Peptides are available in three major forms – as solutions, in powder form and as pills. As such, it is not only ingestion that varies, but also their bioavailability. Bioavailability refers to the percentage of the peptide that is actually absorbed in the body. This is usually a critical factor worth considering every time you are buying your peptides.
The efficacy of any nutrient ingested in the body is heavily dependent on the bioavailability of that particular nutrient and the same is also the case when considering peptides. It implies that highly bioavailable peptides will be digested and absorbed faster, thus making them more effective in the body.
Peptides in liquid form have the highest possible absorption rate into the body, because their composition makes them essentially pre-digested. This is not the same experience you will have when using peptides in powder form or those ingested as pills. It is because of this very reason that performance athletes prefer to inject themselves with peptide solutions instead of taking them as pills.
For peptides in pill forms, they take relatively longer to attain the levels of efficacy as those taken in liquid forms. This is because the entire composition of the powder or the pill is never made up of 100% peptides. The body will have to ingest and assimilate the peptide from the powder or pill and this is a process that is bound to take some time.
For peptides in powder form, they need to be mixed with juice or water before they are ingested. Their efficacy is higher than that of those in pill form since they will not require a lot of digesting before the peptide is assimilated into the body.
In conclusion, the specific form of peptide taken may depend on a number of factors, but as it stands, the majority prefer peptides in liquid forms because they are convenient and more effective.
