Description
Researchers comparing options for a rad 140 and mk677 stack will find that this listing is a paired value pack rather than a blend: one 50ml bottle of RAD-140 (Testolone) solution at 10mg/ml and one 50ml bottle of MK-677 (Ibutamoren) solution at 25mg/ml, supplied with a 1ml measuring pipette. The two solutions arrive in separate, individually labeled bottles at their own concentrations, each carrying its own batch code and its own published laboratory documentation. The specifications set out below cover composition, CAS numbers, molar masses, storage guidance and available quality-control reports for both bottles, so the pack can be checked against a stated research requirement before ordering. For laboratory research use only. Not intended for human consumption.
What the RAD 140 and MK677 Stack Value Pack Contains
The pack is a single line item that holds two finished solutions and a measuring tool. The RAD-140 side is a 1% preparation at 10mg/ml in PEG400. The MK-677 side is a 2.5% preparation at 25mg/ml in ethanol and deionized water. Because the two concentrations differ by a factor of two and a half, the bottles are never interchangeable in a workflow, and both are printed with the compound name, the labeled mg/ml and the batch code so the material in hand can always be traced back to a specific release.
Both solutions are also listed on their own. The RAD-140 Testolone solution at 10mg/ml and the MK-677 Ibutamoren solution at 25mg/ml carry the same specifications, the same labeling and the same batch documentation as the bottles supplied inside this pack. The pack exists to put them in one order, at a combined listing price below the two individual listings added together, with the pipette included rather than bought separately. Every other paired listing sits together in the research value packs category if a different pairing suits the programme better.
What “stack” means on this listing
In search, “stack” is shorthand for buying two compounds in the same order. It is not a description of how they are used together, and it is not presented as one here. This listing is a packaging and purchasing arrangement only: two separate 50ml solutions and a pipette, grouped for convenience and priced as a set. It is not a premixed formulation, and no combination protocol, sequence, quantity or administration guidance is supplied, implied or available on request. Researchers design their own work. What the store supplies is characterised material with the paperwork that describes it.

Batch Documentation Published for Both Bottles
A paired pack is only as well documented as its weaker half, which is why the reports for both batches are published rather than summarised. The RAD-140 side is batch BA2166, with FTIR identity and HPLC purity results, plus separate concentration verification runs recorded as BA2166 #1 through #8. The MK-677 side is batch BA2183, with FTIR and HPLC results and its own concentration tests recorded as BA2183 #1 through #4. Every document for both batches can be read in the published lab report library, which covers 50 products across the catalogue.
The release criteria are the same for every batch and are described in full on the quality control page. An independent laboratory tests each batch before it is offered for sale. Compound identity has to be confirmed, raw material purity has to come back at 99% or higher, and for a solution the finished liquid has to test within 10% of the labeled mg/ml. A batch that fails any one of those checkpoints is not released. Testing the finished bottle matters here in particular, because a raw material result confirms what the powder is without confirming what ended up in the 50ml bottle at the labeled strength.
Reading the reports rather than the summary
The documents are worth opening directly, because each one answers a different question and a summary flattens them together. An FTIR spectrum speaks to identity: it confirms the material is the compound named on the label and not something that merely looks the same in a container. An HPLC trace speaks to purity, quantifying how much of the batch is the compound and how much is not. A concentration run speaks only to strength, and only for solutions, which is why there are eight of them on the RAD-140 side and four on the MK-677 side rather than a single figure. A pack that pairs two compounds carries two independent sets of all of this, and both sets are published under their own batch codes.
Ordering the Paired Pack and How Volume Pricing Works
Volume pricing is published on every product page and applies across the catalogue. A single bottle is full price. Two bottles take 5% off with free US shipping. Three or more bottles take 10% off with free US shipping. The reduction is calculated automatically in the cart, so there is no code to enter and no coupon to look for; the figures printed live on the listing already reflect the tier that applies. Prices are not quoted in this description because they are maintained by the store and change independently of the copy.
Payment is accepted by cryptocurrency, Cash App, Apple Pay and Chime. Card networks are not processed. If cryptocurrency is unfamiliar, the payment walkthrough and the current accepted methods are set out on the site rather than repeated here, since the accepted list is the store’s to change.
Why Buy the Paired RAD-140 and MK-677 Pack from Chemyo
Listings for a rad140 and mk677 stack vary widely in what they actually disclose. Some state a compound name and a volume and stop there. This listing takes the opposite approach: exactly what is in the box, the labeled concentration of each bottle, the full composition of each solution, the CAS number and molar mass for each compound, the batch code supplied, and the independent test documents behind both of those batches. Nothing in that list is difficult to publish, and a pack that pairs two compounds has twice as much to account for.
Everything else in the catalogue is documented the same way, whether it is a single solution, a bulk powder or another paired set. The full range can be browsed from the main shop listing, and each product page carries the same specification block, the same storage guidance and the same batch paperwork as this one.
Related Research Formats and Pairings
The MK-677 solution in this pack also appears in other pairings, so a programme built around a different second compound does not have to change supplier or format. The LGD-4 and MK-677 value pack substitutes an LGD-4033 solution at 10mg/ml for the RAD-140 bottle while keeping the same 50ml format, the same pipette and the same documentation standard. Both bottles in this pack also remain available individually at any time if only one of the two is needed, or if the two are wanted in different quantities than a paired pack provides.

Questions about this product
Is the RAD-140 and MK-677 value pack a premixed blend?
No. The pack holds two separate 50ml bottles at different labeled concentrations, one RAD-140 solution at 10mg/ml and one MK-677 solution at 25mg/ml, plus a 1ml measuring pipette. Each bottle is individually labeled and batch coded, and nothing is combined or diluted together before shipping.
Why is this listing described as a stack?
Because that is the term researchers search with when they want two compounds in one order. On this listing it refers to purchasing and packaging only. It is a paired value pack, and no combination protocol, sequence or quantity guidance is supplied, implied, or available on request.
Does the pack cost less than buying both bottles separately?
Yes. The pack is listed as one item priced below the two individual listings added together, and the 1ml measuring pipette is included rather than bought separately. Figures are printed live on the product page, so check the current numbers there rather than relying on a written amount.
What lab documentation is published for the two batches?
Both batches are documented. The RAD-140 bottle is batch BA2166 with FTIR identity and HPLC purity results plus concentration verification runs numbered one through eight. The MK-677 bottle is batch BA2183 with FTIR, HPLC and its own concentration tests. Every document appears in the lab report library.
Why test the finished solution and not only the raw material?
A raw material result confirms the compound is correct and pure before production, but it says nothing about what ended up in a 50ml bottle. Finished bottles are therefore tested by HPLC to verify the final mg/ml, and a solution must fall within 10% of its labeled concentration to be released.
