Questions
Is P21 a medicine?
No. P21 5 mg is sold as laboratory research material, not as a licensed medicine.
Who packs this?
EVOLV PEPTIDES has packed P21 5 mg in the South of England since 2018. The lot number is marked on every vial. Contact hello@evolvpeptides.co.uk.
What does HPLC ≥99% mean here?
HPLC ≥99% is a batch-release specification: the lot was checked against that threshold before packing. It is not independent clinical proof, not a sterility certificate, and not a licence for human use.
Is a paper COA in the box?
Every listed batch has a certificate of analysis. Email the order id or the lot on the vial to hello@evolvpeptides.co.uk and the file for that batch is sent. A paper certificate is not in the carton.
When does it ship?
Packed in the South of England. Next working day across the UK from the South of England when ordered before 14:00 on weekdays, payment cleared. Highlands, islands and Northern Ireland can add a working day. Free UK tracked shipping on orders over £20. Plain outer carton. No compound name on the outside.
Is this powder or pre-mixed?
P21 5 mg is lyophilised powder. EVOLV ships lyophilised peptide as powder in a sealed vial. Bacteriostatic water, when listed, is a separate laboratory solvent SKU — not included in the peptide carton and not a human reconstitution kit.
