Tested by someone who isn’t us
Every batch goes to an independent lab before it ships. Identity (is it exactly the peptide on the label), purity (how clean it is) and potency (is the amount in the pen the amount on the label). We don’t grade our own homework.
The ≥99% standard
Our purity standard is ≥99% by HPLC — the same method pharmaceutical labs use — with identity confirmed by mass spectrometry. That’s the number people mean when they say “pharma-grade”. If a batch doesn’t hit it, it doesn’t become a pen.
Pre-filled means precise
Because your peptide is mixed and filled at the right concentration before it reaches you, potency isn’t up to your kitchen counter. Dial 250 and you get 250. The Smart Pen and the Human 2.0 app keep every dose on the record.
Get the report for your pen
Product pages link the lab report when it’s published. Want the one for the batch in your hand? Send us the batch number on your pen and we’ll email it. We’d rather you check than wonder — and our guide on reading a lab report walks you through every line.
Cold-chain, discreet, on time
Pens ship refrigerated in plain packaging with tracking texted to you. Something not right when it arrives? Message the team with your order number and we fix it fast.
