Step 1: Understand What You’re Combining

CJC-1295 and Ipamorelin are paired because they hit growth hormone release through two different mechanisms. CJC-1295 is a growth hormone-releasing hormone (GHRH) analog that raises the baseline amount of GH your pituitary can secrete, while Ipamorelin is a ghrelin-receptor agonist (a GH secretagogue) that triggers a pulse of release without meaningfully touching cortisol or prolactin. Used together, the two are thought to produce a stronger, cleaner GH pulse than either compound alone, which is why the combination shows up so often in peptide research communities. Before you draw up a single dose, it’s worth knowing which version of CJC-1295 you have — the DAC (Drug Affinity Complex) version extends half-life to days, while the non-DAC version (sometimes sold as CJC-1295 without DAC or confused with Mod GRF 1-29) clears in under an hour, which changes dosing frequency entirely. Mixing these up is the single most common protocol mistake people make, so confirm the exact compound name on your vial label before planning anything else.

Step 2: Reconstitute Both Peptides Correctly

Both peptides typically arrive as lyophilized (freeze-dried) powder that needs to be reconstituted with bacteriostatic water before it can be drawn into a syringe. A common approach is reconstituting a 2mg vial of Ipamorelin or non-DAC CJC-1295 with 2mL of bacteriostatic water, which yields a concentration of 1mg/mL — a ratio that keeps the math simple when you’re calculating microgram doses on an insulin syringe. Once mixed, both peptides are sensitive to heat and light and should be stored in the refrigerator, where most peptide manufacturers and compounding references note stability generally holds for around 2-4 weeks. Getting the concentration wrong at this stage cascades into every dose you draw afterward, so it’s worth double-checking your math rather than eyeballing it. This is exactly the kind of calculation that’s easy to fumble by hand — Pep’s reconstitution calculator handles the vial size, water volume, and target dose conversion automatically so you’re not doing unit conversions with a shaky pipette in hand. For a deeper walkthrough of reconstitution math specifically, see this peptide reconstitution calculator guide.

Step 3: Set Your Starting Dose

Most protocols in circulation dose CJC-1295 (non-DAC) and Ipamorelin together at 100-300 mcg each per injection, typically 1-3 times per day. Because GH secretagogues work on a pulsatile system, more isn’t automatically better — receptor desensitization is a real concern with GHRP-class peptides, which is part of why many protocols include planned breaks. A conservative starting point is 100 mcg of each compound once daily for the first week, giving you a baseline to judge tolerance before adding a second daily dose. If you’re using CJC-1295 with DAC instead, the dosing structure changes completely: because its extended half-life keeps GHRH elevated for days, it’s generally dosed only 1-2 times per week rather than daily, and stacking it with daily Ipamorelin requires a different mental model than a non-DAC protocol. Whichever version you’re running, write the exact mcg amount, compound, and time down before you draw the first dose — a written or logged plan is what prevents dose creep three weeks in.

Step 4: Time Your Injections Around Sleep and Meals

Growth hormone secretagogues are typically timed around the body’s natural GH rhythms rather than dosed at a fixed clock time regardless of context. A common pattern is injecting immediately before bed, since natural GH pulses are highest during early slow-wave sleep, and again upon waking on an empty stomach. Food — particularly carbohydrates and fat — can blunt the GH response because elevated blood glucose and insulin interfere with secretagogue signaling, so most protocols recommend fasting for at least 20-30 minutes before and after injection, with some going longer. If you’re training, a pre- or post-workout dose is another common third slot, since exercise itself is a natural GH stimulus and some users stack the peptide dose around it. The exact timing matters less than consistency: injecting at wildly different times relative to meals and sleep from day to day makes it far harder to tell later whether a symptom or a plateau is related to the protocol or just to that day’s timing.

Step 5: Rotate Injection Sites Deliberately

CJC-1295 and Ipamorelin are given as subcutaneous injections, usually in the abdomen, thigh, or upper glute area, and like any repeated subcutaneous injection, using the same spot repeatedly raises the risk of lipohypertrophy — a lumpy buildup of fat tissue under the skin from overuse. A simple rotation habit is dividing the abdomen into quadrants and moving clockwise with each injection, resting each site for several days before returning to it. This matters more with a twice- or thrice-daily protocol than a once-weekly one, simply because the same tissue gets hit far more often. Tracking which site you used last is easy to lose track of by day 10 of a multi-dose-per-day protocol, which is where a body map inside Pep becomes useful — it flags sites you’ve overused and suggests the least-recently-used spot so you’re not relying on memory. Rotating deliberately, not just haphazardly, is what keeps a multi-week protocol comfortable to stick with.

Step 6: Track Symptoms and Adjust

Reported side effects with the CJC-1295/Ipamorelin combination generally include injection-site redness, mild water retention, headache, flushing, and occasionally increased hunger, since ghrelin-receptor activity is also tied to appetite. None of these are usually severe, but they’re worth logging with a severity score rather than just remembering vaguely — patterns often only become obvious after two or three weeks of entries. If headaches consistently show up within a few hours of the evening dose but never the morning one, that’s a signal worth acting on, whether that means adjusting timing or dropping the dose back to 100 mcg. Pep’s symptom logging lets you tag each entry to the specific compound and dose, so when you look back at 30 days of data you can see, for example, that appetite spikes cluster around the Ipamorelin dose specifically rather than CJC-1295. That kind of compound-level breakdown is much harder to reconstruct from memory or a paper log after the fact.

Step 7: Review Adherence and Progress Monthly

A protocol only produces meaningful data if it’s actually followed consistently, and self-reported adherence tends to be optimistic — people remember the doses they took and forget the ones they skipped. Setting a monthly review checkpoint gives you an honest look at how many scheduled doses you actually hit, how consistent your timing was relative to meals and sleep, and whether symptom trends are moving in the direction you’d expect. Pep’s adherence tracking shows this automatically as a percentage against your logged schedule, alongside inventory alerts so you’re not discovering a vial ran dry mid-week and unintentionally skipping days. If you’re also running body composition tracking, correlating weight and measurement trends against your adherence percentage for that same month tells you far more than looking at either number in isolation. Over three or four monthly reviews, this is usually when patterns — a plateau, a side effect trend, a timing issue — become clear enough to act on with confidence rather than guesswork.

Frequently Asked Questions

How much CJC-1295 and Ipamorelin should I take together?

Most non-DAC protocols use 100-300 mcg of each peptide per injection, given 1-3 times daily. CJC-1295 with DAC is dosed very differently, typically just 1-2 times per week, due to its much longer half-life.

What’s the difference between CJC-1295 with and without DAC for dosing purposes?

CJC-1295 without DAC clears within about an hour, so it’s dosed multiple times daily alongside Ipamorelin. CJC-1295 with DAC has a multi-day half-life and is dosed only once or twice weekly, which changes the entire protocol structure.

When is the best time to inject CJC-1295 and Ipamorelin?

Common timing is immediately before bed and upon waking, both on an empty stomach, since these align with the body’s natural GH pulse windows. Food, especially carbs and fat, can blunt the secretagogue response if eaten too close to injection.

How long does reconstituted CJC-1295/Ipamorelin last?

Once mixed with bacteriostatic water and refrigerated, both peptides are generally considered stable for about 2-4 weeks, though this varies by manufacturer guidance. Keeping vials cold and away from light helps preserve potency.

What side effects should I watch for on this protocol?

Commonly reported effects include injection-site redness, mild water retention, headache, flushing, and increased hunger. Logging these with severity scores over time makes it easier to spot patterns tied to a specific dose or timing.
