What Is Phenylpiracetam Hydrazide?
Phenylpiracetam hydrazide is a synthetic racetam-class compound. It shares the phenylpyrrolidone backbone of phenylpiracetam (carphedon), but the amide side chain is replaced by a hydrazide group. That small structural change produces a distinct molecule, sometimes labeled fonturacetam hydrazide in chemical catalogs.
It is not the same as phenotropil, the brand name for plain phenylpiracetam developed in Russia. Nootropix sells the hydrazide form specifically, as Phenylpiracetam Hydrazide 150mg Capsules.
Important context: phenylpiracetam hydrazide is not an approved medicine in most jurisdictions. It should not be framed as a prescription substitute or used to treat ADHD, epilepsy, or any neurological condition without qualified medical care.
People typically explore this compound when they want stimulant-adjacent focus support on high-demand work, study, or competition days, not as a beginner daily nootropic. For racetam family context, see our Racetams 101 guide.
What phenylpiracetam hydrazide is not:
- Not a beginner default: Site copy positions it as advanced tier, reserved for specific high-demand days.
- Not for daily rotation: Frequent use may reduce perceived benefit and can affect sleep.
- Not an evening tool: Duration is long enough that late dosing may disrupt sleep.
- Not plain phenylpiracetam: Onset, feel, and tolerance may differ from the parent compound.
Hydrazide vs Phenylpiracetam (What Changes?)
Plain phenylpiracetam (carphedon) was developed in the 1980s and is discussed for cognitive and physical performance in preclinical and limited human contexts. Phenylpiracetam hydrazide emerged from earlier Russian medicinal chemistry work on anticonvulsant racetam derivatives, with the hydrazide modification altering receptor binding and metabolism compared with the parent amide.
Practical takeaway for shoppers: vendors often sell the hydrazide form when plain phenylpiracetam is difficult to source. That does not mean identical potency, duration, or side-effect profile. Community reports are mixed; some describe a milder feel than phenylpiracetam, others report similar drive with different timing.
No equivalence claims: Do not assume 150mg hydrazide equals 100mg phenylpiracetam or any other cross-compound conversion. Start at the labeled dose and assess your own response.

How It May Work (Mechanism)
Mechanism descriptions for phenylpiracetam hydrazide are largely inferred from the racetam class and phenylpiracetam pharmacology, not from robust hydrazide-specific human trials. The responsible framing is: these pathways are discussed in the literature for related compounds and may apply here, but direct confirmation in humans is limited.
| Pathway | What literature discusses | Hedged framing |
|---|---|---|
| AMPA / glutamate | Racetams modulate glutamatergic signaling linked to synaptic plasticity | May influence AMPA-related learning and memory circuits |
| Dopamine | Phenylpiracetam is discussed for dopaminergic motivation and drive | May support task initiation through dopamine-related pathways |
| Acetylcholine | Racetams often increase choline demand in sensitive users | May work best paired with a choline donor (see dosing) |
| Nicotinic receptors | Phenylpiracetam literature discusses nicotinic modulation | May support attentional processes; evidence is largely preclinical |
Stimulant-adjacent, not amphetamine-class: Many users describe clean drive and task initiation without the wired edge of high-dose caffeine. That is anecdotal, not a clinical guarantee.
What mechanism claims do NOT mean:
- Does not treat ADHD, epilepsy, or cognitive disorders
- Does not guarantee improved IQ, memory scores, or exam results
- Does not prove equivalence to phenylpiracetam or piracetam in potency
What the Evidence Shows (and What It Does Not)
Tier A: Best available data (phenylpiracetam proxy only)
Phenylpiracetam has more published material than the hydrazide form, including animal cognition studies and its documented development for cosmonaut performance research in the 1980s. That body of work informs what the broader phenylpiracetam class may do; it does not prove identical effects for the hydrazide derivative.
Plain phenylpiracetam (carphedon) appears on the WADA Prohibited List as a specified stimulant in-competition, which matters for athletes even when discussing related compounds (see safety section).
Tier B: Phenylpiracetam hydrazide-specific evidence
- First reported in 1980 as part of a Russian series on anticonvulsant racetam amides and hydrazides (Glozman et al., preclinical)
- Rodent anticonvulsant and electroshock models; ED50 values reported in animal studies
- Some radiolabeling and brain-uptake research in preclinical models
- Zero published human randomized controlled trials on phenylpiracetam hydrazide specifically
- Mostly vendor summaries, forum reports, and community anecdotes online
| Known / discussed | Unknown / unproven |
|---|---|
| Structural relationship to phenylpiracetam | Long-term human safety of hydrazide form |
| Preclinical anticonvulsant and neuropharmacology data | Standardized clinical dosing for hydrazide |
| Anecdotal reports of focus and drive on demand days | Disease treatment efficacy |
| Racetam-class choline stacking practice | Direct 1:1 potency vs phenylpiracetam |
When human trial data is thin, identity verification and batch testing become the practical quality signal for buyers.
Dosing and Timing
The following reflects Nootropix product labeling and common community practice. It is conceptual guidance, not a medical protocol. Individual responses vary.
Standard approach with Nootropix capsules:
- Dose: 1 capsule = 150mg; start with one to assess personal response
- When: Morning or early afternoon, ideally before 2 PM
- Duration of effect: Commonly reported 3-5 hours
- Frequency: Situational use on peak-demand days; not for daily rotation
- Stacking: Pair with a choline donor such as Alpha-GPC 250mg to support racetam tolerance and reduce headache risk
Practical rules:
Choosing between Alpha-GPC and CDP-Choline? See our Alpha-GPC vs CDP-Choline guide.
- Do not redose the same day until you understand your response
- Do not take in the late afternoon or evening if sleep matters
- Occasional use helps maintain perceived benefit; daily use may build tolerance
Powder users who want finer titration can see Phenylpiracetam Hydrazide Powder; capsules remove guesswork for most buyers.
Our Phenylpiracetam Hydrazide 150mg Capsules are pre-measured at 150mg per cap.

Safety, Side Effects, and Who Should Avoid
Phenylpiracetam hydrazide is not risk-free. Commonly reported effects in the phenylpiracetam class may include:
- Headache (often linked to insufficient choline)
- Insomnia (especially if taken late)
- Irritability or overstimulation in sensitive users
- Reduced appetite
- Tolerance with frequent use
Risk flags:
- Late-day dosing
- Daily or near-daily use
- Stacking with caffeine, other stimulants, or multiple racetams without assessing baseline response
- Pre-existing anxiety, sleep disorders, cardiovascular conditions, or seizure history
Athletes: Phenylpiracetam (carphedon) is prohibited in-competition under WADA. Phenylpiracetam-class compounds may be restricted by your federation. Verify current anti-doping rules before use in sport.
Who should avoid:
- Anyone under 18
- Pregnant or nursing individuals
- Anyone on prescription stimulants, seizure medications, or MAOIs without clinician guidance
- People seeking treatment for ADHD, epilepsy, or cognitive disorders (consult qualified care instead)
- First-time users who must drive or operate machinery before assessing personal response
If you take any prescription medication, consult a clinician before use.
Legality Notes (UAE and Beyond)
Regulatory status varies by country. Verify local rules before ordering, importing, or traveling with any compound. This section is general education, not legal advice.
Piracetam derivatives occupy a gray regulatory space in several jurisdictions. Some regions restrict phenylpiracetam specifically while allowing other racetams; rules change and enforcement varies. Nootropix ships from Dubai; confirm that your destination permits import of research compounds and nootropics before ordering.

COA and Batch Verification
When human trial data is thin, purity and identity verification become the quality signal. A Certificate of Analysis (COA) confirms that what is in the capsule matches the labeled compound and meets stated purity thresholds from an independent or qualified lab.
What to check on any phenylpiracetam hydrazide product:
- Identity matches phenylpiracetam hydrazide (not mislabeled racetam)
- Purity percentage stated with method (HPLC, LC-MS, or equivalent)
- Named lab on the report (not self-reported only)
- Batch or lot number ties your unit to a specific test
- Label shows exact mg per capsule (150mg, not vague "proprietary blend")
- COA date is recent enough to reflect current inventory
Request or download the batch COA from the product page before relying on any vendor claim. Match your unit to the report batch ID when buying from any source.
