How many vials are in a SSR1 kit?

Every kit is 10 vials. The "5mg" label means 5 mg per vial, so a 5 mg kit gives 50 mg total, a 10 mg kit gives 100 mg total, and so on.

Is the price per vial or per kit?

Prices shown are for the full 10-vial kit. We always show the per-vial and per-mg breakdown so you can compare honestly.

What payment methods do you accept?

SEPA bank transfer (IBAN) is our default — secure, fee-free, instant confirmation. We can also send a secure card-payment link on request via WhatsApp.

Do you ship outside the EU?

Yes — UK, USA, Middle East, Asia and Australia. EU is fastest (5–14 days). International is tracked and discreet. Some destinations are restricted — checkout will tell you.

How is purity verified?

Every batch is independently tested by HPLC and mass spectrometry. We can send the batch-specific COA for your order on request.

Is this intended for human use?

No. SSR1 sold by Regena Peptides is a research compound supplied strictly for in-vitro laboratory investigation by qualified professionals. Not for human or veterinary use.

What makes SS-31 different from other peptides?

It targets the mitochondrial inner membrane via cardiolipin binding rather than a plasma-membrane receptor, stabilising electron-transport-chain supercomplexes and reducing ROS leakage.

What is elamipretide?

The clinical-development name for the SS-31 molecule (also MTP-131). Chemically the same tetrapeptide.

What is the reported half-life?

Short in plasma (~2 hours), but preferential mitochondrial accumulation appears to prolong functional effects at the organelle level.

Storage recommendations?

Lyophilised at −20 °C; reconstituted solution refrigerated at 2–8 °C.

Is SS-31 approved for human use?

No — SS-31/elamipretide remains investigational and is supplied strictly as a research reference compound.

What purity level is guaranteed?

HPLC ≥99% with mass-spectrometry confirmation. Batch-specific COAs on request.

Lab-tested ≥99% pure

Sold as 10-vial kits · minimum order

We don't sell single vials. Every order is a sealed 10-vial research kit — it's how serious labs and long-protocol researchers actually buy, and it's how we keep quality and price honest.

✓ Lower €/mg — batching 10 vials cuts our fill cost, and we pass it to you (per-vial price is 40–60% lower than typical single-vial pricing).
✓ One batch, one COA — all 10 vials come from the same lab-tested batch, so results stay consistent from first vial to last.
✓ Lasts 8–12 months — a sealed 10-vial kit keeps for roughly 8–12 months in cold storage, so you're not re-ordering mid-study. Once mixed with bacteriostatic water, a vial lasts about 2 months in the fridge (2–8 °C).
✓ One shipment, one customs pass — fewer parcels = lower risk, lower shipping cost per vial, faster to your bench.

What is SSR1?

SSR1 (elamipretide) is a mitochondria-targeted tetrapeptide that binds cardiolipin in the inner mitochondrial membrane, supporting cristae architecture and electron transport efficiency in research models.

Mechanism of action

Binds cardiolipin to stabilize inner mitochondrial membrane.

Primary research areas

Mitochondrial dysfunction models.

Research notes

Used in studies of cardiac and skeletal muscle mitochondrial dysfunction.

SSR1: expanded research context

SS-31 (elamipretide, MTP-131) is a mitochondria-targeting tetrapeptide that binds selectively to cardiolipin on the inner mitochondrial membrane. Cardiolipin binding stabilises electron-transport-chain supercomplexes and reduces mitochondrial ROS leakage. This mechanism places SS-31 in a different pharmacological class from most other peptide references — it acts at the organelle level rather than through a plasma-membrane receptor.

Clinical development (under the name elamipretide) has included Barth syndrome, primary mitochondrial myopathy, geographic atrophy in age-related macular degeneration, and heart failure. Some programmes have advanced, some have failed key endpoints — a nuanced evidence base that makes SS-31 a valuable reference compound for mitochondrial-bioenergetics research.

Verified
COA matched batch number exactly
Ordered three batches of BPC-157 over four months. Each shipment arrived cold-packed with a COA and the batch numbers cross-checked against the public testing database. Purity reported between 98.7% and 99.2% — consistent with what we measured in-house by HPLC.
Dr. M. AnderssonStockholm, Sweden
Verified
Fast UK delivery, clean reconstitution
Discreet packaging, arrived in 5–14 days to London. Lyophilised cake was firm, dissolved completely in bac water with no cloudiness. Dose math in IU on the calculator made repeat dosing trivial.
J. WhitmoreLondon, UK
Verified
Best documentation I've seen from a supplier
We compared three suppliers as part of a sourcing audit. Regena was the only one with chromatograms, retention times and lab-named COAs published per batch. That's the standard the rest of the industry should meet.
Prof. L. RomanoMilan, Italy
Verified
Good product, customs took an extra day
Product itself is excellent — clean reconstitution, COA available. Customs added 24 hours which is outside Regena's control. Support replied within an hour when I asked for an update.
K. PetersenCopenhagen, Denmark
Verified
Independent lab agreed with stated purity
We sent a sub-sample to an independent lab. Their result was within 0.4% of the published Regena COA. That's a level of transparency you almost never see in research-peptide sourcing.
Dr. S. PatelBirmingham, UK
Verified
Cold chain held the whole way
Temperature indicator strip in the package stayed in the green. Vials still chilled on arrival despite a 3-day route. Whoever packs these boxes knows what they're doing.
A. MüllerBerlin, Germany
