Why we do not advocate for use
Peptides are investigational compounds. The majority have not been approved by the FDA or any regulatory body for human use outside of controlled clinical trials. We cannot and do not recommend that anyone self-administer, purchase, or use these substances.
Providing a calculator is not an endorsement. It is the same reason a chemistry textbook includes measurement tables - knowledge is not permission. Every individual is solely responsible for their own decisions, and those decisions should be made with a licensed physician.

Why labs need this tool
Research laboratories working with lyophilized peptides face a precise reconstitution problem every time they open a new vial. Getting the BAC water volume wrong by even a small margin shifts every downstream concentration and dose - corrupting entire experimental runs and wasting expensive compounds.
Labs use calculators like this to:
Confirm the correct solvent volume per vial weight (mg)
Calculate concentration in mcg/unit or mg/mL for precise pipetting
Standardize dosing across multiple vials or batches
Cross-check manual math before running in-vivo or in-vitro protocols
Precision reconstitution is the foundation of reproducible research

How to use Glow Calc
Pick your blend - GLOW or KLOW - at the top. The recipe (mg per compound) is fixed and shown under Vial Contents.
Enter how much bacteriostatic water you reconstituted the vial with, under Vial Contents.
Either drag the slider under Draw Line to any unit mark, or go to Target Draw, pick a compound, type the dose you want, and hit Set Draw.
Read the marked line on the syringe - that's exactly where to pull the plunger to. The chips above the slider show what you're getting of every compound at that draw, in both mcg and mg.

How this calculator reads
A U-100 insulin syringe marks 100 units to 1 mL - each unit line is 0.01 mL. Since every compound in a GLOW/KLOW vial is dissolved together, they come out of the needle in fixed proportion: change the water volume and every compound's concentration shifts together. Set your reconstitution volume on the left, then either drag the draw line yourself or tell the calculator a target dose for one compound and it'll calculate the exact unit mark - and show what all the other compounds work out to at that same draw.
Compound research notes
These are summaries of preclinical/research literature, most from animal or in-vitro studies - none of these compounds are FDA-approved therapeutics. This is background reading, not medical advice or a usage recommendation.
Blood work before any research
Not medical advice. This is a general reference list of panels people commonly discuss checking before starting, and periodically during, research peptide use - it is not a prescription or a complete list. Only a licensed clinician can tell you what's appropriate for your history, age, sex, and the specific compound. Get a real baseline before you start, so you actually have something to compare against later.
CMP - electrolytes, glucose, kidney & liver enzymes in one panel
Lipid panel - cholesterol, triglycerides, HDL/LDL
Metabolic / insulin resistance
Fasting glucose + fasting insulin - together give HOMA-IR, a standard insulin-resistance estimate
HbA1c - ~3-month average blood sugar
Thyroid & inflammation
TSH, Free T4, Free T3 - thyroid function
TPO / TgAb antibodies - if autoimmune thyroid issues are suspected
hs-CRP - high-sensitivity marker of systemic inflammation
Liver & kidney
ALT, AST, GGT, bilirubin - liver stress/damage
Creatinine, eGFR, BUN - kidney function
Male-specific
Total & free testosterone, SHBG
LH, FSH - pituitary signaling
Estradiol (sensitive assay)
PSA - if age-appropriate
Female-specific
Estradiol, progesterone - timing relative to cycle matters
LH, FSH
Total/free testosterone, SHBG
Prolactin, and AMH if fertility is a factor
A one-off panel tells you where you stand today; retesting on a schedule (e.g. before, a few weeks in, and after) is what actually lets you or a clinician catch a problem early.

Zinc & copper balance (GHK-Cu research)
Not medical advice. General reference only - confirm any supplementation plan against real bloodwork and a licensed clinician, not this list.
GHK-Cu delivers bioavailable copper directly into tissue. Zinc and copper share intestinal absorption transporters and are kept in balance partly through metallothionein; sustained copper exposure without a zinc offset can gradually push zinc status down, and the reverse is true of excess zinc suppressing copper. This is why copper-peptide research literature consistently flags zinc status as something to track alongside a GHK-Cu protocol, not something to ignore.
General reference ranges commonly cited in zinc-copper interaction and supplementation literature:
Target dietary ratio: roughly 8:1 to 15:1 zinc to copper is the range most commonly cited to avoid displacing either mineral.
Women: RDA is 8 mg elemental zinc/day (11 mg/day if pregnant; upper intake ~40 mg/day).
During an active GHK-Cu research cycle: many practitioners running longer protocols use 15-30 mg elemental zinc daily, taken several hours apart from copper peptide administration so the two don't compete for absorption in the same window.
Confirm, don't guess: serum zinc, serum copper, and ceruloplasmin can all be checked on a standard blood panel to see where you actually stand before adjusting anything.
Some longer-running protocols build in a short zinc-focused break (1-2 weeks) after several consecutive weeks of copper peptide use. This is common anecdotal practice in the research community, not an established clinical guideline.
Reducing GHK-Cu injection sting
GHK-Cu is one of the more commonly reported peptides for a stinging or burning sensation at the injection site. A few things that are widely reported to reduce it:
Let it warm up. A vial straight out of the fridge stings more going in - pull it out and let it sit at room temperature for 10-15 minutes before drawing.
Make sure it's fully dissolved. Any undissolved powder left in solution is more irritating on injection - gently swirl (don't shake) the vial until it runs clear.
Inject slowly. Pushing the plunger fast increases pressure and irritation in the tissue - a slow, steady push over several seconds is much better tolerated.
Rotate sites. Repeated injections into the same small area compound irritation over time - spread injections across different sites.
Anti-itch cream after, if needed. A thin layer of an over-the-counter hydrocortisone or antihistamine cream on the injection site after injecting is commonly used for residual redness or itching. If a reaction is severe, spreading, or not improving, stop and talk to a clinician.
