My Personal Experience Using Tesamorelin Dosage for Bodybuilding: Effects and Results
Tesamorelin: Why I Chose It for Building & Losing Fat
I’ve spent years as a bodybuilder honing my diet, training, and recovery methods to maximize my gains. But there’s always one area that’s our kryptonite, the final frontier of fat loss that just won’t budge. That’s when I started hearing about Tesamorelin, a peptide that’s rapidly emerging in the bodybuilding community for fat loss. Its also reputed to induce growth hormone release, which is useful for burning fat or at least preserving muscle mass.
Tesamorelin was originally approved for medical use specifically for the treatment of fat accumulation associated with HIV, but what really piqued my interest was its ability to target visceral fat, which can be notoriously difficult to lose. So many positive feedback on its bodybuilding effects like on Reddit, I had to give this a try for myself. I was looking to get leaner / more defined, and Tesamorelin looked like a great addition to my already extensive training.
Fat Loss and Bodybuilding Dosage I Used
I am all about starting slow and steady with any new supplement or peptide. The secret to the proper administration of Tesamorelin is to find the right dosage for your individual case and stick with it. Based on what I had learned from my own research, and from reading about other people’s anecdotes on bodybuilding message boards and Reddit, I chose to do a very specific dosing protocol. Here’s the approach I used:
Dosage: I began at 2 mg of Tesamorelin each day. So, after reading many success stories and consulting others that had used it, I discovered that this was the typical Tesamorelin dosage for fat loss bodybuilding enthusiasts followed when looking to shred fat whilst gaining lean mass. I took it subcutaneously (under the skin), and it worked best when taken in the evening, just before bed. This effectively mirrors the natural release of growth hormone that takes place in deep sleep to maximize fat burning in the body.
Administration: I injected Tesamorelin every day without fail. Skipped doses would have compromised my consistency, and I’d already figured out that consistency was the lure to get real results. Generally, the peptide is recommended for regular use without breaks.
Cycle Length: I opted to do an 8-week cycle and then 4 weeks off. I’ve always believed in cycling peptides so that you don’t build up tolerance and so that your body can have time to reset. Eight weeks would be long enough to see the full impact from Tesamorelin, and then four is enough time for my body to recalibrate and assess any responses after the cycle.
On the other hand, this seems like a rational middle ground when I weigh the broad long-term metrics one can expect based solely on my experience, versus to what I inferred with users write on subreddits like reddit, like bodybuilders who publish their experience and results with doses.

How I Performed: Fat Loss with Lean Muscle Gains
The effects with Tesamorelin were not immediate, but around the 4 week mark, I began to see some pretty impressive changes. If fissures in stubborn areas are an issue, patience is important for anyone seeking fat loss. Here’s what worked for me with Tesamorelin:
Reduction In Belly Fat: The biggest difference I saw was a reduction in the fat around my midsection. As a bodybuilder, I’ve always been mindful of my body fat, but doing cardio didn’t reduce my belly fat. Tesamorelin helped obliterate that fat, especially around my lower abdomen. After 8 weeks, I could see and feel a difference. Not a quick transformation, but slow, steady, sustainable.
Improved Muscle Definition: With the fat lost came a substantially more visible muscle definition. As the fat melted away, my abs, arms, and shoulders became defined. This was a massive confidence boost for me — I finally got to see tangible evidence of my efforts. It felt like my muscles were popping more clearly, and my entire body felt more sculpted.
More Energy: Another benefit I never saw coming was an increase in my energy levels. I noticed even faster than during my workouts — I feel more powerful and less fatigued. This was especially of benefit during high-intensity workouts. I was able to push harder with more energy and recover quicker, leading to better performance in the gym.
I used the dosage for fat loss and muscle definition and it really seemed to work fine, and the effects were just as good as I read about in other Reddit bodybuilders. Just keep in mind that what works for one person might not work for the next so while Tesamorelin helped me, some people may require different dosages or strategies.
The Response: Side Effects and Risks to Look Out For
However, although Tesamorelin had its benefits, I was also wary of possible side effects. Different peptides such as Tesamorelin have different user implications, so staying up to date and summarising user inclusions is important. From reading about other people’s experiences on Reddit and bodybuilding forums, I expected a handful of potential side effects:
Water Retention: Users on Reddit and other forums had reported experiencing some water retention while using Tesamorelin. Although I didn’t experience any major bloating, I did gained a small amount of water weight initially but as I carried on through the cycle that all disappeared. It wasn’t anything that sounded like a big worry, but it’s something to know about.
Joint Pain: This is also another very common side effect that some people report when using Tesamorelin due to its ability to raise growth hormone levels. That wasn’t a problem for me, but I’ve heard from others who told me they’ve experienced some tenderness in their joints. If this occurs, listen to your body and consider reducing the dosage or taking a break from the peptide.
(Other Side Effects: I didn’t have anything major, but it’s always good to pay attention to your health when you’re taking a new supplement.) It’s advised to see a health professional prior to beginning Tesamorelin and throughout the cycle to ensure you are in good health.

Bottom line: Is tesamorelin worth it for bodybuilding and fat loss?
I have been on Tesamorelin for 8 weeks now and I am happy with the results. Fat loss, especially around my midsection — a huge victory for me. I also saw more definition in my muscles and felt I had more energy for my workouts. Tesamorelin helped me really dial in my physique to attain the leaner, more sculpted look I was going for.
Would I recommend it? Absolutely—but with caution. Tesamorelin is not a miracle cure. It’s a tool that shines when used alongside a good diet and training plan. For bodybuilders already nailing their nutrition and training, Tesamorelin is the added benefit for getting leaner, getting more ripped. Just make sure you’re following proper dosage, paying attention to how your body moves, and getting clearance from a health professional before you start.
Ultimately, Tesamorelin helped me break through a plateau that I was feeling stuck on for a bit, and if you’re looking for a way to target stubborn fat while improving muscle definition, it could be worth looking into. As with anything in bodybuilding, the key word here is no shortcuts — there is no substitute for the grind, but when used correctly, Tesamorelin can serve to amplify your results.
