Frequently Asked Questions

Prescribed Vials is a research-focused peptide education and sourcing guide. We aggregate peer-reviewed data on peptide mechanisms, purity standards, and proper handling protocols to help researchers make informed sourcing decisions.

We cover the most researched peptide categories: tissue-repair peptides (BPC-157, TB-500), copper peptides (GHK-Cu), growth hormone secretagogues (CJC-1295, Ipamorelin, Tesamorelin), longevity peptides (Epitalon, NAD+), metabolic peptides (MOTS-c, AOD-9604), and multi-peptide blends (Wolverine Blend, Glow Blend).

Research-grade peptides should have minimum 98% purity verified by HPLC analysis, with molecular identity confirmed by mass spectrometry. Always request batch-specific Certificates of Analysis (COAs) from independent third-party laboratories. Avoid suppliers who cannot provide current COAs.

Store lyophilized peptides at -20C protected from light and moisture. Reconstituted solutions should be refrigerated at 2-8C and used within 14-21 days. Use bacteriostatic water for reconstitution. Never refreeze reconstituted solutions.

A valid COA should include: the peptide name and batch number, HPLC purity percentage (98%+ target), mass spectrometry confirmation of molecular weight, endotoxin testing results, the laboratory name and accreditation, and the date of analysis. Third-party COAs are more reliable than manufacturer self-testing.

Research-grade peptides (RUO - Research Use Only) are synthesized for laboratory investigation and are not manufactured under pharmaceutical GMP conditions. Pharmaceutical-grade peptides undergo FDA-regulated manufacturing. All peptides on this site are designated for research purposes only.

No. All peptides featured on Prescribed Vials are designated Research Use Only (RUO). They are not approved by the FDA for human consumption, veterinary use, or any therapeutic purpose. All content describes preclinical laboratory studies, not clinical recommendations.

Research-grade peptides with 98%+ purity, HPLC verification, and third-party COAs are available at researchvials.com. All peptides ship from the USA with cold-chain packaging to maintain product integrity. This site is an educational resource and does not sell products directly.

Research peptides are short chains of amino acids — typically between 2 and 50 residues — synthesized for laboratory investigation. They let researchers study receptor binding kinetics, cellular signaling cascades, and enzyme interactions with high specificity. They are not intended for human use.

It means HPLC analysis confirmed that at least 98% of the lyophilized powder is your target peptide. The remaining fraction is typically truncated sequences or deletion peptides from synthesis. This matters because impurities can activate off-target pathways and wreck dose-response curves. Mass spectrometry provides the second check, confirming molecular identity.

Keep lyophilized (freeze-dried) vials at -20°C. They are remarkably stable in this form — 12 to 24 months with no significant degradation. Once you reconstitute with bacteriostatic water, move to 2-8°C and use within 30 days. The cardinal rules: no repeated freeze-thaw cycles, protect from light, sterile technique every time you draw from the vial.

It means a lab with zero financial ties to the manufacturer independently verifies identity, purity, and endotoxin levels. This eliminates the obvious conflict of interest in self-testing. The resulting Certificate of Analysis (COA) gives you hard data about what is actually in the vial — not what someone claims is in it.

Swab the vial stopper with an alcohol wipe. Draw your bacteriostatic water into a sterile syringe. Inject slowly down the inside glass wall of the vial — not directly onto the cake of powder, which can denature it. Let it sit for a minute, then gently swirl. Never shake. The solution should be perfectly clear. If it is cloudy, something went wrong.

It means the product exists solely for laboratory research — in vitro cell culture work, preclinical animal studies, and educational purposes. RUO compounds have not gone through FDA approval for human safety or efficacy. They cannot legally be sold as drugs, supplements, food additives, or for veterinary use.

Look for four things. First, HPLC purity — should be 98%+ with a clean chromatogram showing one dominant peak. Second, mass spectrometry — the observed molecular weight should match the theoretical weight within instrument precision. Third, appearance — should state white or off-white lyophilized powder. Fourth, endotoxin testing — should be below detection limits for injectable-grade material.

PubMed (pubmed.ncbi.nlm.nih.gov) is the gold standard. Search by peptide name, CAS number, or mechanism. Start with review articles — they synthesize the field so you do not have to read 50 primary papers first. Every PMID we cite on this site links directly to the PubMed entry so you can verify our claims.
