57 research compounds from ZestyRat Research, our top-rated research supplier — and not just vials. Oral GLP-1 capsules, ready-to-use nasal sprays, and a finished topical line almost no supplier carries. Built for researchers in Fresno, Clovis, Madera, Visalia and across the Central Valley. Every price is live, every batch ships with a certificate of analysis.
For research use only · not for human consumption
Reconstitution is where research protocols go wrong — wrong volume, wrong concentration, wrong storage. ZestyRat is the only lab in our network that solves it four different ways.
Orforglipron — a non-peptide small molecule built for oral bioavailability — plus Semaglutide in capsules. No needle, no cold chain.
Semax, Selank, the 50:50 combo, PT-141 and an Oxytocin:PT-141:VIP blend — pre-mixed at a stated concentration in 10ml bottles.
GHK-Cu face serum, BPC-157 + GHK-Cu cream, hair foam, PP405 scalp gel, topical rapamycin. Finished formulations, not raw powder.
BPC-157, KPV, NAD+, rapamycin, MK-677, dihexa, tesofensine and more — oral dosing for the compounds where it makes sense.
The eight compounds researchers ask for most, with live pricing straight from the lab.
Dual GIP/GLP-1 agonist. Four vial sizes from 10mg to 60mg, so protocol length is a purchasing decision rather than a reordering one.
Triple agonist hitting GIP, GLP-1 and glucagon receptors — the most-studied of the next-generation metabolic compounds. 14mg and 28mg vials.
The original GLP-1 receptor agonist — the reference compound in metabolic research, now also available as an oral capsule and as a co-formulation with BPC-157.
A non-peptide small molecule GLP-1 receptor agonist built for oral bioavailability — no reconstitution, no needle, no cold chain.
Melanocortin agonist acting centrally rather than vascularly. 20mg vial or 2mg/ml nasal spray.
Purity by HPLC. Identity by mass spectrometry. A batch number that matches the vial in your hand. ZestyRat provides one on every batch — and because the lab is independently tested, batch documentation is available on request rather than on a wish.
Semaglutide, tirzepatide, retatrutide, cagrilintide and the oral small molecules — the most-searched category in peptide research.
10 compoundsBPC-157, TB-500, KPV, GHK-Cu and the blends — tissue repair, mucosal signaling and the gut-focused protocols.
6 compoundsSecretagogues and GHRH analogs — CJC-1295, ipamorelin, tesamorelin, sermorelin, hexarelin, MK-677.
8 compoundsSemax, selank, cerebrolysin, dihexa, DSIP — the nootropic and sleep-architecture compounds, in vial and nasal formats.
9 compoundsEpitalon, NAD+, SS-31, rapamycin, thymosin alpha-1 — mitochondrial, telomere and immune-modulating research.
5 compoundsPT-141, oxytocin, kisspeptin, melanotan II — melanocortin and HPG-axis compounds, injectable and nasal.
5 compoundsFinished creams, serums, foams and gels — no compounding, no measuring, no reconstitution.
3 compoundsBacteriostatic water with syringe and needle, insulated heat-protection packaging, and special-order sourcing.

Fresno Peptide Lab does not stock, price, or ship anything. We publish the catalog, the research and the COA context — ZestyRat Research handles the order, the payment and the shipping.

A COA tells you what is in the vial. It does not tell you whether you are paying twice what the vial is worth. ZestyRat Research publishes third-party testing and prices well below the middle of this market. Across the 40 compounds more than one vendor stocks, ZestyRat holds the best value score on 26 of them and the lowest cost per milligram on 19 once the code is applied.
They carry a standing partner discount on top of that — no expiry date, no minimum, tested at a real checkout rather than scraped off a coupon site.
Prices and rankings above are read from live vendor storefronts and republished at our peptide price index. The ZestyRat link is an affiliate link — we may earn a commission at no extra cost to you, and it does not change what you pay or how the index ranks anyone.
We track pricing, stock and documentation across the research-peptide market every week. ZestyRat is the supplier we point readers to first, and the one our own readers order from most. It is the only lab on our list that clears every one of our four checks at once.
Ratings on this page are our own editorial assessment, based on published COA practice, checkout and shipping experience, and price tracking. We earn a commission on orders placed through our links, at no extra cost to you. Research use only.
Fresno Peptide Lab is an independent research library. We do not manufacture, stock, price, test or ship anything. We review suppliers on their published testing standards, reputation, fulfilment record and pricing, and the ratings we publish are our own editorial assessment.
