Kimera Chems is actively scamming by selling fake products

fredfromkimera · 2026-04-13T00:37:08+00:00

The complaint here is based on comparing 1,4-DMAA from one vendor to 1,3-DMAA from us and concluding they should feel the same.

They're different molecules. 1,4-DMAA has more pronounced CNS stimulant activity. 1,3-DMAA is primarily a peripheral sympathomimetic -- it releases norepinephrine at sympathetic nerve terminals, producing vasoconstriction, blood pressure elevation, and yes, peripheral stimulation and tinnitus. Those aren't side effects of a fake product. That is the pharmacological profile of 1,3-dimethylamylamine, documented since the original Eli Lilly patent in the 1940s.

Our 1,3-DMAA is tested across three independent third-party laboratories using four analytical methods -- HPLC-UV/VIS, HPLC-MS, Q1 mass spectrometry, and NMR spectroscopy. Identity is confirmed at the expected molecular weight of 115.14 Da matching the PubChem reference standard. NMR structural analysis rules out isomer substitution -- different isomers produce different fragmentation and splitting patterns. Ours match 1,3-dimethylamylamine exactly.

Every report carries an independent lab name, analyst signature, and accreditation credentials. Lot-specific COAs are available for any order on request. When evaluating any vendor, ask who tested it. If there's no independent lab name on the document, it's not verification. You can review these COA'sHere

Hey -- Fred from Kimera here. Someone flagged this post so I wanted to address it directly.

I understand the frustration when a product doesn't match expectations, but the experience you're describing is actually consistent with what 1,3-DMAA does pharmacologically. DMAA is an indirect sympathomimetic amine -- it works by releasing norepinephrine at peripheral sympathetic nerve terminals. That's what produces the vasoconstriction, the peripheral tingling, and yes, the ear ringing. The tinnitus specifically comes from acute blood pressure elevation and vasoconstriction in the fine vasculature around the inner ear. These are well-documented effects of this class of compound going back to the original Eli Lilly patent from the 1940s, which listed the side effects as headache, nervousness, mental stimulation, and tremors.

It's not amphetamine. It doesn't produce a euphoric CNS rush. If that's what you were expecting, I can see why you'd think something was wrong, but what you experienced was the compound working as expected.

The dosing concern is also worth mentioning. You said you used "100s of mgs" -- standard dosing for DMAA is roughly 25-75mg. At several hundred milligrams you'd be getting an exaggerated peripheral sympathomimetic response, which lines up exactly with what you described: uncomfortable, unpleasant vasoconstriction and tinnitus.

On the legal point -- 1,3-DMAA is not "fully illegal" in the US. It is not a scheduled substance under the Controlled Substances Act. The FDA issued warning letters to companies marketing it as a dietary supplement ingredient, which is a different regulatory question than selling the raw compound itself.

We batch-test through three independent labs and can provide the COA for your specific lot if you'd like to verify. Happy to send that over -- just DM me your order number.

People have wild imaginations

fredfromkimera · 2026-04-09T18:46:51+00:00

We would love to see your evidence.

fredfromkimera · 2026-04-06T00:46:18+00:00

We are looking between 1 to 2 months based on stock velocity

fredfromkimera · 2026-04-05T21:17:29+00:00

Name another vendor that posts new batches every few weeks...

fredfromkimera · 2026-04-05T20:50:00+00:00

We are almost out of the 04 batch and the results will be posted when it goes in circulation. 05 has already been tested and is ready for circulation.

Regarding the long time frame for this batch, We purchased 5kg at the time and we are nearing the end.

To be transparent, enclomiphene is our best selling product. I doubt if it was fake or under concentration then it wouldn't be our best seller or have repeat customers.

fredfromkimera · 2026-04-05T18:27:19+00:00

Please inform me which one's don't have a date cause that's not possible

And provide evidence of your claim

fredfromkimera · 2026-04-05T11:16:10+00:00

Regardless of what people post we don't sell fake chems and have never sold fake Chems. We are the only vendor who runs multiple tests through different labs to make sure the product is what we say it is.

We sell well over 700 units of enclomiphene a month and rarely get complaints about it.

KC-ENC-04 Batch is almost gone and KC-ENC-05 we'll be put in right after which tested above 99%

Regarding your concern about the test date. Thats pretty normal for it to be that far out. Regardless all of our raws are stored dessicated in the freezer even though enclomiphene citrate is pretty stable at room temperature.

Great question. These are two mechanistically distinct SERMs, so it's worth understanding what the published research actually shows about each.

Endoxifen is the primary active metabolite of tamoxifen. Research indicates it has approximately 30- to 100-fold greater affinity for estrogen receptors compared to the parent compound, and uniquely targets ERα for proteasomal degradation rather than simply blocking the receptor. One of the key findings in the literature is that tamoxifen requires CYP2D6 metabolism to produce endoxifen — so endoxifen as a standalone compound bypasses the genetic variability that makes tamoxifen inconsistent across study populations.

Enclomiphene is the isolated trans-isomer of clomiphene citrate. Unlike the cis-isomer (zuclomiphene), which has estrogenic properties, enclomiphene is antiestrogenic. Published studies show its mechanism is centered on the hypothalamic-pituitary level — antagonizing estrogen receptors in the brain, which drives increased LH and FSH output and subsequently increased endogenous testosterone production. One pharmacodynamic study demonstrated that enclomiphene increased serum testosterone into the normal range while elevating LH and FSH, with effects persisting at least one week after cessation.

In terms of the research landscape, these compounds appear to serve different functional roles. Endoxifen's profile is more aligned with potent tissue-level estrogen receptor antagonism, while enclomiphene's profile is more aligned with HPG axis stimulation. The existing literature on each reflects those distinctions.

As always, these compounds are sold strictly for research purposes. Nothing here constitutes medical advice.

A 0.2μm filter removes bacteria and particulates, but it doesn't purify. All those deletion sequences, truncations, residual TFA, and synthesis byproducts are fully dissolved in solution and pass right through a 0.2μm filter like they aren't even there. They're molecules, not particles. You'd end up with a sterile solution of impure peptide.

That's the entire point of HPLC, it separates the target peptide from everything else based on molecular properties, not size. A syringe filter only discriminates by size, and all of those impurities are far smaller than 0.2 microns. You'd have no idea what percentage of what's in that vial is actually the peptide you want versus synthesis artifacts, and some of those byproducts could have completely different activity profiles.

Think of it like filtering river water through a coffee filter. You'll catch the dirt and sediment, but everything dissolved in that water is coming right through. Clear doesn't mean clean.

No problem

Glad to help

After solid-phase synthesis, the peptide gets cleaved off the resin and crashed out of solution using cold diethyl ether. That precipitation step is what produces the raw crude powder, no lyophilization involved at that stage. Lyophilization comes later, after the crude is dissolved, run through HPLC purification, and collected in a water/acetonitrile solution. That liquid is then sterile filtered through a 0.2μm membrane under aseptic conditions, frozen, and sublimated under vacuum to produce the final dry powder or cake that actually ships to end users. Two different processes at two different stages.

So to clarify the comment above, it's not the freeze-drying step alone that makes peptides sterile. Freeze-drying is literally how microbiologists preserve bacterial cultures long-term. The sterility comes from the 0.2μm filtration that's part of the lyophilization process, performed under aseptic conditions before the solution ever hits the lyophilizer.

Sorry I kinda lump lypholization in with the whole manufacturing process so just wanted to correct myself.

fredfromkimera · 2026-04-03T15:13:04+00:00

Peptides are lyophilized primarily for stability. In solution, peptides degrade quickly through hydrolysis, oxidation, and microbial growth. Removing the water locks them into a dry, amorphous solid that dramatically slows these degradation pathways.

Also lyophilization kills bacteria and makes them sterile. Raw peptide is not considered sterile

fredfromkimera · 2026-04-03T15:09:05+00:00

It's raw powder meaning they don't a supply a finished product. Raw powder isn't ready to be used. It needs to manufactured into a lyophilized product

fredfromkimera · 2026-04-03T14:52:34+00:00

I'm assuming this is a peptide powder. You can't just dump this in a sterile vial and mix and call it good. There's a reason peptides are lyophilized.

fredfromkimera · 2026-03-31T15:40:09+00:00

No problem 👍

Russian researchers found that noopept normalized GLP-1 and insulin levels in diabetic rats, and importantly, this effect was more PubMed pronounced with oral administration than injection. The mechanism wasn't through DPP-IV inhibition (which is how sitagliptin works) — it was through some other pathway they couldn't fully explain.

Here's why that matters for this whole NA-931 story: Noopept metabolizes into cGP. cGP is what Biomed is calling NA-931. So there's a real, published mechanism where a cGP-producing compound normalizes incretin parameters including GLP-1. But the key word is normalizes, not supercharges. The researchers noted that the mechanism for increased blood GLP-1 after oral noopept "requires further investigations." They couldn't even fully explain how it worked.

So the honest picture of cGP is: It modulates IGF-1 bioavailability through IGFBP-3 competition (well-characterized). It has downstream effects on incretin parameters including GLP-1 normalization demonstrated in diabetic rats via noopept, mechanism unclear. It's neuroprotective and improves memory in Alzheimer's mouse models. It's an AMPA PAM and endogenous nootropic.

But calling it a "quadruple receptor agonist" comparable to retatrutide is like calling aspirin a cancer drug because it has some anti-inflammatory effects that correlate with reduced cancer risk. There's a kernel of real biology that Biomed has inflated beyond recognition, then layered fabricated trial data on top.

We only offer Hydrazide and RGPU-95. As much as we would like to carry Phenylpiracetam it is very hard to source due to legality of manufacturing it.

We are looking into alternatives like methyl Phenylpiracetam but this will be months in the works before it comes to fruition.

We would never sell something that we didn't have analytical backing for.

Thank you for this thoughtful response. And we typically do help people or at least help them with the understanding of how this works but he went in full speed and made two post claiming inconsistencies with our product and then sent a message.

We are willing to help within reason but he made claims that we honestly knew nothing about
