Peptide Guide: How to Read and Understand the Package Insert

Every time you buy peptides on the Internet or from local retail stores, it will always come with a package insert, which always accompanies each drug purchase from any store. The package insert is the certification, which must be present in all drugs and it contains basic, but vital information about the drug, in this case, the peptide you just bought.

The purpose of the insert is to teach you how to read the instructions in a simple manner so you can understand quickly and effectively. It is like the identity card of the peptide.


The first thing you should focus on in the package insert is the name of the peptide. This may include the generic name, the chemical name and the trade name. The second item will be the picture of the peptide and its structural formula. You should pay keen attention to the formula as it will determine whether it was the real peptide you have hoped to buy. If the formula is different from what you had hoped to buy, then you should not consider using that peptide.

The next item to look at in the package insert is the ID number, or the approval number of the peptide. This should be unique to the peptide and in case you have any complaints about the peptide, it is this number, which you will submit to authorities for further investigation. Kindly note that it is a must for the drug to have an ID number, without which it may imply that the peptide was not approved by authorities and is in the market illegally. It would be dangerous to go ahead and use peptides without this approval number.

You will also find the date of manufacture or synthesis of the peptide as well as the expiry date. The expiry dates of peptides will always be years away, and most can last for a very long time if you can ensure proper storage.
