Short answer: Log each compound as its own entry, even when they are in one syringe or one blended vial: compound, amount in mg or mcg, units drawn, the vial it came from and that vial's concentration, time, and injection site. Give every vial a name or lot number and a mix date. Change one thing at a time and hold it for a set period before judging it, write down symptoms and side effects with dates, and get baseline labs before adding something new. Without that, when you feel better or worse you will not know which compound to thank or blame.
A "stack" is two or more compounds used over the same period, such as BPC-157 with TB-500, or CJC-1295 with ipamorelin, sometimes on top of TRT. Stacks are where tracking goes wrong most often. Doses get mixed up between vials, blends hide how much of each compound went in, and several things change at once so no one can tell what did what. This is a practical method for keeping it straight. It does not recommend any stack or dose; for the evidence on specific compounds see our posts on BPC-157, TB-500 and GH secretagogues.
With one compound, if something changes you have one suspect. With three, you have three, plus any interaction between them, plus whatever else changed in your life that month. Human evidence for most popular stack peptides is thin, so your own records are often the only data you will have. Good records also make a clinic visit faster: your prescriber can see exactly what you took and when.
| Field | Why it matters |
|---|---|
| Compound | One entry per compound, even if they share a syringe. |
| Amount (mg or mcg) | The real dose. Units alone are meaningless without concentration. |
| Units or mL drawn | What you actually measured; lets you catch math errors later. |
| Vial (name or lot) and its concentration | Links the dose to a specific mix and batch. |
| Date and time | Timing patterns (morning vs night, fasted vs fed) are easy to forget. |
| Injection site | For rotation, and to spot site reactions tied to one product. |
| Notes | Anything unusual: a sting, a bubble, a missed or late dose. |

Once you have several open vials, the most common error is drawing from the wrong one, or using the right one with the wrong concentration in your head. Fixes:
Pre-blended vials (two or more peptides in one vial) are convenient, but they hide information. A blend has a fixed ratio, so you cannot change one compound without changing the others, and a single "dose of the blend" contains a different amount of each component.
This is the single most useful rule. If you add two compounds in the same week and feel different, you cannot tell which caused it. A simple pattern:
The same applies to stopping. If you drop two things at once and feel worse, you will not know which one mattered.
Which labs matter depends on the compounds. For GH secretagogues, the main measurable effect is on IGF-1, and the tesamorelin label also warns about glucose; see our GH secretagogue post. If the stack sits on top of TRT, the usual TRT labs still apply: see hematocrit and PSA. Record each result with its date and the day in your injection cycle.
Each compound in a stack runs out on its own schedule. Count doses per vial and check each vial's discard date separately. Our vial inventory guide walks through the math, including order-by dates.
Dose Track tracks multiple peptides at the same time, each with its own schedule and reminders. Each vial is tracked with its reconstitution, remaining volume and expiration date. When you log a dose from a blend, the app records it as tagged shots for each component, so your history shows how much of each compound you actually took. Injection sites are logged for rotation. You can also share a protocol or stack with a link, so a clinician or training partner sees exactly the same plan. Symptoms, side effects and lab results live on the same timeline as your doses.
