Per-Lot Testing
Tested Lot by Lot
Not a representative report for a similar batch — the certificate you scan belongs to the exact lot in your hand.
Our Quality Commitment
From synthesis through to shipment, every step is set up to put a characterised, documented peptide in your hands.
The Tomorrow Difference
Most of this category asks for trust. We'd rather hand you the paperwork and let you check.
Documented Process
Controlled Synthesis Process
Our peptides are produced under documented quality procedures, with solid-phase synthesis and HPLC purification carried out to a written protocol batch after batch.
Independent Labs
Third-Party Identity Testing
Identity and content are confirmed by an independent analytical laboratory with no stake in the result. Full Certificates of Analysis are published, not summarised.
99%+ Purity
99%+ Purity Standard
A lot that doesn't clear our purity threshold doesn't get listed. That is the whole quality gate — there is no second tier.
Our Quality Process
Six controlled steps between raw material and the vial that reaches you.
-
01
Raw Material Verification
Amino acid purity, solvent grade and reagent specification are all verified before synthesis begins.
-
02
Peptide Synthesis
Solid-phase peptide synthesis (SPPS) under controlled cleanroom conditions, each run following a validated protocol.
-
03
Purification
Reverse-phase HPLC strips residual impurities up to the target purity, with repeat passes where a batch needs them.
-
04
Identity & Content Testing
HPLC content analysis and mass-spectrometry identity confirmation on every batch.
-
05
Documentation
A full Certificate of Analysis is issued against the lot number, and batch records are kept for traceability.
-
06
Packaging & Storage
Lyophilized peptides are sealed under nitrogen and held in climate-controlled storage until dispatch.
Our Commitments to You
Documented Production
Every batch is produced to written quality and documentation standards, not to whatever the run happened to yield.
Lot Traceability
Every vial traces to its lot, and every lot traces to the report that released it.
Publish The Misses Too
If a batch is pulled after release, the lot page says so. A certificate that only ever shows good news isn't worth reading.
Answer The Awkward Ones
Ask us where something came from or why a number looks the way it does, and you'll get a straight answer or an honest "we don't know yet".
See It On A Real Lot
Every order ships with the Certificate of Analysis for its own batch.
Every lot we ship, with the paperwork to back it up — lot by lot.
