How to reconstitute Glow Blend (GHK-Cu, BPC-157, TB-500)

View guide

The materials you'll need and step-by-step instructions for safely mixing Glow Blend (GHK-Cu, BPC-157, TB-500) with bacteriostatic water.

Materials needed

Your Glow Blend (GHK-Cu, BPC-157, TB-500) vial (lyophilized)

Alcohol swabs

Bacteriostatic sterile water

3 mL syringes (Luer Lock tip)

25G or 27G needles (Luer Lock). Other gauges may also be acceptable.

Sharps container (optional)

Remove the caps

Remove the caps from both your Glow Blend (GHK-Cu, BPC-157, TB-500) vial and your bacteriostatic water vial.

Sanitize the rubber stoppers

Wipe down the rubber stoppers on both vials with alcohol swabs and let them dry for about 3 minutes.

Attach the needle

Take your 3 mL syringe and needle. Twist the needle's plastic hub into the Luer Lock tip on the syringe to secure it.

Draw the bac water

Pull back on the plunger to draw your desired volume of bacteriostatic water. If you overfill, just push the excess back in until you reach the right marker on the syringe.

How much bac water? Glow Blend (GHK-Cu, BPC-157, TB-500) typically comes in a 35 mg vial. We recommend 3–5 mL of bacteriostatic water, though anywhere between 1 mL and 3 mL is acceptable. For larger vials you can use up to 5 mL — more bac water makes microdosing easier, but insulin needles usually max out at 1 mL per injection. That means a lot of bac water might force you into multiple injections to hit your target dose. Unless you're microdosing, 2 mL per vial is a solid rule of thumb.

Insert the needle into the Glow Blend (GHK-Cu, BPC-157, TB-500) vial

With the bac water in your syringe, insert the needle into the Glow Blend (GHK-Cu, BPC-157, TB-500) vial at a slight angle to avoid pressure buildup.

Use a thin needle: Stick to 25G or higher to avoid damaging the rubber stopper. Higher gauge means a thinner needle.

Release the water gently

Let the water run gently down the side of the vial. Don't inject it forcefully.

Heads up: Sometimes the plunger pushes itself in as soon as the needle enters the vial. Hold the plunger back so you have full control over how fast the bac water enters.

Swirl to dissolve

Avoid shaking. Gently swirl, flip, and roll the vial to dissolve the powder.

Be patient: This usually takes 2 to 5 minutes of consistent swirling, mixing in a circular motion, and gently flipping the vial up and down. The water needs to run through the powder many times to fully dissolve it. Don't shake or get aggressive with it.

Check for full dissolution

The solution should be clear with no visible particles. If it's cloudy or clumpy, wait a minute and repeat the swirling step.

Cap, dispose, and store

Once you're done, cap the needle and dispose of it (ideally in a sharps container). Store the reconstituted Glow Blend (GHK-Cu, BPC-157, TB-500) vial in the fridge whenever it's not in use. It will stay good for approximately 30 days.

How to Store Glow Blend (GHK-Cu, BPC-157, TB-500)

Freeze the dry powder for long-term storage, or refrigerate it for up to four weeks. Once mixed with 3mL of bacteriostatic water, refrigerate and use within about a month, kept away from light.

Lyophilized Storage

-20°C long-term or 2–8°C for up to 4 weeks.

Reconstituted Storage

With 3mL bacteriostatic water, refrigerate at 2–8°C and use within 28 days.

How Long Should a Glow Blend (GHK-Cu, BPC-157, TB-500) Cycle Last?

This breaks down how long a typical Glow Blend (GHK-Cu, BPC-157, TB-500) cycle runs and what research suggests happens at each stage. Research shows that staying on a peptide continuously, without a break, may make it less effective over time.

That's why most research protocols build in a break between cycles, often called a washout period, to let the body reset before starting again.

Week 1-2: Initial tissue healing response begins
Week 2-4: Visible skin improvements may begin
Week 4-8: Collagen synthesis and regeneration effects
Week 8-12: Peak effects; optimal skin rejuvenation

Frequently Asked Questions About Glow Blend (GHK-Cu, BPC-157, TB-500)

Straight answers on reconstitution, dosing, and safety, everything you need to research with confidence. For research reference only.

Glow Blend is a combination product sold by research-peptide vendors that puts three peptides in a single vial: BPC-157, TB-500 (a thymosin beta-4 fragment), and GHK-Cu (a copper-binding peptide). Each is associated with a different mechanism: BPC-157 is studied for supporting blood vessel growth (angiogenesis) and gut, tendon, and ligament repair; TB-500 is studied for promoting cell migration and systemic tissue healing; and GHK-Cu is studied for its role in collagen and elastin production and skin/tissue remodeling. The rationale for combining them is that they target complementary parts of a healing and tissue-remodeling process, though no published human trial has evaluated the three compounds together as a fixed combination.

Vendor and community protocols commonly describe a 70 mg lyophilized vial reconstituted with about 3 mL of bacteriostatic water, added by directing the stream against the vial wall (not directly onto the powder) and gently rolling rather than shaking, yielding roughly a 23 mg/mL solution. Community-reported daily subcutaneous doses are often around 10 units (0.10 mL), delivering approximately 1.67 mg GHK-Cu, 0.33 mg TB-500, and 0.33 mg BPC-157 per injection. When the peptides are run from separate vials instead of a pre-blend, reported ranges include BPC-157 at roughly 250-500 mcg/day, TB-500 at roughly 2.5-5 mg twice weekly, and GHK-Cu at roughly 1-2 mg/day, each injected with its own syringe rather than mixed together. These figures come from vendor and community sources rather than clinical dosing studies, and no standardized human dose has been established.

Community protocols generally describe cycles of about 4-6 weeks on followed by 2-4 weeks off, with some extended protocols running 8-12 weeks on and 4-8 weeks off. The off-period is often tied to GHK-Cu "copper cycling" recommendations rather than to BPC-157 or TB-500 specifically. There is no clinically validated cycle length, and these schedules reflect anecdotal and vendor guidance rather than established research protocols.

Commonly reported effects include mild injection-site irritation (redness, itching, or soreness), short-term fatigue (particularly reported during TB-500 loading phases), and occasional headache. Because BPC-157 and TB-500 both influence angiogenic (blood vessel growth) signaling, sources caution that the combination may be unsuitable for people with active cancer or vascular conditions. These reports come from user and vendor sources rather than controlled clinical trials, so the full side-effect profile, especially with long-term or repeated use, is not well characterized.

Unreconstituted (lyophilized powder) is generally recommended to be stored frozen for longer-term storage, though some sources note it can remain stable for a few months at room temperature if sealed and kept away from light. Once reconstituted, it should be refrigerated (roughly 2-8°C / 35-46°F) and not frozen; reported stability after mixing ranges from about 1-2 weeks (TB-500 tends to degrade faster) up to about 30 days for the blend overall. Vendors generally recommend only reconstituting the amount you intend to use in that timeframe.

Glow Blend and its individual components are not approved by the FDA for human use and are sold by research chemical suppliers labeled strictly for laboratory or research purposes, not for human consumption. BPC-157 and TB-500 are also on the World Anti-Doping Agency's prohibited list for athletes. Because these are unregulated compounds, there is no guarantee of pharmaceutical-grade purity, dosing accuracy, or sterility from any given supplier, and published safety and efficacy data in humans is limited.

Some vendors describe extending the stack by adding a fourth peptide, KPV, for additional anti-inflammatory coverage (sometimes marketed as a "KLOW" stack). Aesthetic and wellness clinics also describe combining GHK-Cu-containing protocols with procedures like facials, lasers, or other injectables as part of a broader skin-focused regimen. As with dosing, these combinations are based on vendor and community practice rather than controlled studies, and any decision to combine compounds carries added uncertainty about interactions and cumulative side effects.

Reported timelines vary by which effect is being tracked: recovery- or repair-related effects (attributed to BPC-157 and TB-500) are sometimes reported sooner, while skin- and tissue-quality changes attributed to GHK-Cu are generally described as gradual, with visible changes typically judged over weeks to months rather than days. These are self-reported or vendor-described timelines, not results from controlled clinical measurement.
