Precision peptide formats for controlled professional workflows
Stack One is the first multi-volume setting peptide pen — pre-compounded, dial-volume setting, ready for controlled handling and documentation. No reconstitution. No bacteriostatic water. No syringe math. Now available at wholesale to qualified medspas and clinical practices.
Professional users are asking. Most clinics can't deliver.
Peptide therapy is one of the fastest-growing aesthetic and longevity categories, but most practices still rely on compounded vials and home-mixing — a workflow that's slow at the chair, hard to repeat across staff, and a constant inventory headache. Stack One removes the friction so your professional users receives a standardized, documented format.
One device. Every protocol.
A pharmaceutical-grade multi-dispense pen designed for the clinic. Pre-compounded cartridges, calibrated dial, sealed sterile filling. Hand it to a nurse and the protocol delivers itself.
Pre-compounded cartridges
Peptides arrive sealed inside the cartridge with saline / Class 3 Pure Water — up to one year of stability without any bench prep.
Calibrated dial system
Five dial positions deliver 0.15 – 0.75 mL with repeatable precision. Any tech can dispense at the chair without unit conversions.
Up to 20 Dispense per cartridge
Built for protocols. Sell a starter pen, restock cartridges — recurring revenue without the compounding burden.
Cross-formulation compatibility
One pen body, every Stack One stack. Professional users keep the pen between protocols — recovery, longevity, aesthetic, cognitive.
Engineered for the chair, not the bench.
The Stack One pen is built around a sealed, pre-compounded cartridge and a five-position dial. There is no priming protocol, no math, no exposure to the peptide outside the cartridge. Your tech reads the dial, sets the dispense setting administers — and that's the visit.
The science was never the obstacle. The workflow was.
Compounded peptides put the burden on the practice — reconstitution, storage, labelling, dosing math, contamination risk. Stack One ships you a sealed device that's ready for the patient the moment it leaves the package.

Margin scales with volume.
Tiered partner pricing across all formulations — the more your clinic moves, the better the margin. Pricing is shared after we verify the practice; the structure below shows how the ladder works.
All tiers include COA per batch, training materials, and patient education collateral. Net-30 terms reviewed for Partner and Flagship accounts.
More than a wholesale account.
Partner clinics get the operational support to actually launch peptides as a service line — not just a box of pens.
Co-branded patient education
Take-home brochures, in-treatment one-pagers, and indication-specific patient handouts — co-branded with your practice.
Staff training
Live or recorded clinical onboarding for your nurses and injectors. Dosing, indications, contraindications, talk-tracks.
Marketing assets
Photography, social tiles, treatment-room signage and consult scripts. Plug into your existing channels.
COA library + compliance
Every batch ships with a Janoshik Certificate of Analysis. Full COA library accessible to your clinical team.
Dedicated account rep
One contact for restocks, indication questions, and protocol guidance. Net-30 terms available at Partner tier.
Restock cadence
Automated reorder cadence based on your patient throughput — never run out mid-protocol.
