This short video compares the dead space in both. A syringe can retain 1–2 IU after the plunger bottoms out, while a pen tip holds under 0.5 IU. Small losses add up with frequent use.

Hit an "Unrealistic Goal". Got on the scale today and I'm 198 pounds. Seeing the scale go under 200 pounds for the first time in 30+ years is amazing. I was a teenager the last time I was under 200 pounds. This felt so unrealistic at the beginning of all of this but here we are. Coming to the end of the first 30 days of a 90 recomp. My daily steps have increased from 5k-8k a day up to a minimum of 11k a day. Im getting up and doing 2 miles before work. Running multiple days a week. Resistance training 4 days a week. The level of intensity and discipline needed to continue hitting these goals has increased immensely. Its really hard and challenging but so rewarding. So Happy Friday. Set some unrealistic goals for this Fall and do what you know needs to be done to hit them.

Did anyone have the measurements for this?

Before peptides this is how hard-core fatloss was done. Great book, lots of information on fat loss and body composition. This is how research was done. Personally one of the best books I read. Add this knowledge to your GLPs, you will kill it. Their journey will add to your foundation. https://music.youtube.com/podcast/XOiHp4qQrVo

Any way we can add a feature to filter vendors based on testing? Maybe a badge next to a vendor that does 7x testing, 5x testing etc so we can filter based on that

Medex 25 pack is now below $300. I hate to say this, but I told yaa all — this shortage, price hike, supply regular, price down (repeat) cycle has been going on for the past couple of years. People should stop falling for someone crying wolf and panic buying every time. People should also not wait till the last drop so they don't feel the panic and scarcity. My 2c!

They would appreciate it better if you left them a positive review... and the rest of us could see why you liked them.

This is a vendor review submitted by kimbreitbarth on PeptideCritic.com. Rating: (5/5) Review Purchased a GLP for research and the pricing was incredible. Labsourced offered a BOGO & allowed me to stack a welcome code with ach discount. Bought a large qty of 30 mg vials for less than ive seen anywhere. Im set for more than a year and plan to purchase more as a safeguard. Product arrived promptly, COA was available 3rd party and matched the vial lot code. Reconstituted my first vial mid Sept '26 with no cloudiness, gel or concerns. Injected without any side effects. Very happy.
