STUDY NOTES 03 — DOSAGE
What CJC-1295 Ipamorelin Dosage Did Studies Use?
The amounts changed by drug, animal, and test. They are study facts, not directions for you.
What Amounts the Studies Used
What amounts did researchers use? No human study tested the two drugs together.
Human work tested CJC-1295 by itself. The men got 60 or 90 micrograms based on each kilogram they weighed.
The CJC-1295 shot went under the skin. Growth hormone rose 46%, and IGF-1, a growth-linked blood protein, rose 45% [1].
A 2009 CJC-1295 blood-protein study used the same range [6]. It checked changes after the shot.
One CJC-1295 study involved people with HIV. ClinicalTrials.gov listed it, but no main paper followed.
Its result therefore remains unclear. The 2006 mouse paper covered another study from 2006.
Mice got 2 micrograms each day [5]. Those mice were born without a normal growth message.
They don't stand for healthy people. In 1999, a 15-day rat study tested several amounts [4].
It measured bone length. In 2001, rats got three daily shots of 100 micrograms for each kilogram [8].
They were losing bone from steroids. In 2000, a 12-week rat study used 0.5 milligrams per kilogram each day [9].
It measured bone mineral. In 2009, rats got 0.01–1 milligrams for each kilogram by vein, four times daily [10].
That test watched the gut after surgery. These facts come from separate studies of CJC-1295 and ipamorelin.
They don't set your plan. Read the amounts as study labels, not a personal dose plan.
What Changes CJC-1295 and Ipamorelin Time in Blood
How long does each drug stay? One added part makes the largest difference.
Without that part, CJC-1295 acts like the body's short message. It lasts below 10–13 minutes [16].
With the added part, CJC-1295 holds onto albumin in blood. Human work puts its blood time near 6–8 days.
IGF-1, a growth-linked blood protein, stayed raised beyond 14 days [1]. That followed one dose in an early human test.
In rats, CJC-1295 was still found beyond 72 hours [2]. That supports a longer stay in blood.
Ipamorelin stayed in rat blood about 2 hours. Rats cleared it 5-fold more slowly than an older test drug called GHRP-6.
The rats passed 60–80% into bile and urine without breaking it down [7]. That finding doesn't prove safety.
A sound human blood-time study hasn't been published. The form without the added part stays below 30 minutes.
The long-lasting CJC-1295 form stays about 6–8 days. Ipamorelin stayed about 2 hours in rodents, not people.
The added CJC-1295 part changes time in blood. You don't have a sound human time for ipamorelin.
What the Study Shot Schedules Show
Study schedules changed with the drug form. They don't set a personal shot plan.
Human CJC-1295 work used the long-lasting CJC-1295 form once a week or less [1]. Its time in blood allowed that spacing.
The short CJC-1295 form leaves blood much sooner. Human data for once-to-twice daily use remain limited.
Animal ipamorelin studies used 1–3 daily amounts. One bone study used three shots under the skin [8].
A gut study used four doses by vein each day [10]. That plan belonged to sick rats after surgery.
How often should a person inject the pair? Published work can't answer that.
Rat work found a roughly 2-hour blood time. Human tests haven't set a schedule for the pair.
The studies explain why their schedules differed. Rat work doesn't set your schedule.
What Food and Sleep Do to the Timing
Food can mute a growth hormone burst. Eating raises insulin, which can press the body's brake.
That brake tells the growth gland to ease back. Fasting lowers insulin and may ease the brake.
One 5-day fast study followed men. Their bursts rose during 24 hours [11].
Their 24-hour hormone reading also rose. The study said the rise was unlikely to be chance.
That study didn't test this drug pair. It only helps explain the empty-stomach claim.
Should the pair be taken without food? Direct human timing tests haven't answered that.
Sleep adds another time question. The day's largest natural burst often comes in deep sleep.
One human study gave ghrelin in 4 doses. Each dose was 50 micrograms by vein over 3 hours [12].
Deep sleep and slow brain waves increased. That finding came from ghrelin, not ipamorelin.
Some researchers therefore look near bedtime. No direct human timing test of ipamorelin is published.
The pair wasn't tested in that fast. That is why the timing claim stays uncertain.
For you, the fasting claim remains a guess. It wasn't checked with the pair.
What the Studies Found Over Time
CJC-1295 raised growth hormone within hours in human work. IGF-1, a growth-linked blood protein, was higher at one week [1].
With the long-lasting CJC-1295 form, IGF-1 stayed raised up to 28 days. Later IGF-1 checks found the longer rise.
In rodents, ipamorelin brought a burst around 15–30 minutes. Its rat blood time covered a 2-hour span.
How long do the drugs take to work? The answer depends on what was measured.
Blood changes came within the first week. Body fat, muscle, and bone took longer to measure.
Animal studies watched body changes over 4–12 weeks. Early CJC-1295 work checked IGF-1 within 2 weeks.
Other animal work found changes at 4–8 weeks [4][8][9]. Human tests haven't set a result date for the pair.
A blood test is easier to time than a benefit. Your result date hasn't been set.
What Mixing and Cold Storage Do
This section covers lab handling, not home use. The powder is freeze-dried.
Labs add 0.9% benzyl alcohol to sterile water. That preservative helps slow germ growth.
Lab workers run the water down the vial wall. Hard shaking can make peptide pieces clump.
Once mixed, the drug can lose strength. Some broken parts were 25–500-fold less active.
Dry CJC-1295 vials were kept at −20°C for months. Mixed liquid was kept cold at 2–8°C.
The paper's own time limit still applied. Gentle mixing helped avoid clumps.
Blood breaks some short peptides down after a shot. One CJC-1295 form was made to slow that.
The CJC-1295 papers cover lab mixing, cold storage, and breakdown in blood. They don't give home instructions.
Read these as lab facts only. Your home use isn't covered by the papers.
