These effects are usually temporary and dose-related
As an injectable peptide, MOTS-c carries the potential for certain adverse effects, including: Irritation at the site of injection Swelling or redness around the injection site Formation of nodules or lumps at the injection site Pain or discomfort during or after injection Bruising or discoloration at the injection site Rare allergic reactions, such as hives or difficulty breathing To minimize the risk of adverse effects, researchers are advised to purchase MOTS-c from a legitimate source and employ aseptic handling techniques in all laboratory procedures
In addition to directly obtaining TMAO from fish and seafood, it is more commonly produced by the gut microbiota through the conversion of foods rich in choline, L-carnitine, and ergothioneine (e.g., red meat, eggs, and mushrooms) (164)

A large number of pro-inflammatory factors such as interleukins IL-6, IL-8, IL-1, monocyte chemoattractant protein-1(MCP-1), ROS and T cell activation secretion regulator can infiltrate into the renal capsule from an abnormal glomerulus and destroy the function of the renal tubules ( Hyperglycemia, AGEs, mitochondrial oxidative stress and ultrafiltration cytokines act on renal tubular cells and trigger multiple cellular pathways such as PKC-, -, and -, NF-B, P38 and ERK1/2 pathways, further exacerbating renal tubular cell hypertrophy, apoptosis, and accumulation of tubulointerstitial inflammatory factors ( in vitro study has shown that high glucose induces the expression of TLR4 in PTECs through the activation of PKC, resulting in the upregulation of CCL-2 and IL-6 expression
Some people find it hard to use sublingual products or swallow pills, so liquid gel formulations might be easier to use
