Peptide Comparisons
Not sure which peptide fits your research goal? These side-by-side comparisons break down how similar peptides differ in mechanism, dosing, and use case — like BPC-157 vs TB-500 — so you can see the tradeoffs at a glance before diving into a full profile.

Tirzepatide vs Semaglutide: Key differences comparison
Tirzepatide activates two gut-hormone receptors (GIP and GLP-1). Semaglutide activates only GLP-1. Here's how tirzepatide and semaglutide compare on weight loss, side effects, cost, and safety.

BPC-157 vs TB-500: The Wolverine peptide stack comparison
BPC-157 acts locally at the site of injury. TB-500 acts systemically through the bloodstream. Here's how BPC-157 and TB-500 compare, and why they're often combined into the Wolverine Stack.

Klow vs Glow: Key differences comparison
Klow and Glow share the same GHK-Cu, BPC-157, and TB-500 base. Klow adds a fourth peptide, KPV, for extra anti-inflammatory and immune support. Here's how Klow and Glow compare.

Melanotan 1 vs Melanotan 2: Key differences comparison
Melanotan I is selective for MC1R and stays focused on pigment. Melanotan II activates multiple melanocortin receptors, driving broader effects on appetite and sexual response. Here's how MT-1 and MT-2 compare.

Tesamorelin vs Sermorelin: Key differences comparison
Tesamorelin is FDA-approved for visceral fat reduction and is injected once daily. Sermorelin is no longer sold as an FDA-approved drug and is used off-label at bedtime for sleep, recovery, and anti-aging support. Here's how tesamorelin and sermorelin compare.

Tesamorelin vs CJC-1295: Key differences comparison
Tesamorelin is FDA-approved for visceral fat reduction and is injected daily. CJC-1295 (with DAC) is an unapproved research peptide that binds a blood protein, allowing once- or twice-weekly dosing for sustained GH release. Here's how tesamorelin and CJC-1295 compare.

Ipamorelin vs Sermorelin: Key differences comparison
Ipamorelin is a selective ghrelin-receptor agonist that produces a sharp, short GH pulse with little effect on cortisol, prolactin, or appetite hormones. Sermorelin is a GHRH analogue that signals the pituitary directly through a separate receptor, closer to the body's own nighttime GH rhythm. Here's how Ipamorelin and Sermorelin compare.

Selank vs Semax: Key differences comparison
Selank is a calming peptide studied mainly for anxiety and stress, working through GABA and serotonin signaling. Semax is a focus and brain-recovery peptide, working through BDNF and dopamine-related signaling. Here's how Selank and Semax compare, and why they're often stacked together.

Semax vs N-Acetyl Semax Amidate: Key differences comparison
N-Acetyl Semax Amidate is a chemically modified version of Semax, with an added acetyl group and amide cap that resist breakdown in the body, giving it a longer duration and a reported potency advantage. Here's how Semax and N-Acetyl Semax Amidate compare.

Selank vs N-Acetyl Selank Amidate: Key differences comparison
N-Acetyl Selank Amidate is a chemically modified version of Selank, built to resist enzyme breakdown so it lasts roughly 2.5 to 4 hours instead of 25 to 30 minutes. Here's how Selank and N-Acetyl Selank Amidate compare on evidence, dosing, and research status.

CJC-1295 vs Sermorelin: Key differences comparison
CJC-1295 (with DAC) binds to a blood protein, stretching its half-life to about 7 days so it's usually injected once weekly. Sermorelin has a much shorter half-life of about 12 minutes and is typically injected once nightly. Here's how CJC-1295 and Sermorelin compare.

Retatrutide vs Tirzepatide: Key differences comparison
Retatrutide is a triple GIP/GLP-1/glucagon receptor agonist that has produced the largest average weight loss seen in a Phase 3 obesity trial to date, but it's still investigational. Tirzepatide is a dual GIP/GLP-1 receptor agonist that's FDA-approved and available today. Here's how retatrutide and tirzepatide compare.
