Cut through the noise: here are the peptides people are genuinely using most right now, by goal — and a reminder that popular isn't the same as right for you.
The most widely used research peptides right now are the GLP-1 class (semaglutide, tirzepatide, retatrutide) for weight loss; BPC-157 and TB-500 for recovery; GHK-Cu for skin; ipamorelin and CJC-1295 for growth and lean mass; NAD+ for longevity; and Semax and Selank for focus and mood. Popularity mostly tracks the strength of evidence and the size of the goal — but the right peptide for you depends on your specific goal, not the trend.

| Goal | Popular peptides | At Novapep |
|---|---|---|
| Weight loss | Semaglutide, Tirzepatide, Retatrutide | from €75 → |
| Recovery | BPC-157 + TB-500 | from €75 → |
| Growth / lean mass | Ipamorelin, CJC-1295 | from €36 → |
| Skin | GHK-Cu | from €29 → |
| Longevity | NAD+, Epithalon | from €124 → |
| Focus / mood | Semax, Selank | from €30 → |
Popularity broadly tracks evidence + demand — the GLP-1 class leads because both are high.
Two things drive popularity: how strong the evidence is, and how many people share the goal. The GLP-1 weight-loss peptides top both — large clinical trials plus a near-universal goal — which is why they dominate. BPC-157 and TB-500 are popular because almost everyone deals with injuries and recovery.
The rest cluster around big, common goals: skin (GHK-Cu), lean mass (growth-hormone peptides), longevity (NAD+) and cognition (Semax/Selank). In other words, popularity is mostly a proxy for 'strong evidence meets widespread demand.'
The trap is buying the trendiest peptide instead of the one that fits your goal and your body. A hugely popular fat-loss peptide is irrelevant if your goal is recovery, and the 'best-seller' isn't automatically the safest or most appropriate for your health situation.
Start from your goal and your bloodwork, not the leaderboard. Novapep matches the compound to your medical exams and recommends only what fits — which is how you avoid buying popular but wrong. New here? Start with what peptides are.

The GLP-1 weight-loss peptides — semaglutide, tirzepatide and retatrutide — are the most widely used, driven by strong clinical evidence and a near-universal goal.
Popularity tracks evidence and demand, so popular peptides often are well-supported — but the best one for you depends on your specific goal and health, not the trend.
Not necessarily the most popular one — start from your goal and, ideally, your bloodwork. Match the compound to what you're trying to achieve rather than to a best-seller list.
Because they combine strong clinical-trial evidence for weight loss with a goal that a huge number of people share. High evidence plus high demand equals high popularity.
