FAQ

What makes a reusable peptide pen more accurate than a standard syringe for small volumes?
The click-dial mechanism advances the plunger in fixed increments, giving consistent volume delivery across draws. A hand-pulled syringe at small volumes depends entirely on researcher technique and varies more.
Can dilute acetic acid be used as a diluent in a glass peptide pen cartridge?
Yes. Type 1 borosilicate glass cartridges are chemically compatible with dilute acetic acid solutions. Metal pen bodies handle it fine; most plastic pen bodies are not and can crack or cloud with repeated exposure.
How do you account for dead volume in a reusable peptide pen?
Prime one to two clicks into a waste receptacle at the start of each session and after every cartridge change. This fills the adapter and cartridge tip so subsequent clicks deliver actual solution rather than air.
Do you sell replacement dial springs for the peptide pen?
No — we don't sell dial springs, plunger rods, dose windows, or cartridge holders as separate parts. Our reconstitution pens ship as complete, sealed units, and the only user-replaceable part is the 3 ml glass cartridge , which you simply reorder as needed. If a dial stops clicking or advancing, that's the internal mechanism rather than anything serviceable in the field. Contact us with your order number and we'll tell you what we can do. Pens that arrive faulty or were damaged in transit are replaced or refunded at no cost if you reach out within 7 days of delivery with photos.
