Absolutely not. Every product sold on Epic Peptides Lab.net is strictly for research purposes only and is not intended for human consumption under any circumstances. If any product is intentionally or accidentally ingested, contact a healthcare provider immediately. Any customer who indicates intent to consume our research peptides will have their order canceled and their account permanently suspended. Epic Peptides Lab will not discuss potential effects of ingestion — doing so would be unlawful.

No. Epic Peptides Lab will not misrepresent any information on customs documentation. It is the buyer’s responsibility to understand taxes, duties, or VAT associated with importing research peptides into their country.
Every lot is analysed by HPLC for purity and confirmed by mass spectrometry for molecular identity. Results are recorded on a lot-specific Certificate of Analysis, which is available with your order and in our COA library. If a delivered lot does not conform to the specification stated on its Certificate of Analysis, contact us within the period set out in our Return Policy.
All of our research peptides and liquid research chemicals are proudly manufactured in the United States. Epic Peptides Lab is committed to American-made quality, ensuring every product meets the highest standards of purity, potency, and scientific integrity.
For health and safety reasons, we do not accept returns or issue refunds on research peptide products. However, we stand behind our 99%+ purity guarantee — if any product does not meet this standard, we replace it at no cost.
No. All products ship with proper labeling including product name, potency, lot number, expiration date, and warnings. However, we offer white-label options — custom labels with your company’s logo or generic labels without branding. This service is included with wholesale research peptide orders. Contact us within 24 hours of placing your order to coordinate labeling. Orders not updated within 24 hours ship with standard Epic Peptides Lab labels.
All lyophilized research peptides are stable at room temperature for approximately two years in sealed vials. Once reconstituted with bacteriostatic water, store in the refrigerator to maintain potency. For long-term storage of unreconstituted peptides, −20°C or −80°C is ideal.
Lyophilized material is stable at ambient temperature in transit. On receipt, store lyophilized peptides at −20°C, desiccated and protected from light. Solutions should be stored at 2–8°C. Lot-specific storage conditions and shelf life are stated on the Certificate of Analysis and Safety Data Sheet supplied with each product.
Lyophilized is the scientific term for freeze-dried. It describes the state in which our research peptides are shipped and stored. Lyophilized peptides remain stable at room temperature for approximately two years and do not require refrigeration until reconstituted. This method preserves molecular integrity, purity, and potency throughout storage and transit.
No — this is perfectly normal. Some research peptides take a few moments to fully dissolve after reconstitution with bacteriostatic water. Gently roll the vial between your fingers to help. Never shake the vial, as this may damage the peptide’s molecular structure.
Like all of our lyophilized research peptides, Melanotan 2 is stable at room temperature for approximately two years. Once reconstituted with bacteriostatic water, store in the refrigerator. For long-term storage, keep unreconstituted vials at −20°C or −80°C.
Yes, this is normal for certain liquid research chemicals. Vigorously shake the bottle before each use in your research experiments to ensure proper mixing and uniform concentration.
Epic Peptides Lab maintains strategic partnerships with specialized laboratories to produce the highest-purity research peptides available. Our peptides are synthesized using solid-phase peptide synthesis (SPPS) based on Fmoc or t-Boc chemistry to protect the alpha amino group during assembly. The process builds peptide chains from the C-terminus to the N-terminus — the reverse of natural protein synthesis. A deprotection agent removes the protective group, preparing it for coupling with the next amino acid via peptide bond formation. This cycle repeats until the full target sequence is assembled. Once complete, the peptide is cleaved from the resin, deprotected, precipitated, washed, and lyophilized into freeze-dried powder. Every batch undergoes HPLC purification and mass spectrometry analysis to confirm molecular identity, sequence accuracy, and purity.
Every research peptide undergoes rigorous quality verification:
– HPLC Purification & Analysis — Peptides are purified using reverse-phase chromatography, identifying by-products present.
– Mass Spectrometry Verification — Molecular mass is confirmed to validate the correct target sequence.
– Net Peptide Content Analysis — Amino acid evaluation confirms composition and identity.
– Certificates of Analysis — Complimentary HPLC and MS results provided with most orders. Any peptide not meeting our 99%+ purity standards is discarded. All products are considered the confidential property of the purchaser.
Peptide purity is the percentage of the target sequence present among total peptide material, measured by HPLC at 214 nm. During synthesis, some chains may be incomplete or contain errors. Epic Peptides Lab purifies all research peptides using reverse-phase HPLC and verifies with mass spectrometry to achieve 99%+ purity — meaning 99% or more of the material is the exact compound you ordered. Guaranteed.
Net peptide content is the percentage of actual peptide material relative to total product weight, which includes non-peptide components like water, salts, solvents, and counter ions. It typically ranges from 70–85%. Peptide purity measures the target sequence among all peptide material, while net peptide content measures peptide weight among total weight. Account for net peptide content when calculating concentrations for research experiments.
Solubility depends on the peptide’s polarity and amino acid composition:
Step 1: Determine Charge
– Assign +1 to basic residues: Arg (R), Lys (K), His (H), N-terminal amine
– Assign −1 to acidic residues: Asp (D), Glu (E), C-terminal carboxyl
Step 2: Choose Solvent
Basic peptides (positive charge): Try sterile distilled water first. If unsuccessful, try 10–25% acetic acid, then TFA (10–50 µl).
Acidic peptides (negative charge): Try PBS (pH 7.4). If unsuccessful, add 0.1 M ammonium bicarbonate. Cysteine-containing peptides require de-gassed acidic buffers.
Neutral peptides (zero charge): Try acetonitrile, methanol, or isopropanol. For hydrophobic peptides, use DMSO then dilute with water. For Cys-containing peptides, use DMF instead.
Tips: Test a small portion first. Never shake vials. Store reconstituted peptides refrigerated. Avoid freeze-thaw cycles. Keep lyophilized peptides at −20°C or −80°C long-term.
APIs (Active Pharmaceutical Ingredients) are biologically active substances in pharmaceutical drugs. Since Epic Peptides Lab products are sold strictly for research and development purposes, our liquid research chemicals are not classified as APIs — their intended use as research materials places them in a different regulatory classification.
In solid-phase peptide synthesis, a resin is the polymeric backbone to which amino acid substrates attach during synthesis. Linkers are intermediate structures connecting the resin to the substrate, controlling which functional groups are exposed. The resin-linker combination directly impacts synthesis efficiency and peptide quality.
Yes. We provide custom peptide synthesis for researchers requiring specific sequences, modifications, or formulations. Contact our team with your requirements and we will respond within 48 hours with a detailed answer and quote. Visit our Custom Peptide Synthesis Page for more information.
Extensive scientific literature is available online for the research peptides in our catalog. Epic Peptides Lab does not comment on alleged uses or administration methods. By purchasing from Epic Peptides Lab, you confirm you are qualified to handle research peptide compounds and will not ingest any products.
