TB4-Frag daily vs full length TB-500 2x week, anyone switched and noticed a difference?

Question

5mg twice a week for the last couple cycles and it always seems to do the job for general recovery and keeping my tendons happy, but i keep seeing people talk about tb4-frag being the better option because of the shorter half life and better tissue penetration, for what it is worth i kinda wanna try it but the dosing is so different it is hard to know where to start. 5mg twice a week even though the total weekly amount kinda sorta lines up if you do the math. My question is has anyone here actually run both back to back and felt a real difference in healing speed or inflammation, or is the frag mostly just marketing? I am dealing with a cranky achilles that flares up when i push the volume on training and i am trying to figure out if switching to daily frag shots would be worth the extra pinning versus just sticking with what i know. Also wondering about timing, like does the shorter half life mean you really need to pin close to the injury site or does it still go systemic the same way. Any input appreciated.

I ran TB-500 for about 4 months and liked it, then switched to TB4-frag daily because honestly the twice a week pinning bugged me, fwiw. With the frag I went around 2-3mg daily and honestly could not tell you with any certainty that it healed anything faster than the longer one did. Both felt pretty systemic to me, I never did any fancy local pinning and my achilles which is also my problem child from years of squatting heavy and coaching classes seemed to settle the same either way. For what it is worth I think a lot of the "frag is better because tissue penetration" talk is mostly hand-waving from people selling it. The half life is shorter, sure, but in real life I did not feel like a daily poke gave me anything the longer chain was not already giving me. Might be placebo, might just be that my issue is more about load management than peptide choice. If your achilles is cranky on volume, the actual unsexy fix is usually dropping some volume and checking heel raise height before anyt

Not gonna lie the "better tissue penetration" thing always sounded like one of those things people repeat until it becomes gospel, so hearing you couldnt tell a difference is honestly useful data point for me. Did you ever try local pinning with the frag or was it purely systemic the whole time?
