I came across E4 in my research for scarring. I haven’t been able to find many sources, one from Phoenix labs for a high price, and another from NovoPto Labs

5mg with TFA removed for just over $200 is putting me off and makes me think it’s too good to be true. Has anyone else tried this vendor? Even better if anyone has tried this peptide from this vendor 

Then I did a ton of research about peptides. I loved the idea and was very excited to start. So I started taking tirzepatide peptide in September 2025.

But I didn't realize/research that tirzepatide is the same as mounjaro. I mean, I guess that part I knew but I didn't know that because I've been on it before, at the max dosage, that tirzepatide wouldn't work well for me unless I started basically at the highest dose right off the bat. Which really stinks because I'm on a very limited budget and when I bought the tirzepatide, I thought I'd have enough to last me over a year.

I knew I needed to switch to something else but I couldn't let this tirzepatide go to waste. So I was maxxing out my dosage of 15 MG a week.

Since September of 2025, I've only lost about 30 lbs. And none of it has been in the last several months. I've been the same weight for about 2-3 months. Although I'm grateful that I haven't gained any, but being stuck at a weight when I'm literally injecting myself weekly, feels yucky.

I decided to try retatrutide. I've been saving up money. I finally got enough and ordered it a couple weeks ago. Tonight is the first time I've tried it. I started at 1 MG. So far I don't feel any side effects but they could happen later, I imagine. I'm going to slowly. As slowly as possible, taper up but only when the dose I'm on is no longer working for me. 

I really really hope this works because if not, then I feel like a failure at weight loss. 

Anyone have any tips, secrets, or general information to share with me? I'll take all the advice I can get.

Thanks for reading 

Are there any EU-based suppliers that offer good quality control and transparent testing?

Which vendors generally offer the best price-to-performance ratio for these peptides?

Are there other peptides with similar effects (focus, cognition, stress resilience, etc.) that you would recommend looking into?

went through one vial, complained to company, they sent 3 more with the 'certificate' from freedom labs. all 3 did nothing. 

back to peptidesciences for retatrutide at 25$ per miligram. 15$ already seems retarded pricey. retat should cost 10$ or less per miligram but if it's fake crap, it's not a good deal. 

sad.;...attached 'certificate' from a lab is unquestionably inaccurate, or worse, fraud. there is not an iota of retatrutide in this product. not one of 4 vials. 

I'm looking into peptides and other injectables to help address these challenges.  My goals (in order):  more energy, quicker recovery from illness, quicker recovery from exercise, and better physique.  I've already started TRT, which has been helpful but not a total success.  (It seems to cause greatly increased hunger, among other issues.)

Below are the other products I'm considering.  In your experience, would this be a safe and efficacious cocktail?  What would you leave out?  What would you add in (peptide or otherwise)?  Any dosage recommendations?  Thank you in advance!
