1,4-DMAA

1,4-DMAA is discussed for workout energy and reduced fatigue. Accounts include mood lift, jitteriness and disappointing blends. Unverified products and mixtures complicate comparisons with 1,3-DMAA.

What it is and why people discuss it

• A distinct DMAA isomer. 1,4-Dimethylamylamine is also called 1,4-dimethylpentylamine or 5-methylhexan-2-amine. The similar name 1,3-DMAA refers to a different arrangement of the molecule; an unqualified “DMAA” report cannot automatically stand in for either one. Official context
• The appeal is workout drive. In a pre-workout discussion, one user described energy, a modest mood lift and less muscle discomfort while training. That person found it less impressive than the recreational stimulants raised in the question, and was describing mixtures rather than an isolated-compound experiment. Personal report

Benefits people report

• Less fatigue, with a smoother feeling in one comparison. A commenter explicitly comparing 1,4 with 1,3 described less of a punch but easier endurance. They did not provide an amount or measured performance result; this is a personal comparison, not proof of better training capacity. Reddit · r/sarmssourcetalk
• Light energy, little extra drive. The E-Tech Greenies reviewer described light energy and a mildly better mood, but no increase in aggression or drive and less focus than expected. Multiple ingredients were involved, and the writer only described 1,4-DMAA as apparently present. Personal report

How it compares with 1,3-DMAA and other stimulants

• “Weaker” is an opinion, not a conversion rule. The AnabolicMinds discussion calls 1,4 weaker than 1,3, but gives no matched doses or detailed personal trial; the two comparison replies carry supplement-business affiliations. These posts cannot establish how many milligrams of one equal the other. AnabolicMinds
• DMHA and DMBA are separate compounds. They appear beside DMAA in pre-workout discussions, but the names are not interchangeable. A laboratory study found mixtures of these stimulant-family ingredients in supplements, including a product containing both 1,3-DMAA and 1,4-DMAA; that helps explain why a product review cannot settle a single ingredient’s effects.

Doses people discuss

• 10–20 mg in one strongly felt report; route and salt form unstated. The commenter named 1,4-DMAA and described jitteriness and trouble concentrating at amounts above that. Frequency was not given and other stimulant use was disclosed; this is neither a common-dose range nor evidence of a safe starting amount. Personal report
• 100 mg labeled HCl in one morning routine. Another poster listed that amount alongside S4 and beta ecdysterone, with MK677 and cannabis elsewhere in the routine. Route and course length were not stated; HCl means hydrochloride, and the reported mass is not a verified free-base amount. Personal report
• Capsule counts do not reveal 1,4-DMAA exposure. Two E-Tech Greenies capsules are a whole-product serving in one report, not a known amount of 1,4-DMAA. These unlike accounts should not be merged into a recommended dose range. Personal report Personal report

Half-life

• No usable community half-life estimate found. The inspected discussions do not establish the time for 1,4-DMAA levels in the body to fall by half. Felt duration and figures for 1,3-DMAA cannot supply that answer. AnabolicMinds

Onset: when people notice it

• About 40 minutes for mild focus in one capsule-blend report. The E-Tech reviewer took two capsules at 11:00 and noticed a small change around 11:40, followed by a mild head buzz around noon. This describes the mixture; no isolated 1,4-DMAA onset is established. Personal report

Duration: how long people feel it

• 4–5 hours from one pre-workout user. The person who described energy and less muscle discomfort later supplied this duration in the same thread. The product ingredients and amount were unspecified; the reply is a continuation of one person’s account, not independent confirmation. Personal report
• Around four hours for most effects in a different blend. The E-Tech reviewer said most effects had faded by then, with what they interpreted as caffeine remaining and no crash. A product can have several overlapping effects; neither account measures 1,4-DMAA clearance or a reliable bedtime window. Personal report

Repeated use and breaks

• A morning routine is reported; a useful cycle length is not. The poster listing 100 mg HCl later edited the account to say they had stopped everything. The dates of starting and stopping were not given, so the post cannot establish an on/off schedule or a tolerance-reset interval. Personal report
• Occasional use appears without a calendar. The commenter describing smoother stimulation said they rarely used DMAA or DMHA after obtaining modafinil. That is a change in personal use, not evidence that switching substances is a safe rotation or that a particular break restores sensitivity. Reddit · r/sarmssourcetalk

What deserves caution

• Strong stimulation can make focus worse. The labeled 1,4 product report includes jitteriness and difficulty concentrating, despite the author valuing its initial effect. Feeling less muscle discomfort during training also does not establish pain treatment or show that an injury is safe to load. Personal report Personal report
• FDA warns about cardiovascular harm. In its June 2026 PRE-FORMANCE BLACK notice, FDA identified undeclared 1,4-DMAA and warned about elevated blood pressure and problems including heart attack, breathlessness and chest tightness. This directly concerns 1,4-DMAA, although it does not quantify the risk of an isolated dose. Official context
• Supplement status and sport rules are different questions. FDA lists 1,4-DMAA as not a dietary ingredient under the U.S. food-and-drug statute. WADA’s 2026 list separately prohibits it in competition; an online “research chemical” label or a forum legal assurance settles neither issue. Official context Official context AnabolicMinds

From community discussion

• Nonresponse reports need their identity kept intact. The 2020 comparison thread includes a powder user who felt little at about 100 mg and another who described little beyond mild focus and energy after separate 50 mg and 100 mg trials. The discussion moves between generic DMAA and 1,4, so these are relevant disappointments with uncertain isomer identity, not confirmed isolated 1,4 failures. Reddit · r/sarmssourcetalk
• A changing product can look like a changing compound. The strong 1,4 report contrasts it with an ineffective product explicitly called 1,3. The author supplies no assay; differences in contents, co-use and personal response remain possible explanations rather than proof that either product was authentic or counterfeit. Personal report
• A weight-loss stack does not isolate a benefit or a harm. The morning-routine author was changing diet and exercising while using several substances. Their later explanation about cortisol and insulin resistance was speculation; the final update was that they stopped the entire stack, not that a specific 1,4-DMAA cycle solved the problem.
