Tesamorelin + Ipamorelin vs Sermorelin + Ipamorelin
Tesamorelin + Ipamorelin and Sermorelin + Ipamorelin are both blends peptides, which is why they get recommended interchangeably — but they are different compounds with different origins. The table below sets out the differences. We give no dosing guidance.
Side by side, in plain English — what each one is, where they overlap and where they genuinely differ.

The differences that actually matter
Both are classed as Blends peptides, so they get compared constantly and are often researched for overlapping reasons.
Where they overlap: combined in one vial, single reconstitution, one shared shelf life.
What Tesamorelin + Ipamorelin is
Tesamorelin is a synthetic analog of growth hormone-releasing hormone (GHRH) that acts on GHRH receptors in the anterior pituitary gland to stimulate the endogenous, pulsatile release of growth hormone (GH). Its modified structure provides enhanced stability and a longer half-life compared to native GHRH, allowing for sustained receptor activation. Ipamorelin is a selective growth hormone secretagogue (GHSS) that functions as a ghrelin mimetic, binding to the ghrelin/growth hormone secretagogue receptor (GHS-R) pri
What Sermorelin + Ipamorelin is
Sermorelin is a synthetic peptide that functions as a Growth Hormone Releasing Hormone (GHRH) analogue, interacting with GHRH receptors in the anterior pituitary gland to stimulate the pulsatile release of endogenous growth hormone. It is characterized by a relatively short half-life in the body. Ipamorelin is a selective growth hormone secretagogue (GHRP) that targets the ghrelin receptor, also known as the growth hormone secretagogue receptor 1a (GHSR-1a), primarily in the pituitary. This action further stimulate
How to compare them for yourself
Anecdotes online are noisy because nobody is measuring the same thing. The only comparison that means anything is your own: log each entry with a timestamp, keep the vial ledger honest so you know what you actually got through, pick two or three metrics before you start, and look at the trend after several weeks rather than day to day.
Peptide Wizard does that part for you — Tesamorelin + Ipamorelin and Sermorelin + Ipamorelin are both in the built-in reference library with a 3D vial, and your history, vial ledger and cost per entry stay private on your device.
FAQ
What is the difference between Tesamorelin + Ipamorelin and Sermorelin + Ipamorelin?
Both are classed as Blends peptides, so they get compared constantly and are often researched for overlapping reasons.
Can you log Tesamorelin + Ipamorelin and Sermorelin + Ipamorelin in the same period?
Plenty of people record more than one peptide at a time. Peptide Wizard keeps a separate vial ledger and entry history for each, so you can see exactly what overlapped and when — it does not recommend combinations or doses.
Which is better, Tesamorelin + Ipamorelin or Sermorelin + Ipamorelin?
There isn't a universal answer — reported responses vary a lot between individuals, which is why your own log is more informative than anyone else's anecdote. Track one variable at a time and compare your own metrics over several weeks.
