What is PT-141?
PT-141 is a synthetic peptide. Its other name is Bremelanotide. Researchers use it in lab studies only. So, this product is for research purposes, not human use. At zenpeptideamanda.com, every batch ships with a Certificate of Analysis (COA).
Does Janoshik test PT-141?
Also, every batch from zenpeptideamanda.com gets tested by Janoshik Laboratory. This is an independent lab. They check purity, identity, and mass. So, you get real data, not guesses. Also, the COA is posted with each batch. Therefore, you can verify the lot yourself before you order.
What purity level does it have?
This PT-141 comes in at 99.2% purity, confirmed by Janoshik. That’s the main selling point here. High purity means fewer unknowns in your research setup. But purity alone isn’t enough. You also need correct storage and handling. We cover that below.
What form does it come in?
Again, PT-141 ships as a lyophilized powder. This is a freeze-dried form. It’s the standard for peptide stability. Lyophilized powder holds up better during shipping than liquid form. Next, you’ll need to reconstitute it properly before any lab use.
How do I store PT-141?
Store the lyophilized powder at -20°C. Keep it in a dark place. Avoid light and moisture exposure. Once reconstituted, refrigerate at 2-8°C. Use within the recommended window for your protocol. Finally, always label vials with date and lot number for tracking.

FAQ
Is PT-141 the same as Bremelanotide?
Yes. PT-141 and Bremelanotide refer to the same peptide compound.
What is the molecular weight of PT-141?
The molecular weight of PT-141 is approximately 1025.2 g/mol.
How should PT-141 be reconstituted?
Researchers typically reconstitute lyophilized peptides using sterile water or bacteriostatic water. Always follow your lab’s standard protocol.
Does PT-141 need a COA?
A COA confirms purity and identity for each batch. At zenpeptideamanda.com, every PT-141 order includes one from Janoshik.
How long does lyophilized PT-141 last?
Lyophilized powder, stored at -20°C and protected from light, generally maintains stability for extended periods. Reconstituted solutions have a shorter window and should be refrigerated.
Where can I see the lab results for PT-141?
COA results from Janoshik are available with each batch on zenpeptideamanda.com. Check the lot number on your vial against the posted COA.
