“Animal studies prove it works in humans.”

Animal and cell studies are useful for mechanism and hypotheses, but routinely fail to translate. Differences in dosing, physiology, and study quality mean an effect in rodents may be smaller, absent, or harmful in people. Preclinical ≠ proven.

“Research peptides are automatically safe because they're peptides.”

'Peptide' is a chemical category, not a safety category. Some peptides are well-characterized approved drugs; many research compounds have little or no human safety data at all.

“Higher purity means sterile and safe.”

Purity is a chemistry measure — the fraction that is the intended molecule. It says nothing about sterility, endotoxin contamination, correct identity, or clinical safety. A '99% pure' label answers one narrow question.

“If it's natural or endogenous, it has no risks.”

Many peptides occur naturally in the body, but supraphysiologic doses, impure preparations, and unstudied long-term use all carry risk. 'Natural' does not mean risk-free.

“If influencers or athletes use it, it must work.”

Popularity and anecdote are not evidence. Visible use says nothing about whether a compound does what's claimed, or whether it's safe.

“All GLP-1 drugs are the same.”

They differ in which receptors they engage (GLP-1 alone vs. dual or triple agonists), in pharmacokinetics, and in their evidence base. They are related, not interchangeable.

“More growth hormone is always better.”

Growth-hormone signalling is tightly regulated; more is not simply better and can carry real risks. Secretagogues alter the body's own release rather than supplying a 'more is better' dial.

“Peptides aren't drugs.”

Pharmacologically active peptides used to affect the body are drugs in every meaningful sense, and many are regulated as such. 'Research-use-only' labeling reflects regulatory status, not harmlessness.

“A Certificate of Analysis proves it's safe to use.”

A COA reports batch chemistry (identity, purity). It is not evidence of sterility, clinical safety, or efficacy, and it does not make a research compound approved for human use.
