Why these compounds
Why Lumen groups tirzepatide with three repair and skin compounds
Lumen is the tirzepatide kit. Its core is the dual GLP-1 and GIP agonist studied in the SURMOUNT obesity trials. The other three vials come from repair and skin research, a tendon-cell record, a copper-peptide gene-expression record and an antioxidant skin record, which is why the kit is described as weight, tissue repair and skin.
Tirzepatide · Dual agonist
Two of the five Lumen vials: the dual GLP-1 and GIP receptor agonist at the centre of the kit.
Studied in: Adults with obesity in the SURMOUNT-1 trial (Jastreboff et al., 2022) and in the SURMOUNT-4 maintenance trial (Aronne et al., 2024).

Tirzepatide price per vial→BPC-157 · Tissue repair
The tissue-repair vial in Lumen.
Studied in: Tendon fibroblasts in culture, where it promoted proliferation and migration (Chang et al., 2014).
Sources: Chang CH, Tsai WC, Hsu YH, Pang JS (2014), Molecules
BPC-157 price per vial→GHK-Cu · Copper peptide
The skin vial in Lumen: a copper-binding tripeptide.
Studied in: Gene-expression data on regenerative and protective actions, reviewed by Pickart and Margolina (2018).
Sources: Pickart L, Margolina A (2018), International Journal of Molecular Sciences
GHK-Cu price per vial→Glutathione · Antioxidant tripeptide
The antioxidant vial in Lumen.
Studied in: A human study of antiaging and antimelanogenic skin endpoints (Weschawalit et al., 2017).
Glutathione price per vial→
Lumen sets one large human record, tirzepatide in SURMOUNT-1 and SURMOUNT-4, beside three compounds whose published work is preclinical or small-scale. No study pairs tirzepatide with BPC-157, GHK-Cu or glutathione, so the kit names a research area and reports no combined finding.

What buyers said about the vials in Lumen
4.93 · 41 reviews from orders that contained these vials. Published word for word.
heard a couple guys talking about them in a facebook group for lifters, mostly just shipping reliability stuff. checked out their site that night and the way they laid out batch numbers per order was honestly better than any other vendor i had tried over the last year
box came thursday evening undamaged. ghk clear selank amber like it should be seals tight foam snug batch numbers legible under normal kitchen light. nothing wrong with this order at all
the cold pack was still frozen when i cracked the box open which at this time of year feels like a small miracle. both vials centered seals clean labels readable batch numbers matched what the site shows for these two skus
third order from these guys. caps are tighter this time compared to last month, and the tray was a new design with a little ridge that keeps the vials from rolling. i sent the semax off to a reference lab up the street, came back at 99.2% assay, hplc. tracking was smooth, app updated every step. box was about two pounds, heavier than i guessed for three vials. all good.
third order from them in four months and the consistency is honestly what keeps me coming back. box was small light undamaged, all three vials sealed tight with clear liquid inside except sluu which had that faint amber tint again and i am pretty sure that is normal for this one at least
gemini suggested them when i was comparing vendors for a friend who travels a lot. did my own verification after that, batch numbers all check out on the site, both vials plus the ghk arrived sealed properly with clear liquid and no shifting in the tray
$401 for 5 vials, $216 below retail.
Lumen peptide stack: buyer questions
Where can I buy the Lumen peptide stack?
Peptara Labs sells the Lumen stack on this page as a single cart line: 5 vials of Tirzepatide, BPC-157, GHK-Cu and Glutathione for $401. The Lumen kit ships worldwide, the United States included, in 5 to 10 business days with guaranteed delivery or a full refund. The batch certificate for each Lumen compound is published on the COA page.
How much does the Lumen stack cost?
$401 for 5 vials, an average of $80.20 a vial. Bought one at a time at catalog retail, the same 5 vials come to $617, so the Lumen kit is $216 lower. The Lumen stack rate applies to the stack and to nothing else in the same order: no code or multi-vial tier is added on top of it, and anything else in the cart is priced on its own terms. The stack's other compounds are also available on their own product pages at the usual catalog price. Tirzepatide single vials are sold out; it is available in this stack.
What comes in the Lumen stack?
2 vials of Tirzepatide, 1 vial of BPC-157, 1 vial of GHK-Cu, 1 vial of Glutathione, in one box with bacteriostatic water, a printed reference with the reconstitution math, and the batch certificate for what shipped. Each of the 5 Lumen vials holds one compound and is reconstituted and stored on its own.
How can I check the purity of the Lumen vials?
Match the lot printed on each Lumen vial to its certificate on the COA page. For this kit that is: Tirzepatide, lot TIRZ-260420-A, 99.31% HPLC purity; BPC-157, lot BPC-260408-A, 99.04% HPLC purity; GHK-Cu, lot GHKCU-260417-A, 99.62% HPLC purity; Glutathione, lot GTH-20260607-18, 97.12% HPLC purity. The released Lumen certificates are issued by Titreon Analytical and published in full.
Is Lumen the only way to buy tirzepatide?
Yes. Lumen is the only way to buy Tirzepatide at Peptara Labs: single Tirzepatide vials are sold out, and Tirzepatide is available in this kit.
How is Lumen different from Phoenix?
Lumen centers on tirzepatide, a dual agonist with two vials in the kit, and adds GHK-Cu for skin. Phoenix centers on retatrutide, a triple agonist, and pairs it with BPC-157 and glutathione, two vials of each. Both are weight-research groupings, and neither has been studied as a set.
Is the Lumen stack for human use?
No. The Tirzepatide, BPC-157, GHK-Cu and Glutathione vials are sold for research use only, not as an approved therapy, and this page gives no dose, schedule or protocol. No study has tested the Lumen grouping as a set, so there is no combined result to report, and any decision about a research compound belongs with a qualified clinician.
