SS-31 50mg – Research Peptide

SS-31 50mg – Research Peptide

If you are sourcing a ss 31 research peptide 50mg vial for laboratory work, the label is the least useful part of the listing. Two vials marked “50mg” can differ in chemical form, peptide content and documentation. This guide explains what to check so you can compare suppliers on evidence rather than headline claims.

Research use only. SS-31 is supplied for laboratory research and analytical work. It is not a medicine, supplement or food, and it is not for human or veterinary use.

What Is SS-31 (Elamipretide)?

SS-31 is a synthetic tetrapeptide, also called elamipretide, MTP-131 or the Szeto-Schiller peptide. Its sequence is D-Arg-Dmt-Lys-Phe-NH2, where Dmt is 2,6-dimethyl-L-tyrosine. The literature describes it as a mitochondria-targeted peptide that associates with cardiolipin in the inner mitochondrial membrane. That has made it a common reference compound in cell-based studies of mitochondrial function, oxidative stress and bioenergetics.

Because it is a modified peptide, with a D-amino acid, a non-standard residue and an amidated C-terminus, quality control matters more than it does for simple sequences.

Check the Chemical Form First

This is where many listings go wrong. Supplier pages give different formulas and molecular weights for SS-31, and some contradict each other.

• Parent peptide: CAS 736992-21-5, formula C32H49N9O5, molecular weight about 639.8 g/mol.
• Trihydrochloride salt: CAS 2244098-12-0, molecular weight about 749.2 g/mol.
• Other counter-ions: acetate and trifluoroacetate forms exist and change the mass of material in the vial.

Ask which form is supplied and whether “50mg” means net peptide or total salt material. A trustworthy supplier answers this on the COA.

SS-31 50mg Vial Price: What Affects the Cost

Buyers often search for the ss-31 50mg vial price research peptide listings before anything else. Price is a fair filter, but compare like with like. Current UK 10mg listings sit at roughly £24.99 to £32.25, so a 50mg vial should be judged on cost per milligram of net peptide, not on the sticker price alone.

Factors that move the price:

• Purity grade: standard versus additionally purified batches
• Endotoxin testing: some suppliers test for it, many do not
• Documentation: batch COA, SDS and third-party verification
• Packaging and shipping: temperature-managed, tracked delivery costs more than plain post
• Stock reliability: a low price on a sold-out variant tells you nothing

Core Specifications to Look For

A credible ss-31 research peptide 50mg listing should state:

Chromatographic purity is not the same as net peptide content. Counter-ions, residual water and solvents all contribute to the weight in the vial, and good COAs address them.

How to Buy Safely: SS-31 50mg Research Peptide Online

Before you order ss-31 research peptide 50mg online, work through this checklist:

1. Verify the business. Look for a registered company name, company number, UK address and phone support.
2. Open the COA before paying. It should carry a batch number matching your vial. Be wary if COA links or QR codes are broken.
3. Confirm the chemical form and what the vial quantity refers to.
4. Check stock and variants. Confirm 50mg is actually available, not just listed.
5. Read shipping and returns. Tracked, protective packaging matters for peptides.
6. Avoid therapeutic language. Any seller giving dosing advice or health claims is a red flag.

UK Legal and Compliance Notes

In the UK, research chemicals must not be marketed as medicines. Suppliers offering dosing schedules, “benefits” or human-use instructions risk breaching medicines law, and buyers who follow them take on the same exposure. Use material only in appropriate laboratory or institutional settings, keep COAs and purchase records, and check MHRA guidance if you are unsure of a product’s status. This is general information, not legal advice.

Treat unverified “monographs” with caution. Some documents online present SS-31 with clinical claims and dosing tables aimed at healthcare use, and their stated formulas and molecular weights can conflict with primary chemical databases. A research supplier should not rely on them.

Storage and Handling

• Store lyophilised vials as directed on the COA or SDS, generally cold, dry and protected from light
• Do not assume a universal solvent. Follow the batch documentation and your validated method
• Aliquot after reconstitution to avoid repeated freeze-thaw cycles
• Label aliquots with date and batch number

Supplier Comparison at a Glance

Frequently Asked Questions

Is SS-31 the same as elamipretide?
Yes, they are the same molecule under different names. Always check the salt form on the COA.

Why does the 50mg vial not always contain 50mg of peptide?
Salt forms, water and residual solvents add mass. Ask whether the label refers to net peptide or total material.

Can I buy SS-31 for personal use?
No. It is sold strictly for laboratory research and is not approved for human or animal use.

What should arrive with my order?
A labelled vial with batch number, plus access to the batch COA and SDS.

Final Thoughts

Choosing a 50mg SS-31 supplier comes down to documentation, chemical clarity and honest labelling. Price matters, but a cheap vial with no verified batch data costs more when a study has to be repeated.
