A short interview with Bob, the founder of ResearchChemHQ — peptide vendor since 2020. Why he started, how every batch gets HPLC + mass spec + endotoxin testing at an ISO-certified third-party lab, why domestic shipping matters, and what code REDDIT actually unlocks at checkout (10% off, stackable with their volume tiers up to 40%).
The short version
Bob runs ResearchChemHQ. Started in 2020. Domestic shipping. Every batch goes through Vanguard Scientific (ISO-certified, Olympia WA) for HPLC, mass spec, endotoxin, sterility, and heavy metals testing. Customers see the COA before they buy.
If you're shopping, code REDDIT is 10% off at checkout, and it stacks with their volume tiers — buy 5 vials of any product = 20% off the whole order, buy 10 = 40%.

The rest of this post is the actual conversation — i asked bob a few questions last week and he wrote back. forwarding what he said, exactly how he said it.
Why I'm posting this
I've been recommending RChQ through the peptide cheat sheet and the shred-stack post for a while, but never actually told you the why behind it. They're the cheapest source on basically every compound on our live $/mg comparison — retatrutide, tesamorelin, TB-500, cagrilintide, 5-Amino-1MQ, glow blend, you name it. The price tracker has been telling the same story for months.
So I asked bob a handful of questions about how the operation actually works. Here are the answers.
Q1 — Why did you start RChQ?
"i got sick of ordering peptides that cleared customs from somewhere i couldn't pronounce. yellow liquid that'd spike your CRP for two weeks. if i was gonna keep using this stuff anyway, i'd rather control the source than gamble. so i built one. that was 2020."
My read: This is the same story you hear from anyone who's been in this space long enough. The international peptide supply chain in the late 2010s was a mess of relabeled wholesale lots from Chinese chemical exporters, and a non-trivial fraction of what showed up at someone's door was either underdosed, contaminated, or the wrong molecule entirely. Building a domestic operation with batch-level testing was the obvious answer; very few people actually did it.
Q2 — What's different about your testing?
"every batch — every one — gets HPLC, mass spec, endotoxin, sterility, heavy metals. third-party. ISO-certified facility in the US. customers see the COA before they buy. that's not a marketing line. it's the only way the math works for me to sleep at night."
My read: This is the part that matters most for any peptide buyer. HPLC + mass spec confirms identity and purity. Endotoxin + sterility testing confirms it's safe for any actual research application. Heavy metals is a sanity check on the synthesis. Vanguard Scientific in Olympia is the ISO 17025-accredited reference lab a lot of the better US peptide vendors use.
The "you see the COA before you buy" part is what I keep coming back to. Most vendors will email you a COA if you ask. Very few make it the default.
Q3 — Shipping and support?
"domestic. out the door same day if you order before 1pm. discreet packaging. anything's wrong with your order, email me direct and i'll fix it that day. that part hasn't changed in four years."
My read: Domestic = no customs roulette, no frozen-in-transit issues, no 3-week waits. Same-day shipping with a 1pm cutoff is faster than most pharma e-commerce. Direct founder support is the kind of thing that scales poorly but matters enormously when something does go wrong.
Q4 — Anything for BHG readers?
"code REDDIT at checkout. 10% off. stacks with our volume tiers — 5 vials gets you 20% off the order, 10 vials gets 40%."
"and reddit's been vouching for us since 2021. we showed up early, didn't ghost anyone, people kept reordering. that's pretty much the whole story."
My read: Volume tiers are where the real savings live. If you're running a 12-week protocol and you know you'll need ~10 vials of retatrutide, the 40% tier turns the per-vial math into something that genuinely competes with insurance-subsidized brand pricing. Not "comparable to Wegovy self-pay" — beats it. Code REDDIT is their public-facing customer discount, not a unique-to-BHG coupon. It works at checkout for anyone who knows it.
What's actually worth grabbing
If you've never bought from RChQ and you want to start somewhere:
[Retatrutide (RC-3R) 10mg](/go/rchq-retatrutide?utm_source=blog&utm_medium=interview&utm_campaign=bob-interview&utm_content=reta) is their bestseller. Triple agonist (GLP-1 + GIP + glucagon). Phase 2 trials hit 24% body weight loss at 48 weeks. RC-3R is RChQ's product code — same molecule as the Eli Lilly clinical compound. Cheapest source we've tracked on the /compare page.
[Tesamorelin](/go/rchq-tesamorelin?utm_source=blog&utm_medium=interview&utm_campaign=bob-interview&utm_content=tesa) is the recomp pair. Visceral fat reduction + GH axis support. Pairs with retatrutide in the shred-stack protocol.
[TB-500 5mg](/go/rchq-tb-500?utm_source=blog&utm_medium=interview&utm_campaign=bob-interview&utm_content=tb500) is the recovery + tissue repair workhorse. Stacks with BPC-157 for the wolverine stack.
[Glow blend](/go/rchq-glow-blend?utm_source=blog&utm_medium=interview&utm_campaign=bob-interview&utm_content=glow) — GHK-Cu + epitalon + thymosin α1 in one vial. Skin + recovery + longevity in a single reconstitution. 70mg total. Easier than ordering three separate compounds.
Their full product list is at researchchemhq via /go.
The savings reality check
I ran the math on a 12-week recomp protocol (RC-3R + tesamorelin) using our cost calculator. At RChQ pricing vs the next-cheapest US vendor we track:
~$200-400 less over 12 weeks. Same molecule, same purity, same ISO-certified COA. They just don't carry the retail markup layer that some of the higher-priced vendors do.
That gap doesn't come from cutting corners on testing. The COAs are public. The lab is the same one a half-dozen better vendors use. The difference is operational — small team, no retail middlemen, founder still answers email.
How to verify any of this yourself
I'm an affiliate, so don't take my word. Here's what to do:
- Open [/compare](/compare) — our live $/mg tracker covers every active US peptide vendor. The tracker pulls fresh data weekly. Filter by compound and you'll see whether RChQ is actually cheapest right now.
- Ask for a COA before you buy. RChQ posts them, but the practice generalizes — any vendor who hesitates to send a COA on request is a vendor I wouldn't order from.
- Cross-check Reddit threads. r/Peptides and r/BodyHackGuide both have ongoing discussion threads on every major US vendor.
That's pretty much the whole pitch. Take the math or don't. The link still works tomorrow.
