HGH Dosage for tendon repair: A Comprehensive Guide

Recombinant human growth hormone (HGH) has emerged as the preferred pharmaceutical option for addressing conditions such as growth hormone deficiency (GHD). Its administration involves subcutaneous injections that necessitate proper mixing, dosing, and injection techniques.

Typically, healthcare professionals at specialized clinics oversee these procedures to ensure optimal treatment. However, in certain circumstances like the ongoing COVID-19 pandemic, some clinics may not be able to accept patients. Consequently, it is imperative that you liaise with your doctor to obtain comprehensive instructions on the intricacies of mixing, injecting, and dosing HGH.


Determining the appropriate dosage for HGH therapy can be accomplished through two primary methods: weight-based estimation and non-weight-based default starting dose. When assessing the dosage, factors such as the duration of HGH injection regimen, presence of any side effects, and individual body weight and body fat percentage must be taken into consideration.

It is of utmost importance to refrain from altering your prescribed dosage without first obtaining explicit approval from your doctor.

While this article aims to provide general information based on current scientific studies, it is crucial to consult an experienced medical doctor to receive tailored and effective treatment that aligns with your unique requirements.

How much HGH to take?

Determining the appropriate dosage of HGH depends on several factors, and two main methods are commonly used: weight-based and non-weight-based dosing.

The weight-based method involves calculating the dosage based on your body weight in kilograms (kgBW). Each HGH brand may have slight variations in their weight-based dosing recommendations for patients with growth hormone deficiency (GHD). Here are some examples:

  • Norditropin: The maximum starting dose is 0.004 mg/kgBW, which can be increased every 6 weeks up to 0.016 mg/kgBW.
  • Genotropin: The maximum starting dose is 0.006 mg/kgBW, and it can be increased every 4-8 weeks up to 0.012 mg/kgBW.
  • Humatrope: The maximum starting dose is 0.006 mg/kgBW, with the option to increase every 4-8 weeks up to 0.0125 mg/kgBW.

Alternatively, the non-weight-based method can be used as a general guideline for any growth hormone product. For patients with GHD, the typical starting dose is 0.2 mg/day (equivalent to 0.6 IU/day), which can be gradually increased by 0.1-0.2 mg every 4-8 weeks.

It's important to note that clinical trials have indicated that the weight-based method may lead to overdosing and side effects in overweight or obese patients. In such cases, starting with a fixed dose of 0.2 mg/day and gradually increasing it is recommended.

HGH injections should be taken once per day, 6-7 days per week, to replicate the natural pulsatile release of growth hormone in the body. The evening is considered the optimal time to administer HGH injections.

It's crucial to understand that the effects of growth hormone therapy may take time to manifest. Generally, it takes at least a month of therapy for noticeable benefits, such as abdominal fat loss and an increase in lean body weight. However, scientific evidence suggests that the majority of benefits, including improved mood, higher energy levels, and better quality of life, may take six months or longer to fully develop.

Dosage for Different Conditions in Adults 

In addition to growth hormone deficiency (GHD), there are other adult conditions that may require HGH therapy, such as Short Bowel Syndrome (SBS) and cachexia due to HIV. The optimal dosages for these conditions differ from those used for GHD and often involve higher doses administered from the beginning of therapy, without a gradual increase.

For Short Bowel Syndrome (SBS), HGH therapy is typically used as a short-term treatment lasting up to 4 weeks. The recommended dosage is 0.1 mg/kgBW daily or up to 8 mg/day. Longer-term effects of SBS therapy have not been extensively studied, but short-term therapies combined with other medications have demonstrated lasting results for up to 3 months.

In cases of HIV-associated cachexia, the recommended dose for HGH therapy is 0.1 mg/kgBW or up to 6 mg. This dosage can be administered daily or on alternate days for a duration of up to 12 weeks. Clinical trials involving HIV patients have identified common adverse effects associated with higher HGH doses, including elevated blood sugar levels, edema, and muscle and joint pain.

It is important to note that the dosages mentioned above are specific to these particular conditions and should not be applied to other scenarios without proper medical guidance. Dosage adjustments and considerations for individual patient characteristics should always be made in consultation with a healthcare professional.

What is the optimal HGH dosage?

Determining the optimal dosage of HGH depends on various factors, including the specific condition being treated and individual characteristics.

For patients with growth hormone deficiency (GHD), the optimal dosage typically ranges from 0.2 mg/day to approximately 1 mg/day. This dosage range takes into account factors such as the duration of HGH therapy, individual tolerance, efficacy, and the risk of potential side effects.

In addition to GHD, studies have explored the use of HGH at higher doses for shorter durations to target specific outcomes. For instance, in the context of anti-aging, muscle gain, or recovery from surgery or injury, higher doses have been examined. One study involving aged men and women demonstrated anti-aging effects such as improved whole-body protein turnover when using doses of 2 mg administered three times per week for up to 6 months.

It's important to note that optimal dosages may vary depending on the specific condition and goals of the individual. Determining the appropriate dosage should always be done in consultation with a qualified healthcare professional who can consider factors such as medical history, overall health, and individual response to treatment.

A study conducted on athletes investigating the effects of HGH on muscle gains found that a dosage of 5 mg per day administered over a 4-week period resulted in significantly increased muscle protein synthesis. Similarly, in trials involving surgery patients, higher doses of HGH (0.1 mg/kgBW daily) were found to expedite the healing process in less than a week of therapy.

However, it's important to note that such high doses of HGH should not be taken for longer than 3-4 weeks due to the increased risk of adverse reactions. Common reactions associated with higher doses include water retention, edema, muscle and joint pain, carpal tunnel syndrome, and headaches.

While current evidence suggests that low-dose HGH therapy does not increase the risk of chronic conditions such as diabetes, the long-term risks of high-dose GH therapy have not been fully investigated.

It's crucial to emphasize that an overdose of HGH, even as a one-time occurrence, can lead to acute adverse reactions such as shaking, excessive sweating, increased hunger, weakness, rapid heartbeat, and nausea. In such cases, it is imperative to immediately contact your medical doctor or other healthcare providers for immediate assistance.


The Benefits of HGH for Tendon Repair

Stimulated Collagen Production: Collagen is a crucial component of tendons, providing them with strength and flexibility. HGH can promote collagen production, potentially accelerating the repair of damaged tendons.

Anti-Inflammatory Properties: HGH may have anti-inflammatory effects, reducing swelling and pain associated with tendon injuries.

Cell Proliferation: HGH can stimulate cell growth and replication, aiding in the regeneration of damaged tendon tissue.
