Biotinoyl GHK, sold as Biotinoyl Tripeptide-1, is the copper peptide GHK with a biotin group attached to its N-terminus. It reaches consumers almost entirely inside Procapil, a three-part hair blend. ⚠️ Two things make it much weaker than its reputation. The biotin caps the exact chemical site GHK uses to carry copper, so it cannot work the way GHK-Cu is supposed to. And the whole of PubMed holds three papers on biotinylated GHK, none of which measures a single target.
TDM-105795 is a topical thyroid hormone receptor agonist developed by Technoderma Medicines for pattern hair loss, and licensed to Cutia Therapeutics for Asia. ⚠️ It has no peer-reviewed publications of its own data; everything verifiable about it comes from a patent, a stock-exchange prospectus and a trial registry. The one animal study usually cited for it studies a different Technoderma compound, and no test of receptor selectivity has ever been run, which makes the common description of it as a beta-selective agonist unsupported.
