Peptides and similar compounds — no advertising, no scaremongering

Using the manufacturer ZPHC as an example, we look at what is known about popular peptides: what the manufacturer says, what animal and human studies have shown, what people who have tried them report — and which risks are worth knowing in advance.

How this site works

We do not sell peptides and we do not work for the manufacturer. ZPHC is used as an example because most of the substances covered here are sold under this brand — but every page is equally fair to the manufacturer and to its critics.

Every statement on the site is backed by a link to a source: a regulator, a scientific publication, the manufacturer's label or a real user report. If there are no human studies on a substance, we say so plainly instead of filling the gap with marketing.

1

The regulator's position (FDA/EMA) — wherever one exists.

2

Animal and human studies — kept separate, never mixed.

3

Real user reports — positive, neutral and negative, with links.

4

Risks and contraindications — neither downplayed nor exaggerated.
