Research-grade peptides, documented to the milligram.
Ten well-characterised compounds supplied as lyophilised powder, each with lot-level purity and identity data, so your results start from a reference you can trust.
≥99% HPLC purity
Each batch is quantified by reverse-phase HPLC against specification.
Batch-level COA
Lot-specific certificate with HPLC and mass-spectrometry data.
Same-day dispatch
Orders placed before 2 PM ET ship the same business day.
Sealed, labelled vials
Lyophilised powder in sterile-sealed glass with lot-tracked labels.
Ten research compounds
Purity and identity, shown not claimed
Reproducible work starts with a reference material whose composition is documented. Every lot passes the same three-step release process.
Synthesis & lyophilisation
Solid-phase synthesis, purification and freeze-drying into a stable, weighed powder.
HPLC purity + MS identity
Reverse-phase HPLC quantifies purity; mass spectrometry confirms the molecular mass against theory.
COA issued per lot
Results are recorded on a lot-specific certificate of analysis tied to the number on your vial label.

Organised by what you study
From incretin pharmacology to tissue-repair models, each compound is grouped by its main area of published research.
Keep your reference material stable
Lyophilised peptides are robust when stored correctly. These basics apply to every compound we supply.
Cold and dry
Store lyophilised powder at −20 °C. Several weeks at 2–8 °C is acceptable for short-term use.
Away from light
Keep vials in their carton. Light and moisture are the main drivers of long-term degradation.
Limit freeze–thaw
Once reconstituted for in-vitro work, hold at 2–8 °C and avoid repeated freeze–thaw cycles.
Common questions
What does “for research use only” mean?
Our products are laboratory reference materials. They are not drugs, foods, cosmetics or supplements, have not been evaluated by the FDA, and must not be administered to humans or animals. They are intended for in-vitro and other legitimate laboratory research.
How is purity verified?
Purity is quantified by reverse-phase HPLC and identity is confirmed by mass spectrometry. Results are recorded on a lot-specific certificate of analysis (COA).
Will I receive a certificate of analysis?
Lot-specific COAs are available on each product page and on request. Quote the lot number printed on your vial label and we will send the matching report.
How should I store peptides?
Keep lyophilised powder at −20 °C, away from light and moisture. After reconstitution, hold at 2–8 °C and use within a few weeks, avoiding repeated freeze–thaw cycles. Product pages list compound-specific notes.
When will my order ship?
Orders placed before 2 PM ET on a business day ship the same day. Orders over $200 qualify for free shipping.
Who can purchase?
Qualified researchers and licensed laboratories aged 21 or older. By ordering you confirm that you will use materials for legitimate research purposes and in accordance with applicable law.
Need documentation for a specific lot?
Send us the lot number from your vial label and we will return the matching certificate of analysis.
