However, these reports do not prove that a named peptide caused each event.

A report has no comparison group and may leave key facts uncertain. Product labels may be wrong, while contamination or impurities may add another exposure.

By contrast, a peptide stack adds more variables at once. Each vial may have a separate identity, sterility and concentration problem. Meanwhile, overlapping biological effects can change symptoms or laboratory results.<\/p>\n    <p>Popular combinations have another evidence gap: researchers have not tested most online stacks in controlled human safety trials.

In the EU and wider EEA, EudraVigilance manages reports of suspected adverse reactions linked with authorised medicines and medicines studied in clinical trials. Likewise, national regulators collect and assess reports.<\/p>\n    <p>Yet spontaneous reports do not prove causation. The EMA warns that a reported event may be coincidental. Moreover, report counts do not show how likely an event is.
