Storage & reconstitution
01 — Lyophilized storage
Store lyophilized vials at −20°C (or colder) in a dry, dark environment. Avoid repeated temperature cycling before reconstitution.
02 — Reconstitution
Reconstitute with bacteriostatic water (0.9% benzyl alcohol). Introduce the diluent slowly along the vial wall; gently swirl — do not shake vigorously. Typical research volumes: 1–2 mL per vial unless your protocol specifies otherwise.
03 — After reconstitution
After reconstitution, refrigerate at 2–8°C. Use within the timeframe defined by your research protocol. Do not freeze reconstituted solutions. Avoid freeze–thaw cycles.
For qualified laboratory research only. Not for human or veterinary use. Follow your institutional SOPs for sterile technique and waste disposal.
DSIP is widely discussed in the preclinical literature around Peptides for longevity. This SKU is formatted for laboratories that need traceable sourcing and analytical documentation suitable for grant reporting and QA folders. For laboratory research only. Not for human consumption, clinical use, or veterinary applications without proper authorization.

FAQ — DSIP
Is this compound intended for human use?
No. It is sold strictly for research under appropriate oversight.
Do you supply certificates of analysis?
Yes — representative CoA and supporting analytical summaries are available for qualified laboratory buyers.
How should I choose a reconstitution solvent?
Base the choice on solubility, buffer compatibility, and stability data for your specific peptide and assay — follow your validated SOP.
Disclaimer: For in vitro and qualified preclinical research only. Not for human consumption, clinical trials, or veterinary applications without proper regulatory authorization.
DSIP (5 mg) is offered as a research-grade reagent for teams working in Peptides for longevity. Each batch is intended for documented R&D workflows — stability studies, receptor binding, in vivo models under IACUC, or bioanalytical method validation. We recommend qualifying each lot against your internal acceptance criteria before use in pivotal experiments.
For laboratory research only. Not for human consumption, clinical use, or veterinary applications without proper authorization.
Format: 5 mg as listed on the product label.
Appearance: lyophilized cake or powder unless otherwise stated; color may vary slightly batch to batch within specification.
Storage: keep sealed, protect from moisture and light, and store per your institutional SOP (frozen or refrigerated as validated for your workflow).
Reconstitution: use sterile solvents appropriate to solubility and stability; bacteriostatic water is common for many peptides but must match your validated procedure.
Documentation: request CoA summaries, SDS, and cold-chain handling notes from support when you place a qualified order.

Outstanding documentation and fast delivery
As someone running a tight research timeline, the 48-hour dispatch made a real difference. Received the CoA before the package even arrived, which allowed us to pre-plan our reconstitution protocol. The material dissolved cleanly and behaved exactly as expected in our assay. Highly recommended for CRO teams that need reliable, documented supply.

Consistent quality across multiple orders
Third order from peptides-pro and the quality has been consistent every time. We run our own in-house HPLC verification and the results align with the provided CoA. The customer support team was very responsive when I had questions about storage conditions for a longer-term experiment. Pricing is competitive for research-grade material.

Good quality, reliable partner for academic research
Used this supplier for a 6-month pharmacokinetics study. The peptide purity was consistently above 98%, which was critical for our in vitro work. The customs documentation was thorough and our package cleared without issues. Only minor feedback: would appreciate slightly more detailed storage notes per compound. Overall a very solid research supplier.
