Started tirz through telehealth back in late February, so about 6 weeks of actual data now. Phoenix, same question as half the posts in this sub: which provider, what’s the pricing, how flexible. Short version of what I found: the price comparisons people post are almost always apples-to-oranges because they’re comparing different dose sizes. One place quoting $199/month is usually shipping 2.5mg while another “expensive” one is sending 5mg. Once I normalized to mg-per-dollar, the gap between the “cheap” and “mid-tier” options was $25-30/month. Not nothing, but not the dramatic difference the charts suggest. What actually mattered more for me: Monitoring intensity. Some of these providers do a 5-minute async intake and ship product. Others want labs before and at 6 weeks. I wanted the second kind because I’m also running TB-500 and BPC for a left elbow injury from January, and I don’t want anyone guessing about what’s causing what if something looks off. Actual support pathway. Asked directly: if I have a side effect question at 11pm on a Sunday, what’s the process? “Message us” is not the same as “PA reviews within 24 hours.” A few providers answered this specifically. Most didn’t, which told me something. Contract language. Read this carefully. Some places auto-bill on a 90-day cycle and cancellation requires 30-day notice before the cycle renews. If your timing is off by a week you’re paying for a quarter you didn’t want. Not hidden, just buried. Six weeks in: 2.5mg, no nausea issues, appetite suppression was real by week 2. Running this for body comp going into summer, not weight loss specifically, there’s a difference when you’re training. Will post actual numbers at week 12 when there’s something worth reporting. If you’re in Houston the provider options are the same as anywhere since it’s all telehealth, so geography mostly doesn’t matter. Ask about the monitoring piece before you sign anything.
the part nobody’s flagging: you’ve got tirz running a caloric deficit underneath an elbow you’re trying to heal with TB and BPC. appetite suppression by week 2 means intake dropped, and energy availability plus protein intake are connective tissue recovery variables on their own, separate from either peptide. so if the elbow plateaus or the labs look off at week 6, you’ve now got three inputs moving, not two. the monitoring intensity you’re paying up for is the right instinct, but labs only separate causes if you pinned a baseline before any of this started. did you draw before february, pre-tirz and pre-peptide? if not, two points still beats one: draw now and draw again at week 12 and you at least have a comparison instead of a single number floating in isolation. the other thing is timeline. tendon and ligament don’t run on the glp-1 clock. appetite suppression shows up in two weeks, collagen remodeling on a mechanoload injury from january is a months-long process, and a deficit doesn’t help that side of it. body comp going into summer and elbow recovery are pulling in slightly different directions energy-wise, which is fine if you know that’s the tradeoff you’re making, less fine if the elbow stalls and you start blaming the BPC. fwiw i ran BPC solo first on a rotator cuff repair specifically so i wouldn’t have this problem, and even then i couldn’t cleanly separate it from concurrent PT. you’re stacking three things with a deficit on top, so attribution is basically gone unless the labs are tight. not saying don’t do it, just go in knowing the design can’t tell you which lever did what. agree hard on the contract language point btw. the 90-day auto-renew with 30-day notice is the part that actually costs people, and it’s got nothing to do with the compound. log your dose dates and your cancellation window the same way you’d log a titration schedule, because that’s the variable that bites when you’re not watching it.
the distinction between muscle protein floor and connective tissue repair floor doesn’t come up in these threads and it should. tirz suppressing appetite by week 2 means total intake dropped, but even if you’re hitting your daily protein number, collagen synthesis runs on glycine and proline density specifically, which most standard protein targets don’t optimize for. there’s research on timed collagen dosing with vit C before mechanical loading of the injured site, roughly 15g hydrolyzed collagen 30-60 min pre-PT session. it’s a separate variable from your daily macro count and doesn’t conflict with anything else you’re running.
the glycine/proline point is legit and people gloss over it. collagen synthesis is substrate-limited in a way whey-heavy protein targets don’t cover, and the pre-loading window with vit C is real mechanism, not bro-science. so the case for adding it is fine on its own terms. where I’d push back is “it’s a separate variable that doesn’t conflict with anything else you’re running.” no interaction isn’t the same as no attribution problem, and those are getting collapsed here. you’ve already got TB-500, BPC, and a tirz-driven caloric deficit all moving on the same elbow. adding timed collagen is a fourth input. it won’t chemically fight the others, sure, but if the elbow improves you now have four candidates and zero way to say which one did it. that’s the exact thing you said you wanted to avoid when you picked the labs-at-6-weeks provider so “nobody’s guessing what’s causing what.” the collagen move quietly reintroduces the guessing. second thing: that pre-loading research is close to a single-lab literature. most of what gets cited traces back to one group’s gelatin/vit-C-before-jump-rope work, small n, and the endpoint was collagen synthesis markers in blood, not healed-tendon outcomes or anything elbow-specific. i’m not saying it’s wrong, partial replication from an independent group would move me a lot, but it’s thinner than “there’s research on” makes it sound, and the geometry of a forearm tendon/epicondyle isn’t the same substrate they tested. if you actually want to know whether collagen does anything for you, the cleaner play is to not start it the same week as everything else. let the TB/BPC arm run, get a read, then add collagen as its own block with the elbow as a tracked endpoint (pain on loading, grip, whatever you can measure repeatably). otherwise it’s just one more thing in the pile that “helped,” same way every stacked-protocol post can’t tell you anything. fwiw none of that means skip it. cheap, low risk, plausible mechanism. just don’t expect it to be readable as data the way you’ve set the rest up.
