unregulated peptides

Introduction

a number of synthetic injectable peptides are being sold which have not been approved and which may be harmful
their use is often driven by social media influencers who often spread medical misinformation
laboratory testing of grey-market vials reveals widespread mislabeling, inconsistent dosing, and heavy contamination
one of the reasons many of these peptides are not approved for human use is that there is not enough evidence of their safety
self-injecting unknown substances can cause local tissue damage, severe allergic reactions requiring hospitalization, kidney failure, and can be lethal
peptides interfering with hormone pathways and cellular growth could potentially stimulate cancers or disrupt endocrine function

whilst semaglutide (Ozempic / Wegovy) and tirzepatide (Mounjaro, Zepbound) have been approved
marketers have been selling un-approved peptides which may cause additional issues
see glucagon-like peptide-1 (GLP-1) peptide analogs (eg. Ozempic)

use of melanotan-II (MT-II) causes skin tanning but may also result in a multitude of atypical moles with potential increased risk of melanoma in the future¹⁾

mainly used to accelerate healing of tendon, ligament, and muscle injuries
derived from a protein naturally found in human gastric juice. It was first isolated and studied for its role in protecting and healing the gastrointestinal tract.
thought to work through several mechanisms, including:²⁾
- upregulation of growth hormone receptors in tendon and muscle tissue
- promotion of angiogenesis (new blood vessel formation)
- modulation of nitric oxide pathways to support tissue perfusion
- anti-inflammatory effects via interaction with the dopaminergic and serotonergic systems
- direct cytoprotective effects on the gut lining
there are currently no published randomised controlled trials (RCTs) in humans for BPC-157

a synthetic peptide derived from the naturally occurring protein Thymosin Beta-4, widely studied in preclinical research for its ability to promote tissue repair, reduce inflammation, and accelerate healing in muscles, tendons, and ligaments
primarily used as an experimental or veterinary agent. It lacks official medical guidelines and standard human dosing protocols
as it encourages cell migration and blood vessel growth, individuals with a history of cancer or elevated cancer risk are generally advised to avoid it.
long-term use requires careful immune monitoring
