Comparison Centre

Two compounds, the same questions, no cherry-picking

Marketing compares compounds on whichever measure flatters them. This compares them on the same fields every time — including the awkward ones like how much human safety data exists. Every score here rates the evidence, not the compound: a higher number means stronger or more mature research, not that something is safer or works better.

Sharing keeps the two compounds you picked.

How to read these scores

Every number here rates the evidence, not the compound. They are editorial 0-100 strength ratings, not percentages, and not a rating out of five stars.

  • Human efficacy evidence strength — Higher = more and better-quality human evidence. It does not mean the effect is bigger or that the compound works for you.
  • Preclinical evidence strength — Higher = more animal, tissue or cell research. Preclinical results are a starting point, not proof of a human benefit.
  • Human safety evidence strength — Higher = more mature, better-documented human safety data. It does not mean the compound is safer than one with a lower number. A score of 80 does not mean “80% safe”.
  • Evidence level (L0-L5) — the strongest type of study behind the compound, from anecdote (L0) to large replicated human trials (L5). It is a description of the study evidence, not a quality, safety or recommendation rating.
  • Confidence — how likely we think it is that this rating changes as new research lands. Low confidence means the picture is unsettled, not that the compound is bad.

None of these ratings is medical advice, a safety guarantee, or a recommendation to use anything. How we grade evidence.

DSIP / Emideltide

A neuropeptide named for a sleep effect first described in the 1970s that decades of follow-up have never clearly replicated in humans.

How far human research has progressed

DSIP / Emideltide

Historical small studies with inconsistent results

Semax

Registered in one national market; limited Western-quality controlled evidence

Claim-specific benefit evidence

A human exposure study or trial registration does not establish that the claimed benefit occurs.

Human efficacy evidence strength

Higher = more and better-quality human evidence. It does not mean the effect is bigger or that the compound works for you.

Preclinical (animal / lab) evidence strength

Higher = more animal, tissue or cell research. Preclinical results are a starting point, not proof of a human benefit.

Regulatory status (legal position, not proof it works)

DSIP / Emideltide

Check jurisdiction-specific details in the profile.

Not an approved medicine in any major region. FDA has identified it as a bulk substance presenting significant safety risks for compounding; that listing status changed during 2026, and DSIP (emideltide) was covered by FDA's Pharmacy Compounding Advisory Committee meeting on 23-24 July 2026 across insomnia, opioid-withdrawal and narcolepsy-related nominations.

Semax

Check jurisdiction-specific details in the profile.

Not approved by the FDA or other major Western regulators. FDA material notes Semax is registered in Russia as nasal drops, while intranasal and injectable products marketed in the US are not FDA-approved. FDA has identified it as a bulk substance presenting significant safety risks for compounding — a compounding safety classification, not an 'FDA ban' — and it was covered by FDA's Pharmacy Compounding Advisory Committee meeting on 23-24 July 2026.

Common claims

Cancer-related questions raised by the biology

These are theoretical or monitored questions raised by how a compound works. They are not evidence that it causes cancer.

DSIP / Emideltide

No established human cancer signal; systematically unstudied.

Semax

No established human cancer signal and no systematic data either way. The honest position is unstudied.

What this adds up to, in plain English

DSIP / Emideltide

This sits in theory and anecdote. Popular claims about it should be treated with very low confidence.

Semax

The interesting work is in animals and lab studies. Treating it as an established human treatment is not supported by evidence.

A comparison is not a recommendation

Neither column here is an endorsement, and the compound with the higher numbers is not the “better” or “safer” one — it is simply the one with more or better-quality research behind it. Two compounds can both be poorly evidenced, and better-evidenced says nothing about whether either is a sensible idea for a specific person. That is a conversation for a qualified clinician.
