About this peptide

Crystagen is a tripeptide bioregulator (Pro-Glu-Asp) studied for effects on T-cell and B-cell populations in immune-system aging research. It is part of Vesta's tissue-specific bioregulator series, most often studied alongside Vilon and Thymalin for comparative immune-pathway research. Supplied as lyophilized powder. Reconstitute at 1–2 mg/mL in sterile or bacteriostatic water. Research use only.

Questions about Crystagen 20mg

How is Crystagen 20mg reconstituted?

+

Crystagen 20mg is supplied as lyophilized powder under nitrogen. Typical reconstitution is in sterile or bacteriostatic water; the exact concentration depends on your protocol. Our free reconstitution calculator computes mL per dose and insulin-syringe units from any combination of vial size, water volume, and target dose.

What is the HPLC purity of this batch?

+

Batch CY-2608 of Crystagen 20mg is verified at 99.0% HPLC main-peak purity, with confirmation of molecular weight by LC-MS and endotoxin screening by LAL assay. One vial of every batch is also shipped to an independent US-based third-party lab for blinded re-verification. The full COA — including the chromatogram, mass spec trace, and third-party report — is bundled with your order as a downloadable PDF.

How does QSC ship to the United States?

+

All orders ship cold-chain via DHL Express from our Guangzhou facility. Cold-pack is validated to hold under 8°C for 96 hours. Customs duties are prepaid by us — no surprise charges on delivery.

What payment methods are accepted?

+

ACH bank transfer (2% off, recommended), USDC / BTC / ETH crypto (5% off), Zelle, CashApp, Venmo, or wire transfer for institutional orders. We do not accept credit cards because card processors prohibit research-peptide merchants in their terms of service. Full payment-method details are on the shipping & payment page.

How stable is Crystagen after reconstitution?

+

Crystagen is light-sensitive after reconstitution; store reconstituted material refrigerated in amber vials. Typical stability is 4-6 weeks at 2-8°C in bacteriostatic water.

Can Crystagen be combined with NAD+ pathway compounds in research?

+

Crystagen is sometimes co-studied with NAD+ pathway compounds in mitochondrial and longevity research. The exact combination depends on your specific research question.
