Research Monitoring

What changed
in the evidence.

Evidence is not static, and neither are our grades. This is the public log of what moved — new trials, regulatory actions, and every time we changed a compound's grade, with the source that prompted it.

July 2026

EditorialJuly 11, 2026

Synptide launches the compound directory and evidence-grading system

We published canonical, outcome-graded profiles for the first 25 compounds, plus a public A–U evidence framework and this change log.

Evidence-grade changeJuly 8, 2026

Semaglutide graded A for cardiovascular risk reduction on SELECT evidence

We set semaglutide's cardiovascular-outcome grade to A after the SELECT trial's 20% reduction in major cardiovascular events in people with obesity but without diabetes.

Cardiovascular risk reduction: B → A (Established)Semaglutide

June 2026

Label changeJune 20, 2026

Tirzepatide profile updated for obstructive sleep apnea approval

We added obstructive sleep apnea as an A-graded, FDA-approved indication for tirzepatide following the SURMOUNT-OSA trials.

Tirzepatide

May 2026

RegulatoryMay 15, 2026

BPC-157 regulatory note updated for FDA compounding restrictions

We clarified BPC-157's status after the FDA placed it in the category that restricts compounding-pharmacy use, reinforcing its research-chemical grade.

BPC-157
