Peptide reserves the right to require additional verification of proper intent prior to fulfilling orders. Any orders that we feel aren’t for the specific intended purpose laid out in our Terms and Conditions will be denied.  Truthfully, if you are asking this question then you shouldn’t be ordering from AP PEPTIDES.

Because peptides are hygroscopic, warm up the peptide to room temperature in a desiccator prior to opening and weighing out the portion of the peptide to be used. Failure to do so can cause condensation to form on the product when the bottle or vial is opened and greatly reduce the stability of the material. Weigh out quickly in a clean environment only the needed quantity of the peptide to be used to minimize contamination and reseal container tightly. Store all unused peptide at -20° C or less in a sealed container with desiccant. Storage under these conditions will reduce and prevent bacterial degradation, secondary structure formation, and oxidation for up to several years. Sequences containing cysteine, methionine, tryptophan, asparagine, glutamine, and N-terminal glutamic acid will have a shorter shelf life than other peptides.

When solubilizing the peptide, please use the recommended solvents outlined in the solubility test provided by AP if your experimental conditions will allow it. Sonication is often helpful to dissolve the peptide. In general, sterilized water is the preferred solvent, but acidic peptides will dissolve in a basic buffer and basic peptides in an acidic buffer as determined by the amino acid sequence of the peptide. Peptide sequences containing Cys, Met, and Trp require oxygen free solvents as they are especially prone to oxidation. Peptides in solution are much less stable than lyophilized form and will remain viable for a much shorter period of time. As such, it is not recommended to store peptides under these conditions, but if absolutely unavoidable, the peptides in solution should be kept at -20° C using sterile buffers at pH 5-6 to prolong shelf life.
