### 4/5 — Need better blend support

*2026-03-01, version 49.3*

Have been waiting for the ability to calculate blends with more than three peps but still not available. Otherwise solid features.

### 5/5 — Ease of mind!

*2026-02-02, version 49.3*

This calculator is easy to use and I can track all my peptides and notes in a user friendly format.

### 5/5 — Awesome

*2026-01-19, version 49.3*

Takes the guess work out!!!

### 3/5 — Good just basic

*2025-12-26, version 49.3*

Good app but there’s better options available now for half the price

### 4/5 — It’s okay

*2025-12-18, version 49.3*

There’s better apps out there for free, it’s kinda boring

### 4/5 — Almost perfect

*2025-11-01*

Great app. Two very important things would make this app perfection.
#1. The ability to use 4 peptides in a formula. (Like KLOW)
2. The ability to change the "amount of peptide desired" to mg instead of mcg. It's a pain to have to do that math when an app can do it for you. Plus when it's a large number of mcg, you can't even see the whole number in the box. The box is too small.

Last recommendation would be for the paid version like I have is to include a option for cycle length or alarms to take your peps. Hope the developer reads this. Usually falls on deaf ears... Thank you.

### 3/5 — Need more options and clarity

*2025-10-29*

Wanted to purchase this app to make things easier for my protocols, wished there was an option for mg rather than mcg. As well the visual at the bottom is not clear and colours need to be adjusted for better clarity.

**Developer response:** Hi Nick,
Would love for you to give us another shot. 
Please go to the bottom of the Info tab and ensure you are on version 55.2.2. This version has a whole host of new features including the ability to convert between mcg/mg/g as you've requested.

We'd love to earn 1 or 2 more stars from you!
Cheers 🍻

### 5/5 — Excellent and Easy

*2025-10-20, version 49.3*

Ability to measure multiple peptide dosages in one syringe..like the Wolverine protocol . Quite efficient

### 3/5 — Almost there…

*2025-10-08*

The app interface is gorgeous. And simple to use. Which is great. But, I miss the ability to change units. For example, you can only input mcg as your dose. Would be really useful to use mg here. I’m sure the interface will continue to improve with updates. Not quite worth the 9.99 when there are better versions online.

**Developer response:** Hi Lohanski... are we there yet? 😀

Please go to the bottom of the Info tab and ensure you are on version 55.2.2. If you are then you'll have a whole host of new features. The most requested of which is the ability to instantly convert between mcg/mg/g for the draw amount. We've even added more gorgeous themes.

We'd love to earn a 4th or 5th star from you. We'll def keep updating an ensure you get bang for your buck. Cheers! 🍻

### 5/5 — Simplified peptide use greatly

*2025-09-19*

I was highly confused when it came to mixing peptide powders with water and then injecting, but this app made it easy. The founder even answered a question I had through email. Highly recommended.

### 5/5 — works great

*2025-08-05, version 49.3*

works well, love saved protocols

### 4/5 — Missing a few things

*2025-06-19*

Decent app which has saving capabilities which is nice to keep track of stuff. Would love other peptide related calcs like water amount recommendations which is trial and error otherwise. Also when editing a save you want to update, it’s possible to overwrite other saves since it’s a drop down.  Nice to have local than rely on a website, but more is warranted for a paid app.

**Developer response:** Hi bbman, we'd love to earn a fifth star!

Please go to the bottom of the Info tab and ensure you are on version 55.2.2. This version has a whole host of new features.

"Water Solver" is the next feature on our list and will be available soon. Keep an eye out! 👍

### 2/5 — Needs mg option

*2025-06-08, version 49.3*

I wouldn’t have bought this had I known they didn’t give a milligram option. Wasted my money.

### 5/5 — Great on a large screen!

*2025-06-04*

Many peptide calculators don’t work well when switching from the small phone screen to larger screen sizes. Now I’m a peptide pro regardless of my device.

### 2/5 — Lacking options for high price

*2025-06-02*

Wish there was the option to change desired dose from mcg to mg. Not worth $12.99. Should have shopped around before purchasing.

**Developer response:** Please go to the bottom of the Info tab and ensure you are on version 55.2.3. If you are then you'll have a whole host of new features. The most requested of which is the ability to instantly convert between mcg/mg/g for the draw amount. We've even added more gorgeous themes. And if you use notes the user experience has been vastly improved with full screen rich text editor now.

We'd love to earn a 5 star review from you. We'll def keep updating to ensure you get bang for your buck. Cheers! 🍻

### 5/5 — I’m not an idiot but calculations for reconstituting confused me at first.

*2025-05-15*

I didn’t quite understand micrograms compared to milligrams, even though I love the metric system and understand it. It took me a minute to figure out that micrograms are the measurements used in the dosing, whereas milligrams is just a general weight or concentration of the medicine. All that to say that by working with this app, it helped to solidify my understanding of it all.

### 1/5 — Waste of money

*2026-04-15, version 55.4*

The app does not let you update and save  the calculator do not make the mistake I did by purchasing.

### 1/5 — GARBAGE

*2025-11-18*

Don’t make my mistake

**Developer response:** Hey galo. Would love for you to give us another shot. 
If you do, please go to the bottom of the Info tab and ensure you are on version 55.2.2. This version has a whole host of new features. And one thing to keep in mind. Most "free" apps don't provide any useful features until you make a monthly subscription. PepCalc is a 1-time fee for lifetime use.

### 1/5 — Misinformed

*2025-05-11, version 49.3*

On the video that directed me to this calculator it stated that it would help me with every peptide. This is just a dosing peptide. Complete scam, there a plenty of free ones that do the same. I’m sure I won’t get my money back.

### 1/5 — Garbage not worth paying for

*2025-05-01*

App won’t calculate anymore. Have quadruple- checked the inputs and there’s nothing wrong with them. Absolute garbage considering I had to pay for this.

**Developer response:** We're so sorry to hear about the issue! 

Would you please reach out to hello@isjustawesome.com and share more details (like error messages or reproduction steps)? We’ve double-checked the calc function & it’s working, so we’ll sort this out for you ASAP.

### 1/5 — Wrong

*2024-07-02, version 49.3*

For some reason, the calculations are not correct. I did it 10 times and I got the same answer and it’s wrong. I went on the Internet and use their Calculator and it was correct.

### 1/5 — Doesn’t work

*2024-03-28, version 49.3*

You fill in all the criteria and it does not tell you how much to inject. The tick meter stays at zero.  App doesn’t work. It use to but stopped working. Don’t waste your money. There are free calculators online.

### 1/5 — Useless - Decimal point doesn’t work

*2024-01-19, version 49.3*

Adding a decimal point (ex: 2.5 ml for bac water) doesn’t work, making this app a waste of 5.99. Really disappointed

### 1/5 — Not as expected.

*2023-12-19, version 49.3*

How do I get a complete refund of this? This simply does not work as expected. The desired amount is unable to be edited beyond the first pep. This for me renders this pointless. Please help me process a refund.

### 1/5 — Not worth

*2023-11-22, version 49.3*

Not worth

### 1/5 — Can’t save

*2023-11-20, version 49.3*

Does not let you save the calculations. Not worth the money.

## Most praised reviews (10 highest-rated)

### 5/5 — Just what I needed

*2026-06-16*

Very easy to use and understand. Even calculates water to use. REQUEST: A cycle calendar and dose log would be a wonderful edition. That way I could have this as my one stop pep app. Thanks!

### 5/5 — With the price

*2026-06-09*

I tried many of the “free” apps. They were super annoying trying to force me to subscribe. This app after a one time payment and does everything i want. Thanks!

### 5/5 — Actual Customer Support

*2026-06-06, version 55.5*

I thought I as charged twice but I wasn’t.  I reached out via email and Someone Got Back to me!!

### 5/5 — Update-bugs fixed.   Was working great, but now there's bugs

*2026-05-04*

Update- reached out to Support and they fixed the app in a matter of days. 
All of a sudden, when I edited then saved the calculation to a saved protocol, it deleted all the notes that were there previously, which had not occurred in the past. It's also not letting me edit notes in saved protocols.

**Developer response:** Hi Aimee,
Sorry about this! Note loss is the worst kind of bug to ship and I'm sorry you got hit by it. The new "rich text" notes functionality added in the last release caused a couple issues.

I tracked down what was happening and the fix is already pushed. The "can't edit notes" issue is also fixed.

When opening the app it should update automatically. To ensure you have the new version check the bottom of the More tab for v55.5.2

Thanks for taking the time to flag this.  
I'm hopeful you'll also take the time to update your star rating if you see fit. 

Thanks!
Jeremy

### 5/5 — Best App!
