Frag 176-191 is a synthetic peptide corresponding to amino acids 176-191 of human growth hormone. It promotes lipolysis while inhibiting lipogenesis, which is why it is commonly referred to as the “lipolytic fragment” of HGH.


Used to treat growth hormone deficiencies, Frag 176-191 aids in weight management while enhancing bone strength and muscle recovery. Researchers are now investigating applications of Frag 176-191 in the fields of fat loss, cartilage repair, and as a potential prediabetes and type 2 diabetes treatment.

    What is Frag 176-191?

    Frag 176-191 is a peptide that contains the exact sequence of amino acids numbered 176 through 191 found in human growth hormone (hGH). In other words, it is a synthetic fragment of hGH that mimics its end section known as the C-terminus [1].

    Although HGH Frag 176-191 has been tested in both animals and humans, it is currently available exclusively as a research chemical. It has demonstrated several effects in animals including promoting cartilage growth, reducing body weight, and influencing fat distribution.

    Much of the research on BPC-157 to date has been done in animals, but researchers are now using the findings to date to help direct further research into the ways BPC-157 may be beneficial for human subjects.

    It’s important to understand the potential side effects and risks of BPC-157—along with dosing considerations, and legal status of the peptide—before purchasing it for research.

    Our research team covers all of these questions below, before providing our top recommendation on where qualified researchers can buy BPC-157 online.


    Benefits of Frag 176-191

    While HGH Frag 176-191 is sold exclusively as a research chemical, there have been a number of animal studies and clinical trials that have explored this peptide’s in vivo effects. Based on the available data, here are the top five potential benefits of HGH Frag 176-191.

    1. Ability to induce fat loss

    Studies on both animals and humans have shown that HGH Frag 176-191 has a positive effect on fat levels and causes a dramatic reduction in body fat [1]. This effect is not exclusive to Frag 176-191; it is a function of hGH. Numerous clinical trials involving intact hGH have shown that it offers both fat-reducing benefits [2] and metabolic benefits [3]. The fat-reducing benefits of hGH appear to reside exclusively in the C-terminus section of hGH, which is the exact part of hGH that comprises Frag 176-191. In other words, Frag 176-191 appears to offer all of the fat-loss benefits associated with hGH treatment.

    2. Ability to reduce fat mass cells

    Frag 176-191 can have a positive effect on lipid mobilization and can reduce fat mass cells. Research shows that intact hGH can inhibit lipoprotein lipase activity in adipose tissue and stimulate lipolysis in adipocytes [4]. HGH Frag 176-191 is able to reduce fat mass cells to an extent comparable with intact hGH [5, 6].

    3. Ability to improve fat distribution

    The third main benefit of HGH Frag 176-191 is that it improves overall fat distribution to a comparable extent as hGH when administered to children [7]. This makes it extremely interesting for researchers looking to develop novel anti-obesity treatments and ways of helping people reduce their overall body weight.

    Research involving rats and mice has shown that Frag 176-191 reduces glucose levels (temporarily) and increases plasma insulin levels [8]. This, combined with a pronounced effect in thermogenic muscle activity [9], suggests that Frag 176-191 may help prevent and treat Type 2 diabetes. To date, the efficacy of Frag 176-191 for this purpose has not been studied.

    4. Cartilage regeneration

    The fourth potential benefit of HGH Frag 176-191 is its ability to aid cartilage regeneration. According to a 2015 study, white rabbits that received injections of both Frag 176-191 and hydrochloric acid (HA) experienced more cartilage growth than rabbits only treated with HA [10]. Based on these findings, Frag 176-191 may help provide an alternative to surgery for patients suffering from cartilage loss. This is a clear area where long-term clinical trials would be beneficial for increasing our understanding of this peptide.

    5. Favorable safety profile compared with hGH

    The fifth benefit of HGH Frag 176-191 is that it has a favorable safety profile and does not appear to cause common hGH-related side effects such as imparied glucose tolerance. Based on a review of six clinical trials involving Frag 176-191, this peptide did cause minor side effects including headaches, fatigue, dizziness, lethargy, abdominal pain, and injection site pain.

    However, it did not cause the more concerning side effects commonly associated with hGH administration, such as increases in IGF-1 levels, insulin resistance, and impaired glucose intolerance [1]. Researchers concluded that when comparing adverse events caused by Frag 176-191 and those caused by a placebo, the results were indistinguishable [1].

    These potential benefits illuminate the key areas in which ongoing research on Frag 176-191 may be warranted. In the following section, we’ll look at where to buy this peptide online.

    Where to Buy Fragment 176-191 Online? | 2024 Edition

    Buying HGH fragment 176-191 online is relatively straightforward, but there are caveats. In most countries, the peptide is sold as a research chemical, strictly for laboratory experimentation or in vitro testing.

    Those qualified to buy fragment 176-191 then face the challenge of finding a reliable and trustworthy source of research-grade peptides. The manufacture and sale of peptides are largely unregulated in most countries, and there are numerous companies claiming to offer pure fragment 176-191 online. But which company can researchers trust?

    Our team has made test purchases from numerous vendors to verify which are reliable and which fail to deliver on their promises.

    In our experience, the following vendor offers the best buying experience in the industry.

    HGH Frag Side Effects

    According to data from six clinical trials involving HGH Frag 176-191, there is no indication that it causes any of the serious side effects associated with long-term hGH use, such as IGF-1 increases, insulin resistance, and imparied glucose tolerance. Researchers in these trials noted that there was no distinguishable difference in the rate or type of adverse events caused by Frag 176-191 and those caused by a placebo [1].

    In total, around 900 test subjects were involved in these six clinical studies. The doses varied between 25 µg - 400 µg/kg body weight for intravenous injections and 9 mg - 54 mg for tablets and pills. All participants were given regular tests and did not experience any serious adverse events.

    This evidence points towards the fact that Frag 176-191 is a well-tolerated peptide that is appropriate for researchers wishing to safely study the fat-reducing benefits of HGH.
