Every batch independently third-party lab tested. Built for serious work in metabolic and endocrine research.
BPC-157 and TB-500 — the most studied repair research peptide combination — bundled at 2x the standard single-vial size.
Both peptides independently tested by Chromate Laboratories with ≥99% verified purity.
Both vials bundled at a meaningful discount vs. buying them separately.

The Recovery & Regeneration Research Stack pairs BPC-157 (10 mg) with TB-500 (10 mg) — both at double the standard 5 mg single-vial format. This is the canonical pairing in repair research literature, covering tissue repair, gut barrier function, cellular migration, and angiogenesis research models.
Both peptides are manufactured at compounding facilities operating under GMP-aligned standards and independently verified for purity and identity in every batch.
For research use only. Not for human consumption.
The Recovery & Regeneration Research Stack bundles BPC-157 and TB-500 — the canonical pair in repair research literature. Both vials come in 10 mg size (double the standard 5 mg). Sold for research use only.
Every lot of Recovery & Regeneration Research Stack is independently tested by Chromate Laboratories before release. We verify identity, purity (≥99%), and endotoxin levels. A Certificate of Analysis for your specific lot is available on request — just email admin@nxtstate.co with your order number.
Both lyophilized vials are shelf-stable at room temperature (away from direct light). Once reconstituted with sterile bacteriostatic water, vials should be refrigerated at 2-8°C and used within the standard stability window for repair research peptides.
Each order ships with the Recovery & Regeneration Research Stack unit(s) you purchased. Reconstitution materials (bacteriostatic water, syringes, alcohol pads) are available as separate products. We recommend ordering them together if it’s your first shipment.
Orders placed before 2pm ET ship same-day. After that, next business day. All shipments include tracking, and you’ll receive an email the moment your order is on the way. Free shipping on orders over $200.
Recovery & Regeneration Research Stack is compounded at facilities operating under GMP-aligned standards. We work exclusively with manufacturers who allow third-party lab verification of every batch we release.
