PepMetric is a research-grade peptide platform featuring a free reconstitution calculator, AI-powered protocol advisor, peptide dosing database, dose logging tools, bloodwork tracker, and a shop for research peptides including BPC-157, GHK-Cu, Retatrutide, Tesamorelin, Epitalon, Follistatin, Selank, and more.

How do you reconstitute BPC-157?

Mix a 5mg BPC-157 vial with 2mL of bacteriostatic (BAC) water to achieve a concentration of 2.5mg/mL or 25mcg per insulin unit. A standard 250mcg dose requires 10 units on a 100-unit insulin syringe. Use PepMetric's free reconstitution calculator to auto-calculate units for any vial size and dose.

What is the recommended dose for GHK-Cu?

GHK-Cu is typically dosed at 1–2mg per injection subcutaneously (SubQ). With a 50mg vial reconstituted in 2mL BAC water (25mg/mL), a 1mg dose requires 4 units on a 100-unit insulin syringe. Zinc supplementation (15–50mg/day) is commonly paired with GHK-Cu.

How much BAC water should I use to reconstitute peptides?

Most peptides are reconstituted with 1–2mL of bacteriostatic water. Use PepMetric's free peptide reconstitution calculator to get the exact syringe units for your specific vial size and desired dose in mcg.

What peptides are best for recovery and healing?

BPC-157 and Thymosin Beta-4 (TB-500) are the most widely researched peptides for tissue repair and recovery. BPC-157 is typically dosed at 250–500mcg SubQ near the injury site, cycled 6–8 weeks on, 2–4 weeks off.

What is Retatrutide and how does it work?

Retatrutide is a triple receptor agonist (GLP-1, GIP, and glucagon) developed by Eli Lilly. In Phase 3 trials it produced up to 28.7% weight loss — the highest ever recorded in a Phase 3 obesity trial. It is dosed once weekly SubQ, starting at 0.5mg and titrating up to 8–12mg over 12 weeks.

What is Epitalon used for in research?

Epitalon is a synthetic tetrapeptide (Ala-Glu-Asp-Gly) studied for its ability to activate telomerase and extend cellular lifespan. It is typically dosed at 5–10mg SubQ daily for 10–20 consecutive days, repeated 2–3 times per year.

What is Follistatin and what does it do?

Follistatin (FST-344) is a myostatin inhibitor that neutralizes GDF-8, removing the brake on muscle protein synthesis. Research peptide doses range from 100–200mcg SubQ daily for 10–20 day cycles. Do not exceed 200mcg/day.

What is Selank used for?

Selank is a synthetic heptapeptide anxiolytic and nootropic derived from tuftsin. It is studied for anxiety reduction without sedation, cognitive enhancement, memory, and stress resilience. Typical dose is 300–600mcg intranasally 2–3x daily or 200–400mcg SubQ once daily.
