BEST PEPTIDES: S-Tier: Tirzepatide, Tesamorelin, Oxytocin A-Tier: Semaglutide, Sermorelin, Melanotan 1 B-Tier: NAD+ C-Tier: Everything else due to purity issues, until they can be legally compounded by US pharmacies (e.g. Retatrutide, BPC-157, TB-4, CJC, MT2, MOTS-c, etc.)
SKIP HYPE: If you want to HEAL faster, Skip BPC-157 (poor data) Take a Growth Hormone peptide (TESAMORELIN) If you want to lose FAT, Skip Reta (stimulates the heart) Take a GLP-1/GIP (TIRZEPATIDE) If you want to feel CALM, Skip Selank (poor data) Take a neuropeptide (OXYTOCIN)
@TheLongInvest For now, it's $HIMS. But I suspect it'll be $AVCT #AVCT in the not-too-distant future. The large majority of US retail associate #peptides with the GLP-1 mimetics (semaglutide, tirzepatide) and bioregulatory / research peptides (e.g. BPC-157; TB-500; GHK-Cu, etc.). But the
Amazon just launched a GLP-1 program through One Medical. $149/mo oral. $299/mo injectable. But GLP-1s are one peptide class out of dozens. BPC-157, Thymosin Beta-4, GHK-Cu, MOTS-c... the real wave hasn't even started. The FDA is deregulating 12+ peptides. Amazon is entering https://t.co/NqBTc9WhHt
🚨 $HIMS +46% in 1 week as FDA schedules peptide compounding review (July 23–24) The FDA will evaluate 7 peptides for compounding eligibility: → BPC-157, KPV, TB-500, MOTs-C, Emideltide, Semax, Epitalon ✅Hims & Hers CMO called it an “avenue toward trusted channels” This is https://t.co/yKIFM6lEZh
This week the FDA quietly admitted the research peptide community was right ALL ALONG!!!!! For 3 years they called BPC-157 "high-risk" and blocked access. No evidence. No bodies. Just bureaucratic theater. Now they're walking it back. Here's what it actually means 🧵
BREAKING NEWS: Peptides are coming In July, the FDA is reviewing BPC-157, TB-500, Semax, Epitalon and more. The meeting will be open to the public. The peptide era begins. https://t.co/hGR3ZPfhnU
Did a bit of research and seems like these are most used peptides: -tirzepatide -semaglutide -BPC-157 -TB-500 -ipamorelin What do you think of peptides?
