Section 02
Peptides by Goal
The straight answer to "what peptide should I use for ___?" — hair, muscle, weight loss, sex drive, sleep and more. What people use, what actually works, and what's hype.
PT-141 vs Melanotan 2
PT-141 and Melanotan 2 are chemically related melanocortin peptides — PT-141 is actually a breakdown product of Melanotan 2.
Gonadorelin vs HCG
Both gonadorelin and HCG are real, prescription-only medicines used to keep the body's own testosterone (and, for HCG and gonadorelin, fertility) going — often alongside TRT.
Sermorelin vs CJC-1295
Sermorelin and CJC-1295 are close chemical cousins — both are GHRH-based peptides that nudge your body's own growth hormone.
CJC-1295 vs Ipamorelin
CJC-1295 and Ipamorelin are two different ways of nudging your body to release more growth hormone, which is why people talk about them together.
BPC-157 vs TB-500
BPC-157 and TB-500 are the two peptides the recovery crowd loves to talk about, and here's the honest version: neither is an approved medicine, neither has solid human evidence, and both are banned in sport.
Semaglutide vs Tirzepatide
Real talk: both semaglutide (Wegovy, Ozempic) and tirzepatide (Zepbound, Mounjaro) are real, approved, prescription-only weight-loss drugs — and both genuinely work.
Best Peptides for Beginners
Real talk for beginners: the only peptides worth touching on your own are topical cosmetic ones — copper peptides (GHK-Cu) and Matrixyl in a skincare serum.
Peptides for Belly Fat
Real talk: no peptide targets your belly specifically — spot-reduction is a myth.
Peptides for Endurance
Real talk: the endurance-peptide hype is thin on proof and heavy on risk.
Peptides for Immune Support
Real talk: one 'immune peptide' is an actual approved drug in a lot of countries — thymosin alpha-1, sold as Zadaxin — but it is NOT FDA-approved in the US.
Peptides for Women
Real talk: most 'peptides' hyped online were barely studied in women — a lot of the research is in men or animals, and that matters.
Peptides for Energy
Real talk: the 'energy peptide' hype is way ahead of the science.
Peptides for Testosterone
Real talk: there's no peptide you can order online that will safely and reliably fix low testosterone.
Peptides for Focus and Brain
Real talk: the 'nootropic peptides' Semax and Selank are genuinely interesting — they're approved and used in Russia.
Peptides for Gut Health
Real talk: the gut-healing peptide hype is way ahead of the proof.
Peptides for Tanning
Don't inject Melanotan-2 for a tan.
Peptides for Better Sleep
Real talk: there's no peptide with solid proof it fixes your sleep.
Peptides for Injury Recovery
Real talk on healing peptides: the hype is massive and the human proof is tiny.
Peptides for Anti-Aging
Let's be honest about anti-aging peptides: the science is thin and early.
Peptides for Sex Drive
Here's the honest deal on libido peptides.
Peptides for Weight Loss
This is the one category where the answer is a real yes.
Peptides for Muscle Growth
Real talk: no peptide is a shortcut to a physique.
Peptides for Hair Growth
If you want a peptide for your hair, the one with the most going for it is the copper peptide GHK-Cu, used in a topical scalp serum.
