Why researchers choose us.

Precision, purity, and proof — the standards serious research is built on.

Only genuine at powerfullypeptides.com — beware imitations.

Where do you ship from?
From inside the EU single market. Dispatched the same working day when payment clears before 2:00 PM Irish time; otherwise the next working day. See shipping times and destinations.
How is quality verified?
Specified to a ≥99% purity target. Independent sample reports are published for GLP-3-RT, GHK-Cu, BPC-157 and TB-500. Results describe the sample tested, not every vial or an untested blend. Products without a published report are not independently verified by us. See the certificates of analysis for reports and laboratory verification links.
What purity can I expect?
Specified to a ≥99% purity target. Read our sourcing and testing information and supplier verification checklist before comparing suppliers.
How is it packaged?
Secure, discreet packaging, fully tracked — reship or refund if a parcel is lost.
What are these products for?
For laboratory research only, not for human or animal consumption. See our research-use policy.
Where can I find research tools and guides?
Use the peptide reconstitution calculator for concentration calculations and browse our research guides for compound-specific evidence. The calculator does not recommend a dose.
