Research and education
Research guides.
Clear, plain-language guides to the compounds in the current catalogue, the documentation behind them, and the format questions worth asking before buying.
Research use only. No dosing or medical guidance.
Compound guides
Retatrutide
What Retatrutide is and where the research stands
A synthetic triple receptor agonist. Mechanism, regulatory status, stability, and what to check before buying.
BPC-157 / TB-500
Two peptides commonly studied together
What each is, how they are described in the literature, and what preclinical research has and has not established.
CJC-1295 / Ipamorelin
A pair studied on the growth hormone axis
Two peptides acting on different receptors within the same signalling system. What has been established in humans and what has not.
GHK-Cu
A copper-binding tripeptide
One of the more studied compounds in the peptide catalogue, and one of the more commonly misrepresented commercially.
Buyer’s guides
Format
Freeze-dried vs pre-filled peptide pens
Why format is the first thing to check on any peptide pen, and what happens to a compound once it enters solution.
Documentation
How to read a peptide Certificate of Analysis
Purity by HPLC. Identity by mass spectrometry. Independent testing. What each section of a COA does and does not tell you.
Reconstitution
How to use your pen
The ten steps to take an Optigenix pen from freeze-dried to ready. Video, written steps, dial conversion and storage.
Chemistry
Why peptides degrade
Hydrolysis, oxidation and aggregation. The three ways a peptide loses potency once it meets water.
Logistics
What happens to a pen in transit
Temperature swings, agitation, time. What international shipping does to a peptide pen, and why format decides what arrives.
Manufacturing
Lyophilisation
How freeze-drying preserves peptide structure and why every Optigenix pen starts as a dry powder.
Storage
Storing reconstituted peptides
Temperature, light, time. How to keep a reconstituted peptide potent for the full pen life.
Comparison
Are pre-filled pens actually stable?
The honest answer, from three angles: manufacturing, shipping, and the pen sitting on your kitchen counter.
