aethelcore.is Review & Prices

Note: Vials seem to ship without labels.

Aethelcore operates as an EU-domestic supplier shipping out of German warehouses (via DHL/UPS). They use a batch-by-batch drop model, commissioning third-party Janoshik tests for purity as well as Janoshik tests for endotoxin levels before listing compounds. While they state a target of 98%+ purity across Janoshik reports, results naturally vary between compounds and production batches.

For instance, checking their public COA library ↗, their 20mg Tirzepatide batch tested at 4.6 EU/vial for endotoxins. While not an outright fail or dangerous level for research compounds, 4.6 EU/vial is noticeably on the higher side compared to cleaner, lower-endotoxin runs.

On the forums, they gained some attention when an October CJC-1295 (no DAC) + Ipamorelin blend came back cloudy and under-dosed at the lab (Janoshik Report #243218 ↗)—they posted the failed lab sheet publicly and seemingly trashed the entire batch rather than shipping it out.

Recent forum feedback on the MESO-Rx thread (page 10) ↗ generally reports quick 24–48h EU deliveries and active Telegram support, but as with any domestic peptide source, users should inspect individual batch COAs directly rather than assuming blanket guarantees.
