Everything a researcher new to GLOW needs in one place — what it is, how to reconstitute it, the published dosing reference, storage, the mistakes most beginners make, and answers to the questions we get asked most.
GLOW is Nova Biolabs' own three-peptide blend, combining GHK-Cu, BPC-157, and TB-500 in a single 70mg lyophilised vial. Rather than buying and reconstituting three separate compounds, GLOW pre-combines them at a fixed, research-relevant ratio — one vial, one reconstitution, one dosing reference to work from.
The name reflects the research angle: GHK-Cu is studied mainly in skin and collagen research, while BPC-157 and TB-500 are studied in tissue-repair and regenerative models. Together they cover a broader aesthetic-and-regenerative research profile than any single compound alone.
In short: GLOW = GHK-Cu + BPC-157 + TB-500, blended, in one vial, with a single published dosing reference — designed to be a simpler starting point than sourcing and combining all three yourself.
Is This Guide For Me?
This guide is written for researchers who are new to GLOW specifically — whether you've reconstituted other peptides before and are trying GLOW for the first time, or you're new to research peptides altogether. You don't need any prior experience with GHK-Cu, BPC-157, or TB-500 individually to follow it; every step below assumes you're starting from zero.
If you've already reconstituted peptides before, the reconstitution and dosing reference sections are the two you'll want — they're GLOW-specific and differ slightly from generic single-compound guidance because GLOW is a blend.
What Each Component Is Studied For
GLOW's 70mg vial is made up of three peptides at different amounts, each with its own distinct research background:
50mg · GHK-Cu
Skin & Collagen Research
A naturally occurring copper-binding tripeptide studied for its role in extracellular matrix remodelling and collagen-related signalling. GHK itself occurs naturally in human plasma and is known to decline with age.
10mg · BPC-157
Tissue Repair Research
A pentadecapeptide derived from a sequence found in human gastric juice protein, widely studied for tissue-repair signalling across in vitro and animal models.
10mg · TB-500
Angiogenesis & Cell Migration
A Thymosin Beta-4 fragment studied for roles in cell migration and pro-angiogenic effects, including endothelial cell migration relevant to wound-healing research models.
No clinical trial has measured outcomes for GHK-Cu, BPC-157 and TB-500 used together as a blend — the research above relates to each compound studied independently.
Reconstituting GLOW, Step by Step
GLOW arrives as a lyophilised (freeze-dried) powder and needs to be reconstituted with bacteriostatic water before use in research protocols. The process is the same general technique as any lyophilised peptide, with one GLOW-specific number to know: Nova Biolabs' GLOW dosing reference is built around 2.5ml of bacteriostatic water per 70mg vial.
1
Bring everything to room temperatureLet the GLOW vial and your bacteriostatic water sit out until both reach room temperature. Mixing cold solutions is the single most common cause of cloudiness in a freshly reconstituted vial.
2
Equalise vial pressureInsert a sterile needle half-filled with air through the rubber stopper before adding any liquid. The vial will draw in or release air to stabilise, which stops the vial "pushing back" and losing solution once water is added.
3
Add 2.5ml of bacteriostatic water, slowlyDraw 2.5ml into a syringe and inject it down the inside wall of the vial — not directly onto the powder. Going slowly here matters more than it seems; a fast stream directly onto lyophilised powder is the other common cause of a cloudy vial.
4
Gently swirl — never shakeRotate the vial gently between your fingers until it's fully dissolved and the solution looks clear. This can take a minute or two. Shaking introduces air and can damage peptide structure.
5
Refrigerate immediatelyOnce dissolved, store the vial at 2–8°C straight away. See Storage & Shelf Life below for how long it stays good.
Why 2.5ml specifically? At 2.5ml, GLOW's commonly cited 2.8mg starter dose draws to exactly 0.1ml — the 10-unit mark on a standard U-100 insulin syringe, which is easy to read accurately. You can reconstitute with a different volume, but the syringe markings in this guide assume 2.5ml. Use the dosing calculator to work out different volumes.
The Dosing Reference
GLOW is one of the few compounds Nova Biolabs publishes a specific phased dosing reference for, because it's a blend formulated in-house rather than a single off-the-shelf compound. This is a commonly cited research reference point drawn from how GLOW is typically discussed in the research community — not medical dosing advice, and not a substitute for your own independent research.
Starter Reference
2.8mg per injection — made up of 2mg GHK-Cu, 400mcg BPC-157, and 400mcg TB-4. This sits in the middle of a wider 1.4–4.2mg range that's commonly referenced, used here as a practical starting point rather than a fixed rule.
Why It's Phased, Not Flat
Rather than one flat daily amount for 12 straight weeks, the commonly cited GLOW protocol steps down in frequency over three phases. The logic behind phasing like this — starting more frequent and tapering — is a pattern borrowed from how many research peptide protocols are structured, on the reasoning that early, more frequent exposure followed by a taper is more commonly referenced than a constant flat dose for the full duration.

Syringe reference: Reconstituted with 2.5ml bacteriostatic water (see Reconstitution above), a 2.8mg dose draws to 0.1ml — the 10-unit mark on a standard U-100 insulin syringe. If you've reconstituted with a different volume, or want a different dose within the 1.4–4.2mg range, use the dosing calculator to find the correct draw.
Starting Below the Reference Point
Researchers new to GLOW commonly start at the lower end of the 1.4–4.2mg range for the first few injections of the Activation phase, rather than beginning at 2.8mg — simply to observe how a first-time reconstitution and draw goes before scaling up toward the commonly cited starter reference.
Handling Notes
A few practical points that come up specifically for researchers new to working with a reconstituted peptide solution:
Draw accurately, not quickly. A U-100 insulin syringe reads in 1-unit increments — take the extra few seconds to get the plunger exactly on the mark rather than eyeballing it.
Keep the vial stopper clean. Wipe the rubber stopper with an alcohol swab before each draw — a multi-use vial is only sterile for as long as the entry point stays clean.
Site rotation is commonly practiced. Using a different area for each injection, rather than the same spot repeatedly, is a widely referenced general practice for any repeated-injection research protocol.
One vial, multiple draws. GLOW's 70mg vial is designed to be drawn from repeatedly across the full 12-week reference protocol, not used once — see Storage & Shelf Life for how long it stays usable.
Not medical guidance: the notes above describe commonly referenced research practice, not personalised instructions. Nova Biolabs products are sold for research use only.
Storage & Shelf Life
Lyophilised (unreconstituted) GLOW is stable for up to 24 months when refrigerated at 2–8°C and kept out of light. Once reconstituted with bacteriostatic water, that shelf life shortens considerably.

Note: peptides degrade gradually rather than suddenly — a reconstituted vial past its usual window doesn't necessarily look any different, which is exactly why sticking to the 2–8 week guideline matters more than judging by appearance.
Common Beginner Mistakes
💧
Mixing cold water with a cold vial
The #1 cause of a cloudy reconstitution. Let both reach room temperature first — see step 1 in Reconstitution.
🌀
Shaking instead of swirling
Shaking feels like it should dissolve the powder faster, but it introduces air and can damage peptide structure. Gentle swirling takes longer but is the referenced technique.
🧊
Refreezing a reconstituted vial
Once reconstituted, GLOW should stay refrigerated, not go back in the freezer. Freeze-thaw cycles can damage peptide structure — refrigerate only, and use within the 2–8 week window.
📏
Guessing the syringe draw instead of calculating it
Because GLOW's dose is quoted in total mg across three separate peptides at different ratios, it's easy to misjudge the draw by eye. Use the dosing calculator rather than estimating.
⏱️
Starting at the full 2.8mg reference on day one
Most researchers new to GLOW start toward the lower end of the 1.4–4.2mg range for their first few draws — see Starting Below the Reference Point above.
GLOW vs KLOW & Stacking
KLOW is Nova Biolabs' more advanced blend — it takes the same GHK-Cu, BPC-157 and TB-500 base and adds a fourth peptide, KPV, for additional anti-inflammatory research focus, in an 80mg vial. GLOW is the three-peptide starting point; KLOW builds on it once you're familiar with how the base blend behaves.
Researchers who want more control over the GHK-Cu, BPC-157 and TB-500 ratio than GLOW's fixed blend offers sometimes source the three compounds separately instead — see our BPC-157 / TB-500 blend and GHK-Cu 100mg pages. The tradeoff is three vials and three reconstitutions instead of one.
Frequently Asked Questions
Is GLOW one peptide or several? +
GLOW is a blend of three peptides — GHK-Cu, BPC-157, and TB-500 — combined in a single 70mg lyophilised vial rather than three separate vials.
What's the difference between GLOW and buying GHK-Cu, BPC-157, and TB-500 separately? +
Buying separately gives you independent control over each compound's ratio and timing, at the cost of three vials, three reconstitutions, and three sets of measuring. GLOW pre-combines all three at a fixed research-relevant ratio in one vial, which is simpler for a first stack but less adjustable than buying them individually.
Is GLOW legal to buy in the UK? +
Nova Biolabs sells GLOW as a research chemical for laboratory and in vitro research use only — not for human consumption. It is sold on that basis, the same as any other research peptide on the site.
Do I need any prior experience to use this guide? +
No — this guide assumes no prior experience with GLOW or its individual components. If you've reconstituted other peptides before, the reconstitution and dosing sections are GLOW-specific and worth reading regardless, since the numbers differ from a single-compound vial.
What is the standard GLOW dosing reference? +
A commonly cited starter reference is 2.8mg per injection (2mg GHK-Cu, 400mcg BPC-157, 400mcg TB-4), within a wider 1.4–4.2mg range, phased across 12 weeks: daily for weeks 1–4, 5x per week for weeks 5–8, then 2–3x per week for weeks 9–12. See the Dosing Reference section above.
How do I reconstitute a GLOW vial? +
Bring the vial and bacteriostatic water to room temperature, equalise vial pressure with a sterile needle, inject the water slowly down the inside wall of the vial, gently swirl (never shake), then refrigerate immediately. Nova Biolabs' GLOW vial is referenced against 2.5ml of bacteriostatic water — see the full step-by-step above.
How long does a reconstituted GLOW vial last? +
Once reconstituted and refrigerated at 2–8°C, GLOW is commonly referenced as stable for 2–8 weeks. Unreconstituted (lyophilised) and kept refrigerated, it's stable for up to 24 months.
Why is my reconstituted GLOW vial cloudy? +
Almost always caused by mixing a cold vial with cold bacteriostatic water, or adding the water too quickly. Let both reach room temperature first and inject slowly down the inside wall — see Common Beginner Mistakes above.
How is GLOW different from KLOW? +
KLOW is Nova Biolabs' more advanced blend — it takes the same three-peptide GLOW base and adds a fourth peptide, KPV, for additional anti-inflammatory research focus, in an 80mg vial. See the GLOW vs KLOW section above.
