The data on tendon and ligament healing is particularly compelling. It works even when injected away from the injury site.

NAD+ is foundational to my Blueprint protocol — it's central to cellular energy and DNA repair, and I track it closely.

BPC-157 is one of the most powerful healing peptides we have. I use it for gut healing, tendon repair, and systemic inflammation.

CJC-1295 is one of the most effective tools I've found for optimising growth hormone without suppressing your own axis.

BPC-157 upregulates growth hormone receptors in tendon fibroblasts. The animal data on tendon and ligament repair is quite compelling.

Frequently asked questions

What does “for research use only” mean?
Every compound listed on Pepnerd is intended strictly for in-vitro laboratory research and analytical work. Nothing here is a drug, supplement, or medical product, and none of it is for human or veterinary use, diagnosis, or treatment. These materials are not approved by regulators as medicines and may be subject to restrictions in your jurisdiction.
How is purity described?
Reference figures describe analytical purity targets for laboratory-grade material, typically established by methods such as HPLC and mass spectrometry. Always confirm specifications against the documentation supplied with a given batch before relying on them.
How should research peptides be handled and stored?
As a general laboratory reference, lyophilised peptides are usually kept cold and protected from light and moisture, and reconstituted material is handled under standard cold-chain practice. Follow your own institution’s protocols and the safety data for each specific compound.
How do I work out reconstitution and dosing figures?
Our free Reconstitution and Dosage calculators give reference figures for concentration, volume to draw, and how long a vial lasts. They are educational tools for laboratory handling only — not protocol or medical advice.
Can different compounds be combined?
Some compounds are studied alongside others to target complementary pathways, while certain pairs are flagged as do-not-combine. Each product dossier notes documented interactions, and the Stack Builder tool surfaces these for reference. This is educational signposting only.
