Pricier than the bulk suppliers. The COA, packaging, and lot traceability justify it for our research record-keeping, but it's a notable line on the budget. Easy 5 stars on quality, 4 on value.

Every lot ships with both HPLC and mass-spec confirmation. The MS trace caught a sub-1% impurity that the discount supplier we used previously had silently included for months. Worth the premium just for that.

Cross-country shipment of IGF-1 LR3 arrived intact, lot label perfectly preserved, desiccant pack dry, tamper-evident seal undisturbed. That alone justifies the premium over the discount suppliers I've burned on.
