Most-researched peptides
Mechanism, dosage, FAQs — all research-grade.
BPC-157
A 15-amino-acid synthetic fragment of a protein found in gastric juice, studied for its broad systemic healing effects.
TB-500
A synthetic fragment of the naturally occurring protein Thymosin Beta-4, researched for tissue remodeling and recovery.

All news →GLP-1 Compounding Restrictions Tighten as FDA Resolves Shortages
With Semaglutide and Tirzepatide off the FDA shortage list, compounding pharmacies face new restrictions. Here's what changes for research-grade access.
First Human Trial of BPC-157 in Patellar Tendinopathy Reports Results
A small randomized human trial of injectable BPC-157 in patellar tendinopathy reports faster recovery and reduced pain vs placebo at 12 weeks. The findings are preliminary but the first of their kind.
Tirzepatide Approved for Sleep Apnea in Obese Adults
The FDA expanded Tirzepatide's label to include moderate-to-severe obstructive sleep apnea, citing >50% reduction in apnea-hypopnea events vs placebo.
Peptide FAQ
What does the PepComputer peptide calculator do?+
The PepComputer peptide calculator converts a vial size and bacteriostatic-water volume into a concentration, then computes the exact insulin-syringe units you'd draw for a target dose. It supports mg, mcg, and IU inputs, multiple syringe sizes, and projects doses-per-vial and vials-per-cycle.
What are peptides?+
Peptides are short chains of amino acids (typically 2–50) that act as signaling molecules. They are smaller than proteins and play roles ranging from immune regulation (Thymosin) to growth-hormone release (CJC-1295) to tissue repair (BPC-157).
Are peptides legal?+
Most research peptides are sold for laboratory and research use only. Some — like Semaglutide and Tirzepatide — are also FDA-approved prescription medications under specific brand names. Legality depends on jurisdiction, intended use, and source.
How do I start learning about peptides?+
Start with our peptide profiles and the BPC-157 and CJC-1295 pages — they're the two most-studied peptides for recovery and growth-hormone research, respectively. Use the calculator to understand reconstitution before reading any protocol.
Does PepComputer sell peptides?+
No. PepComputer is an independent calculator and education hub. We don't sell peptides, run display ads, or operate as an e-commerce site. The site is funded by the newsletter audience.
