Frequently Asked Questions

What is a pre-mixed peptide?

A pre-mixed peptide is supplied as a ready-to-use liquid solution, the peptide has already been dissolved in a carrier solution (typically bacteriostatic water or saline) to a specific concentration. Unlike lyophilised vials, pre-mixed peptides require no reconstitution before research use. They offer convenience and precise, consistent dosing without additional preparation steps. All Stackpure pre-mixed peptides are +99% purity, cGMP certified with COA every batch.

How do pre-mixed peptides differ from vials?

Lyophilised vials contain freeze-dried peptide powder that must be reconstituted with bacteriostatic water before use. Pre-mixed peptides come as liquid solution, ready to use directly. Vials have a longer shelf life (12–24 months unreconstituted) but require additional preparation. Pre-mixed solutions are more convenient for standardised dosing in research but should be used within the stated shelf life once received and stored refrigerated at 2–8°C.

What peptides are available pre-mixed?

Stackpure stocks a comprehensive range of pre-mixed peptide SKUs including BPC-157, TB-500, CJC-1295, Ipamorelin, Epithalon, GHK-Cu, Sermorelin, PT-141, Thymosin Alpha-1, Selank, Semax, AOD-9604, Fragment 176-191, GHRP-6, MOTS-c, NAD+, Retatrutide, and many more. All are formulated to research-standard concentrations.

How should pre-mixed peptides be stored?

Pre-mixed peptide solutions should be refrigerated at 2–8°C immediately upon receipt and kept away from direct light. Do not freeze liquid formulations. Most pre-mixed peptides remain stable for 30–60 days when properly refrigerated. Check the COA and product label for specific stability data. Always store in original packaging.

Do you ship pre-mixed peptides internationally?

Yes. Stackpure ships research pre-mixed peptides to the USA, UK, Canada, and Australia. All orders include a third-party COA. Delivery is 1–3 business days to the USA, UK, Canada, and Australia. Pre-mixed orders are packed with cold protection for transit stability.
