I’ve been in the peptide space for over ten years.
And if there’s one stack that keeps coming up in conversations with serious people who actually know what they’re doing, it’s this one.
CJC-1295, Ipamorelin, and Tesamorelin together.
Three peptides. Different mechanisms. One goal: get your growth hormone working the way it’s supposed to so your body can actually do its job.
I’ve run versions of this stack myself. I’ve watched what it does for people in their 40s and 50s who feel like their body stopped responding to everything they were doing right. The results are hard to argue with.
Here’s what you need to know…
What Are CJC-1295 and Ipamorelin
These two are almost always talked about together, and for good reason.
CJC-1295 is a growth hormone releasing hormone analog. Its job is to signal the pituitary gland to produce more growth hormone. It has a long half-life, which means it keeps that signal going for an extended window after you inject it.
Ipamorelin is a growth hormone secretagogue. It works on a different receptor but points at the same target. It causes a clean, targeted pulse of growth hormone release without spiking cortisol or prolactin the way some older compounds do.
Together they hit two separate pathways and amplify each other’s effect. More signal. More release. Better results than either one alone.
Peptides can get expensive, but as an FYI - BioEdge is doing 15% off this month (code MARS15 at bioedgepeptides.com), one of the few suppliers that consistently delivers what their lab reports claim.
What Tesamorelin Adds
Tesamorelin is where this stack gets interesting.
It’s a stabilized form of growth hormone releasing hormone, originally developed and FDA-approved for reducing visceral fat in specific patient populations. It’s one of the most studied GH peptides available, and the research behind it is solid.
What it does particularly well is target stubborn abdominal fat. The kind that doesn’t move no matter how clean you eat or how hard you train. For people in their 40s and 50s dealing with that specific problem, Tesamorelin is worth understanding.
Running it alongside CJC-1295 and Ipamorelin gives you a tri-peptide approach that covers growth hormone release, pulse optimization, and direct fat mobilization at the same time.

The Benefits of Running This Stack
Here’s what people actually experience when they run this combination consistently.
Muscle growth is the one most people are after. When growth hormone levels go up and stay elevated, protein synthesis improves. Muscle repair after training is faster. Over a full cycle you’ll see real changes in how your muscle looks and feels.
Fat loss, especially around the midsection, is the other big one. Growth hormone is directly involved in how your body mobilizes and burns stored fat. Tesamorelin specifically targets visceral fat. Running this stack while eating and training right accelerates what would otherwise take much longer.
Recovery improves noticeably. Most people report this within the first few weeks. Soreness that used to last three days starts clearing in one. Sleep deepens. That’s the growth hormone doing what it’s supposed to at night.
Strength and performance follow from the muscle and recovery improvements. You’re training better, recovering faster, and building more tissue. The performance gains are a natural result of the other things working.
CJC-1295 and Ipamorelin Dosage
The standard protocol most people run looks like this:
CJC-1295 at 1mg to 2mg per week. Some people split this into two injections, some run it once weekly given the long half-life. Either approach works.
Ipamorelin at 200mcg to 300mcg per injection, two to three times daily. Most people run it morning, pre-workout, and before bed. The pre-bed injection is important because that’s when your natural growth hormone pulse is largest. You’re amplifying something the body already wants to do.
The combination protocol is typically run for 12 to 16 weeks for meaningful muscle and body composition changes. Eight to ten weeks works for recovery support and general wellness goals.
Tesamorelin Dosage
Tesamorelin is typically dosed at 1mg to 2mg per day, injected subcutaneously. Most people run it in the morning on an empty stomach for best results.
If you’re stacking it with CJC-1295 and Ipamorelin, you don’t need to dramatically increase the other doses. Tesamorelin is doing its own work through its own mechanism. Stack them, don’t pile them.

Injection Timing
Timing matters more with GH peptides than with most other compounds.
Inject on an empty stomach when possible. Insulin blunts growth hormone release, so eating right before an injection works against you. Wait at least 90 minutes after a meal, or inject first thing in the morning before eating.
The pre-sleep injection is something I never skip. Growth hormone release peaks in deep sleep. Hitting Ipamorelin before bed is one of the highest-leverage things you can do in this protocol.
What to Expect and When
The first two to three weeks are mostly about sleep and recovery. People notice they’re sleeping deeper. Soreness clears faster. Energy during the day is more consistent.
Weeks four through six is when body composition starts shifting. The scale might not move dramatically but how you look in the mirror starts changing. Waist tightens. Muscle looks fuller.
By weeks eight through twelve you’re seeing the full picture. Muscle gains are real and visible. Fat, especially midsection fat, is down in a meaningful way. Strength in the gym has gone up. Recovery is dramatically better than when you started.
This isn’t a fast-acting compound like some other peptides. It builds. The people who stick with a full cycle are the ones who end up with results worth talking about.
Tips for Running This Stack Clean
Use bacteriostatic water for reconstitution every time. Not sterile water. Bac water keeps the peptide stable and reduces contamination risk.
Wipe every injection site with an alcohol swab. Fresh needle for every injection. Rotate your sites. These aren’t optional steps.
Protein intake needs to be high. Growth hormone supports muscle growth but your body still needs the raw material. I eat close to one gram per pound of bodyweight daily and I don’t skip that even when appetite is lower.
Take a photo before you start. I know it feels unnecessary. But eight weeks in when you’re not sure if anything is working, that starting point photo is going to settle the question fast.
Frequently Asked Questions
Where You Source This Matters
The reason I keep coming back to this point is because I’ve seen what happens when people cut corners on sourcing.
You can run a textbook protocol and get nothing if what’s in the vial isn’t what the label says. Concentration accuracy, purity, and identity testing are not things you can assume.
I source CJC-1295, Ipamorelin, and Tesamorelin from BioEdge Research Labs. Third-party certificates of analysis on every product. US-made. The lab reports actually match the vials. Use code MARS15 for 15% off. Pay by ACH or Cash App and you can stack another 10% on top of that.
