SS-31 (Elamipretide) 20mg Research Pen
Pre-Filled Multi-Dose Dial-a-Dose Pen System • 12x Micro-Needles Included • Zero Reconstitution Required
The SS-31 20mg Research Pen provides pharmaceutical-grade Elamipretide (CAS: 736992-21-5, MW: 639.80 g/mol) in an all-in-one pre-filled 3mL cartridge delivery device. Designed for in vitro mitochondrial studies, SS-31 directly binds cardiolipin in the inner mitochondrial membrane (IMM) to optimize cristae architecture, protect respiratory supercomplexes, and restore ATP synthesis. Calibrated dial clicks (4 clicks = 250mcg) eliminate manual reconstitution errors.

Engineered for Precision Research Outcomes
Generic vendors ship peptide vials with vague purity claims and no verifiable lot history. We operate under strict clinical laboratory analytical oversight.
≥99.0% HPLC & MS Verified
Every production batch undergoes High-Performance Liquid Chromatography (HPLC) and Mass Spectrometry testing to verify molecular weight (639.80 g/mol) and identity.
100% UK Stock & Dispatch
All vials stocked locally in our UK laboratory facility. Orders placed before 3:00 PM GMT ship same business day in plain, discreet, climate-regulated packaging.
Cleanroom Nitrogen Flushed
Sealed under high-purity inert nitrogen with sterile bromobutyl stoppers and tamper-evident flip-off aluminum seals to prevent moisture oxidation and peptide degradation.
Batch COA on Every Vial
Each vial label features a serialized lot number and QR code linking directly to the corresponding laboratory analytical Certificate of Analysis and purity chromatogram.
SS-31 Pen Click Guide & Dose Conversion
Turn the dial to your exact research dose. Pre-filled 20mg solution eliminates all reconstitution calculations, mixing needles, and bacteriostatic water.

Turn the click selector clockwise until your target dose appears in the indicator window.

The Science Behind SS-31 (Elamipretide)
Grounded in published PubMed Central literature, ScienceDirect peer reviews, and Phase II/III human clinical trial registries.
Investigator Study Summaries
SS-31, a Mitochondria-Targeting Peptide, Ameliorates Kidney Disease
Comprehensive review detailing the pharmacokinetics and molecular mechanisms of SS-31 (Elamipretide). Demonstrates that SS-31 selectively concentrates in the inner mitochondrial membrane (IMM) to protect renal cellular bioenergetics and prevent organ injury.
Proves that SS-31 does not merely act as an external antioxidant scavenger; it structurally repairs inner membrane lipid scaffolds to rescue energy production under ischemic and diabetic stress.

Repair & Prepare
Stabilizes damaged mitochondrial membranes, reduces oxidative stress and inflammation, and anchors cardiolipin microdomains.
Boost Production
Activates AMPK pathways, enhances mitochondrial biogenesis, and boosts energy metabolism once structural cristae are repaired.
Optimal Performance
Increased ATP yield, enhanced cellular resilience, and long-term mitochondrial integrity under metabolic stress.
Cardiolipin Affinity & IMM Binding
SS-31 selectively concentrates on the inner mitochondrial membrane (IMM) to electrostatically bind cardiolipin, preventing lipid peroxidation and cristae collapse.
ATP Synthase & ETC Stabilization
By stabilizing cardiolipin-protein microdomains, SS-31 optimizes electron transfer between Complexes I, III, and IV, enhancing oxidative phosphorylation and cellular ATP yield.
ROS Mitigation Without Scavenging
Inhibits reactive oxygen species (ROS) at their site of origin by preventing electron leakage rather than merely neutralizing downstream free radicals.
mPTP Inhibition & Cristae Integrity
Preserves cristae architecture and prevents premature opening of the mitochondrial permeability transition pore (mPTP), preventing pro-apoptotic cytochrome c release.

SS-31 20mg Pen vs. Raw Powder Vials (Proforma Peptides)
Why leading UK laboratories have upgraded from messy raw powder reconstitution to our pre-filled dial pen delivery system.
| Feature / Standard | SS-31 20mg Pen (Our Lab) | Generic Vials (e.g. Proforma) |
|---|---|---|
| Format & Preparation | Turnkey Pre-Filled 20mg Dial Pen (Ready to Use in 5 Seconds) | Loose lyophilised powder requiring separate BAC water, syringes & mixing |
| Dosing Accuracy & Calibration | Audible Calibrated Dial Clicks (4 Clicks = 250µg, 8 Clicks = 500µg) | Manual syringe drawing with high meniscus reading errors |
| Included Accessories | 12x Sterile Disposable Micro-Needles (31G) Included in the Box | No needles or syringes included (must be sourced separately) |
| Cartridge Protection & Shelf Life | Airless Borosilicate Cartridge (Prevents bacterial contamination) | Standard vial with repeated rubber stopper needle punctures |
| HPLC Batch Testing Standards | 100% Every-Batch HPLC & Mass Spec Testing (Lot #B8: 99.42%) | HPLC analysis 'on select batches only' (no live chromatogram) |
| UK Delivery Speed & Tracking | Royal Mail Tracked 24 (Same-day dispatch before 3:00 PM GMT) | Standard post with 1–2 business day processing delay |
SS-31 Analytical Specifications & HPLC
Every batch undergoes reverse-phase high performance liquid chromatography (RP-HPLC) and electrospray ionization mass spectrometry (ESI-MS).
