What Metrics to Track in a Peptide Protocol: The Complete Logging Guide for Tracker Users

An effective peptide protocol tracking system captures four categories of data: (1) PROTOCOL data — what you took, when, and how much, (2) SYMPTOM data — how you felt subjectively each day, (3) OBJECTIVE data — measurable things like body weight, body composition, and lab values, and (4) CONTEXT data — sleep, exercise, diet, stress, and other factors that affect how the body responds to the protocol. Together, these four categories produce a complete picture of how the protocol is working. The most common mistake protocol users make: logging only protocol data (dose and timing) and ignoring the other three categories. Without symptom and objective data, you cannot tell whether the protocol is actually working. Without context data, you cannot tell whether changes are from the peptide or from other factors (like sleep or stress changes). Protocol data alone is necessary but not sufficient. **Protocol data** (log every injection or dose): - Date and time - Peptide name - Dose (in mcg, mg, or IU depending on the compound) - Injection site (left delt, right delt, left glute, right glute, abdomen, etc.) - Injection depth (subcutaneous vs intramuscular) - Any side effects at the injection site **Symptom data** (log daily or every few days): - Energy level (1-10 or simple descriptor) - Mood - Sleep quality from the previous night - Libido / sexual function - Appetite - Recovery from exercise - Any new or unusual symptoms **Objective data** (log weekly or at defined intervals): - Body weight (same time of day, same scale, same conditions) - Body measurements (waist, chest, thigh, arm if relevant) - Body composition (DEXA scan, InBody, BodPod if available; otherwise skip) - Resting heart rate and blood pressure - Lab values when available (testosterone panel, CBC, CMP, specific markers for the protocol) **Context data** (log daily alongside symptoms): - Sleep duration and quality - Exercise (type, duration, intensity) - Nutrition (rough caloric intake, protein intake, alcohol consumption) - Stress level - Work schedule or life events - Other supplements or medications taken that day The minimum effective logging: protocol data on every injection (required), symptom data every 3-7 days, objective data weekly, context data daily. Anything less than this will not produce enough data to identify patterns. Dosed is designed to make this logging frictionless — each category has dedicated fields and the app correlates them automatically over time so you can see patterns without manual analysis.

Protocol data is the non-negotiable foundation. Without accurate protocol data, nothing else matters. This is the first category you should nail down before worrying about anything else. **What to log for every injection or dose**: 1. **Date and exact time**: peptide half-lives vary from hours to days. For short-half-life peptides, timing matters for understanding how the body responds across the day. For long-half-life peptides, the day of the week matters more than the exact time. Either way, log timestamps. 2. **Peptide name and form**: be specific. 'Semaglutide 2.5 mg/mL reconstituted' is better than 'semaglutide.' If you are using multiple peptides in the same protocol (like ipamorelin + CJC-1295), log each one separately. Mixed injections should specify both components. 3. **Dose**: the actual dose administered, not the total vial size. If you have a 5 mg vial and you inject 250 mcg, log 250 mcg. The vial size is irrelevant; the amount going into your body is what matters. 4. **Injection site**: rotate injection sites and track the rotation. Injection site rotation prevents lipodystrophy (fat changes at the injection site) and ensures consistent absorption. Common rotation patterns: - Subcutaneous peptides: abdomen (4-6 spots), outer thighs (both sides), love handles, upper glutes. Rotate through 8-12 sites over a few weeks. - Intramuscular injections: deltoid, ventrogluteal, vastus lateralis (thigh). Rotate every injection. 5. **Injection depth and route**: subcutaneous (under the skin into the fat layer) vs intramuscular (into the muscle). Some peptides should be subq only (GLP-1 agonists, ipamorelin). Others can be either (testosterone). Track which route you used. 6. **Injection volume**: the total volume injected. Useful for tracking how much bacteriostatic water you used and for ensuring correct dose from a given reconstitution concentration. 7. **Any injection site reactions**: redness, swelling, bruising, tenderness, induration. Some sites bruise more than others; some peptides sting more than others. Tracking this over time reveals patterns. 8. **Time since last injection**: for peptides with specific timing requirements (like GHRH/GHRP peptides that should be injected on an empty stomach for maximum effect), track whether you hit the timing window. **Protocol changes and milestones**: - When you start a new peptide, note the start date prominently. - When you change dose (up or down), note the change date. - When you pause or end a cycle, note the end date and total duration. - When you change bacteriostatic water or reconstitution (new vial), note the change. **What NOT to log**: do not log the cost of the peptide, the source, or personal details that do not affect the protocol response. The logging should be about biological effects, not purchase history. Dosed provides templates for common protocols that preset most of the required fields — you just tap the injection and fill in the variable data (dose, site, any changes from the previous injection). This reduces logging friction to 15-30 seconds per injection.

Objective data is easy to capture but may not tell you what you care about. If your testosterone level goes from 350 to 700 ng/dL but you still feel terrible, the number is less important than the symptom. Symptom tracking is what connects the protocol to how you actually experience your life — and most protocol users skip this because it feels subjective and hard to quantify. **Why symptom data matters**: - Peptides often improve specific symptoms (energy, sleep, recovery, mood, libido, cognitive function) rather than single objective markers. - Side effects manifest as symptoms (fatigue, headaches, injection-site reactions, mood changes) before they show up in labs. - The protocol's success or failure is ultimately about how you feel and function, not just the numbers. - Patterns in symptoms over time reveal the real effects of the protocol. **How to log symptoms consistently**: 1. **Use simple 1-10 scales** for subjective categories. 1 = worst, 10 = best. Consistent scales are easier to compare over time than free-text descriptions. 2. **Log at consistent times**: same time of day, same conditions. Morning logging (right after waking up) captures sleep quality and morning energy. Evening logging captures overall day and any cumulative effects. 3. **Track the same categories every time**: pick 5-7 categories that matter to you and track them consistently. Do not add new categories in the middle of a protocol — you lose comparability. **Categories to consider**: - **Energy / vitality** (1-10): how energetic and motivated you feel throughout the day. Peptides that affect metabolism (GLP-1 agonists) and growth hormone (secretagogues) commonly affect this. - **Sleep quality** (1-10): how rested you feel from last night's sleep. Separately: hours slept (objective). Growth hormone secretagogues, BPC-157, and TB-500 all commonly affect sleep. - **Mood / mental health** (1-10): general emotional state. Not every protocol affects this, but some (especially testosterone-related) have significant effects. - **Libido / sexual function** (1-10): important for TRT users specifically. Separately track erectile function, morning erections, and interest. - **Recovery from exercise** (1-10): how quickly you bounce back from training sessions. Growth hormone secretagogues and BPC-157 commonly affect this. - **Cognitive function** (1-10): mental sharpness, focus, memory. Some peptides (nootropics, NAD+ precursors) specifically target this. - **Appetite** (1-10): how hungry you feel. GLP-1 agonists suppress appetite dramatically. Growth hormone secretagogues (ghrelin receptor agonists) increase appetite acutely. - **Pain or inflammation** (1-10, where 10 = pain-free): for recovery-focused protocols (BPC-157, TB-500), track joint pain and recovery markers. - **Side effects / unusual symptoms**: free text or checklist. Track injection site reactions, headaches, GI issues, unusual symptoms that appear only on protocol days. **Anchoring the scales**: a 7/10 energy day should feel similar across weeks and months. Without consistent anchoring, your scale drifts over time and the data becomes meaningless. One trick: write down what a 5/10 baseline feels like at the start of the protocol ('average day, not tired but not energized, can do my normal activities') and re-read it periodically to recalibrate. **The weekly review**: every 7 days, review your daily logs. Look for patterns — did energy drop on injection days? Is sleep improving over weeks? Are side effects persistent or transient? This weekly review is where the value of the data emerges. Dosed includes a daily symptom log with the standard categories plus custom fields you can add for your specific protocol. The weekly review tab automatically summarizes the past 7 days and flags any outliers or trends.

Objective data ties the subjective experience to measurable reality. If your energy is improving and your body fat is dropping, the data confirms what you feel. If your energy is improving but the objective data shows no change, either the effect is placebo or the measurements are not capturing the relevant change. **Body metrics to track (depending on protocol goals)**: 1. **Body weight**: daily is best for metabolic protocols (GLP-1 agonists for weight loss). Weekly is sufficient for most others. Always weigh under the same conditions: morning after urinating, before eating or drinking, minimal clothing, same scale. Natural fluctuation is 1-3 pounds per day from water and food — do not overreact to single-day changes. 2. **Body measurements**: waist, chest, hips, thigh, arm. Measure weekly with a flexible tape. Use a consistent location (e.g., waist at navel, not wherever is narrowest). Measurements capture changes in body composition that weight does not (muscle gain with fat loss can leave weight unchanged but measurements improve). 3. **Body composition**: DEXA scan or InBody every 3-6 months. DEXA is the gold standard but expensive ($100-200 per scan) and requires appointment access. InBody scales are more affordable and available at many gyms. Both are more accurate than at-home bioelectric impedance scales for tracking actual body composition changes. 4. **Photos**: front, side, and back photos every 2-4 weeks in consistent lighting and poses. Visual changes are often more dramatic than measurement changes and are the most motivating data point for most users. Store photos in a private dated folder. 5. **Performance metrics**: for protocols targeting performance (GH secretagogues, recovery peptides), track training metrics — weights lifted, reps completed, running pace, cardiovascular capacity, recovery times. Use whatever data your training app already provides and cross-reference with protocol data. **Lab values to track**: For TRT protocols: total T, free T, SHBG, estradiol, hematocrit, lipid panel, PSA (if over 40). Every 3-6 months. For GLP-1 protocols (semaglutide, tirzepatide for weight loss or metabolic health): fasting glucose, HbA1c (quarterly), lipid panel, liver enzymes (ALT, AST), comprehensive metabolic panel. Every 3-6 months. For growth hormone protocols (ipamorelin, CJC-1295, etc.): IGF-1 (the main marker of GH activity), fasting glucose, HbA1c (GH can affect glucose tolerance). Every 3 months. For BPC-157 or TB-500 (recovery peptides): no specific lab markers for these peptides, but baseline and periodic CBC and CMP are reasonable for general safety monitoring. For any long-term protocol: annual comprehensive panel (CBC, CMP, lipid panel, thyroid, vitamin D, any protocol-specific markers). **The timing rule for labs**: - Draw baseline labs BEFORE starting any protocol (ideally two draws on different days). - Draw follow-up labs 6-8 weeks after starting (testosterone takes 4-6 weeks to stabilize). - Draw routine labs every 3-6 months for ongoing monitoring. - Always draw at the same time of day (morning preferred) and at the same point in the injection cycle (trough, not peak). **The pattern that matters**: a single lab value tells you where you are. Multiple lab values over time tell you the TREND — which is what actually matters for protocol decisions. Dosed is built for this longitudinal tracking. Log each lab with the date, time, and any protocol changes since the last draw. The app displays trends over months and years alongside your symptom data and body metrics, making the patterns visually obvious. The goal of all this tracking is not the tracking itself. It is to make informed protocol decisions based on real data rather than guessing. Users who track consistently for 6-12 months have a dramatically better understanding of their own protocol response than users who do not — and they make better decisions as a result.
