Featured Product
A triple-agonist research compound supplied in a dual cartridge pen format. The lyophilised peptide stays dry and separated from the liquid component until the cartridge is activated in the device — no pre-mixed solution sitting in transit.
Mixed in the pen, not in a warehouse
Powder and bacteriostatic water stay in separate chambers until the cartridge is activated in the device.
≥98% HPLC, COA per batch
Third-party verified purity with a batch certificate available for every cartridge supplied.
Complete kit
Compatible pen, one 40mg dual cartridge and the liquid component contained in the cartridge system.
Position
We don't sell hype. We supply verified compounds — organised by pathway, traceable to the lot, accountable to the literature.

The Standard
Every Proteus® compound is held against the same protocol — from synthesis through to the sealed pouch on your bench. You don't have to take our word for it: the COA is in the box, and the QR code resolves to the live lab record.
GMP-aligned manufacture in audited facilities. Solid-phase peptide synthesis, validated against reference standard.
Reverse-phase HPLC and mass spectrometry on every lot. Purity floor of 98%. Failed lots are destroyed.
Independent third-party Certificate of Analysis. Scan the QR code on the pouch — match the lot, not the label.
Lyophilised, sealed, and dispatched discreetly from the UK. Temperature-stable in transit. 24h tracked delivery.
How it ships
Every Proteus® order ships as a complete research kit. No sourcing bacteriostatic water separately. No loose vials rattling in a box. Your kit arrives in a sealed, tamper-evident matte sachet — inside, a protective twin clamshell case holds your peptide vial alongside a matched 3ml BAC water vial, ready for immediate reconstitution.
Packaging · 01
Precision-moulded medical-grade polymer. Two fitted wells keep your peptide and BAC water vial locked side-by-side — no movement in transit, no risk of breakage. The case stays with the kit through its full research lifecycle.
Packaging · 02
Every order arrives like this: a sealed matte pouch containing your peptide vial, a matched 3ml bacteriostatic water vial, and the twin protective clamshell case. Nothing to source separately — open the pouch and you're ready to reconstitute.

Accessory
portable peptide fridge
Reconstituted peptides demand cold storage. The Proteus® Cold Vault holds your full research stack at a steady 2–8°C — at home, in the lab, or on the move.

Editorial
The peptide market is crowded — and not every seller knows where their products actually come from. Here is why we do things differently, and why our pricing reflects it.
A step-by-step laboratory guide to reconstituting lyophilised research peptides with bacteriostatic water, cold-chain storage, and temperature stability for UK-based research workflows.
A dual-chamber pen keeps the lyophilised powder and its diluent separate until the moment of use. Here is what the chemistry and the pharmacopoeial record actually say about that, versus buying a solution someone else already mixed.
A 15-amino-acid pentadecapeptide derived from human gastric juice. Two decades of preclinical literature on tissue repair — and zero completed Phase 2 or Phase 3 human trials.
What the published literature actually reports on BPC-157 adverse effects, toxicity windows, drug interactions and the open safety questions that remain in human use.
A synthetic fragment of the actin-regulating protein Thymosin Beta-4. Banned in sport since 2011 — and never licensed by any regulator.
The two most-studied repair peptides combined. Synergy is widely claimed in forums — and entirely uncharacterised in controlled trials.
A naturally occurring copper-binding tripeptide that declines with age. One of the most-published peptides in dermatology research.
Central to mitochondrial function and sirtuin signalling. Its decline with age is well-documented; whether restoring it extends human healthspan is not.
Encoded inside the mitochondrial genome itself — a regulator of metabolic homeostasis with growing animal data and almost no human trials.
A synthetic tetrapeptide derived from pineal extract. Russian gerontology has studied it for 40 years — Western RCTs are essentially absent.
GLP-1, GIP and glucagon receptor activity in a single molecule. Phase 2 trial data show the largest weight reductions ever recorded for a metabolic peptide.
The most-prescribed metabolic peptide of the decade. Approved clinically — but research-grade material exists in an entirely separate regulatory category.
The first-in-class dual incretin agonist. SURPASS and SURMOUNT trials redefined what's possible for metabolic peptides.
A small molecule rather than a peptide. Targets the enzyme implicated in adipocyte fat storage.
A Russian-developed analogue of the immunopeptide tuftsin. Anxiolytic effect without sedation in animal models.
A neuroprotective heptapeptide registered in Russia for stroke recovery. Western neurology literature remains thin.
Engineered to retain the fat-burning activity of growth hormone without its IGF-1-mediated growth effects.
The only GHRH analogue with FDA approval — for HIV-associated lipodystrophy. Outside that indication, evidence is more limited.
The 'cleanest' GH secretagogue — minimal impact on cortisol or prolactin compared with earlier GHRPs.
The shortest GHRH fragment that retains biological activity. Once FDA-approved for paediatric GH deficiency; later withdrawn for commercial reasons.
One of the most potent GH secretagogues described — also among the most prone to off-target prolactin and cortisol effects.
A short-pulse GHRH analogue frequently paired with a GHRP to mirror physiological GH release.
The most-researched GHRH + GHRP pairing. Combines a clean GH pulse with selective receptor agonism.
The C-terminal lipolytic tail of human growth hormone — fat-metabolism activity without IGF-1 effects.
A central melanocortin agonist with full FDA approval for female sexual dysfunction. Marketed widely for off-label use in men.
Activates MC1R through MC5R. Marketed for tanning but with a long-known and well-characterised side-effect profile.
Upstream of GnRH — the master switch for the HPG axis. Active human research, both endocrine and emotional.
A 28-amino-acid thymic peptide approved in over 35 countries for hepatitis B/C and as an adjunctive cancer therapy — but not in the UK or US.
Verified Research Reviews
I've been ordering from Proteus for about four months now. The vials arrive properly sealed every time, the lyophilised cake looks textbook, and the reconstituted solution is always crystal clear. Not a single dud vial across three orders.

Ran the batch through our own HPLC as a sanity check — the certificate figures were within 0.2% of what we measured. That's the level of accuracy you'd expect from a pharma supplier, not a research peptide vendor. Genuinely impressed.

Came in a proper twin-vial case with labelled bacteriostatic water and a printed insert. No cheap bubble mailer with a loose vial rolling around. You can tell they actually care about how it arrives.
