New here? Start with this.
A plain-English starting point for anyone new to peptides, GLP-1s, or TRT. No jargon walls, no gatekeeping, no forum culture. Just the words, what they mean, and what to expect.
We explain the words. We never tell you what to take.
“I stared at a vial with no idea what half the words meant. I built this because I was lost in exactly the same spot.”
Glossary
The ones you’ll actually see on a vial, a forum, or a doctor’s note.
Reconstitution
Mixing a dry powder peptide with sterile water so it can be drawn into a syringe.
Full definition →Bacteriostatic water
Sterile water with a preservative that keeps a mixed vial usable for a few weeks.
Full definition →Subcutaneous
Injected into the fat layer just under the skin. Short needle, shallow angle.
Full definition →Cycle / off-cycle
A stretch of weeks on a compound, followed by a stretch off to give your body a break.
Full definition →Titration
Easing a dose up or down gradually over weeks, rather than jumping straight to a target.
Full definition →IU (International Unit)
A dose unit used for some peptides. Not the same as milligrams.
Full definition →mcg vs mg
1,000 micrograms (mcg) equals 1 milligram (mg). Easy to misread on a label.
Full definition →GLP-1 agonist
A class of drugs (semaglutide, tirzepatide) that mimic a gut hormone tied to appetite.
Full definition →Half-life
How long it takes for half of a dose to clear your system. Drives dosing frequency.

Full definition →Loading dose
A larger starting dose some protocols use to reach steady levels sooner, before settling to a maintenance amount.

FAQ
No. TRKD+ is a tracker and glossary. We don't sell, source, or link to anything you can buy. Where you get compounds is between you and your provider.
Anything you inject into your body should come from and be overseen by a licensed provider. TRKD+ won't tell you otherwise, and it won't help you skip that step.
Your logs are saved to your TRKD+ account and sync across devices you sign in on. We don't sell your data, run ads, or share it with insurers or employers. See the Privacy Policy for details.
A spreadsheet can't show which injection sites have rested longest, read your Apple Health data, or give you a plain-English glossary at 11pm when you're staring at a vial.
Yes. Everything TRKD+ does today is free, and it stays free. Any paid features will be optional extras added on top.
